She checks to record both events but remembers from the maintenance manual that these observations indicate two early warning signs of one problem: moisture and air entering the closed oil system of the transformer. The same thing happened in a transformer of another company when ten years ago the equipment failed when it experienced the same problems. After the accident, the dissolved gas analysis report indicated that there were signs of rising hydrogen levels which had been longtime visible in the breather condition. The issue was detected by the gas relay \u2013 in this case, it features a Buchholz relay.<\/p>\n<p>The article provides the details about how breathers and gas relays operate in an oil transformer, their importance, how to interpret their signals, and what a new unit costs.<\/p>\n<blockquote><p>The breather is a part of oil conservator. It is a silica gel-based device that removes moisture from air drawn in through oil conservator while the transformer breathes. The gas relay is another protective device that is normally installed in between the conservator and the tank to detect gas accumulation due to malfunctioning of the transformer. A breather&#8217;s price normally ranges between $50 and $300 and the gas relay usually costs between $100 and $600. Generally, all power transformers of rating above 1 MVA must be equipped with gas relays (IEC 60076-1 standard). It is obligatory for all conservator types to utilize breathers. The silica gel in the breather must be checked on the regular basis every 3 to 6 months and regenerated when it changes color.<\/p><\/blockquote>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-400\" src=\"https:\/\/subian-electric.com\/wp-content\/uploads\/2026\/08\/Core-Functions-Of-Breather-And-Gas-Relay-In-Oil-Immersed-Transformers.webp\" alt=\"Core Functions Of Breather And Gas Relay In Oil Immersed Transformers\" width=\"1448\" height=\"1086\" \/><\/p>\n<hr \/>\n<h2 id=\"why-needed\">Why Oil-Immersed Transformers Need Both<\/h2>\n<p>The oil used in oil-immersed transformer carries out dual functions of cooling and insulation. Both functions can be jeopardized by the two enemies against which gas relays and breathers protect \u2014 moisture and gas from internal faults. An oil-filled transformer breathes because the oil expands and contracts with temperature: as the load increases, the oil heats up and expands and pushes the air out through the breather. When the oil cools down, the air comes back into the tank. Without a desiccant breather, the air would bring the moisture to the oil as water is the fastest way to insulation failure. Just a few hundred parts per million of water in transformer oil can dramatically affect its dielectric strength \u2014 the breakdown voltage can be lowered from 60+ kV to below thirty kV with increasing moisture.<\/p>\n<p>Gas relays fight the other battle. Internal faults \u2014 shorted turns, core faults, loose connections \u2014 create heat and discharge electrical arcs, which decompose oil into gases. The formed gases rise to the top of the tank and go to the conservator through the pipe leading to the gas relay, thus allowing gas relay to detect gas way before other protection can see it.<\/p>\n<h2 id=\"breather\">The Breather: Function and Design<\/h2>\n<p>A dehydrating breather is a cylindrical unit that is installed on the air inlet of a conservator, usually on top of a conservator tank. The breather uses the desiccant material that is usually silica gel through which all the incoming air passes. The silica gel takes away moisture from the incoming air before it goes to the oil. A change in color of silica gel from the active status (mostly blue) to the hydrated one (pink, white, or orange depending on the grade) indicates the amount of capacity left for the desiccant to absorb moisture.<\/p>\n<p>The unit typically has an oil seal or a non-return valve for preventing saturation of the desiccant with water due to rain splash. The device also allows gas to escape and does not allow moisture to enter. Modern breathers can come with an indicator window, removable cartridge with desiccant for renewal, and a heater in cold environments where moisture can condense inside the unit. A usual dehydrating breather can weigh between one and three kilograms of silica gel and work for many transformers of just a couple of MVA; a bigger scale requires bigger housing or a combination of some breathers.<\/p>\n<h2 id=\"gas-relay\">The Gas Relay: Function and Design<\/h2>\n<p>The gas relay \u2014 commonly referred to as Buchholz relay after its inventor Max Buchholz (1921) \u2014 is positioned in the piping system that connects the main tank with the conservator, having a slight inclination which leads to rise of gas. It includes two float switches and some types have a barrier which distinguishes waves.<\/p>\n<ul>\n<li>Gas accumulation: Small internal faults cause slow accumulation of gas. As a result it pushes oil upwards in the upper tank chamber which reduces the level of the upper float and closes the alarm contact. Then the technician can vent the relay and make gas samples for examination.<\/li>\n<li>Oil surge: When a big fault happens, e.g., short circuit of winding, oil begins to surge from the tank to the conservator at high velocity. The baffle is released and makes the lower float move downwards thereby closing the trip connection which leads to disconnection of the transformer.<\/li>\n<\/ul>\n<p>In this way, Buchholz relay becomes the first and the most effective protective device as it notices the emergence of fault even before current rises enough to disconnect the transformer.<\/p>\n<h2 id=\"types\">Types of Gas Relays and Breathers<\/h2>\n<table>\n<thead>\n<tr>\n<th>Taper<\/th>\n<th>Description<\/th>\n<th>Typical Price Range<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Standard silica gel breather<\/td>\n<td>1-3 kg desiccant column, oil seal, window<\/td>\n<td>$50-$300<\/td>\n<\/tr>\n<tr>\n<td>Large-capacity \/ industrial breather<\/td>\n<td>5-15 kg column for power transformers, heater option<\/td>\n<td>$300-$1,500<\/td>\n<\/tr>\n<tr>\n<td>Color-change indicating breather<\/td>\n<td>Blue-to-pink silica gel, replaceable cartridge<\/td>\n<td>$80-$400<\/td>\n<\/tr>\n<tr>\n<td>Classic Buchholz relay (float type)<\/td>\n<td>Two floats, gas alarm + surge trip, glass sight<\/td>\n<td>$100-$500<\/td>\n<\/tr>\n<tr>\n<td>Electronic \/ smart gas relay<\/td>\n<td>Added sensors, remote indication, DGA-ready port<\/td>\n<td>$400-$1,200<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>In the case of a distribution or industrial transformer, the Buchholz float type relay and a color change silica gel breather are the tools of preference, simply because they are the most reliable and the cheapest.

For desiccators, go with the amount of desiccant according to the oil capacity of the transformer and the breathing rate, with a usual rule of thumb that, for distribution equipment, use around 1 kg of silica gel for every 1,000-2,000 liters of oil.<\/p>\n<h2 id=\"maintenance\">Maintenance Intervals and Procedures<\/h2>\n<p>Both devices are inexpensive, easy to use, and frequently ignored, which is what causes the devices to fail to perform their functions effectively. A logical plan is as follows:<\/p>\n<ul>\n<li>Breather \u2013 every three to six months check the color of the silica gel. Replace or regenerate the gel when it has become ineffective. Blue silica gel can be dried out by putting it in an oven set to 105-120\u00b0 C and keeping it there for several hours until it returns to its blue color.<\/li>\n<li>Gas relay \u2013 once per year check that the device functions by opening the test valve through which the alert contact closes whenever the device operates.<\/li>\n<li>Gas relay \u2013 for each oil dissolved gas analysis, compare the accumulated gas content with the gas records inside the body of the transformer.<\/li>\n<li>Breather seal \u2013 once per year ensure that oil levels and non-return valves are at an appropriate level. The dried out seal means potential humidity entering via breather\u2019s own port.<\/li>\n<\/ul>\n<p>The cost of that simple monitoring may be a few hundreds of dollars per year, while the costs of not monitoring them may lead to moisture-affected windings or non-detected internal failures leading to a complete transformer rewind costing, on the average, 50-80 percent of a new transformer.<\/p>\n<p>When gas relay gets a sample, gas concentration shows what caused the fault to occur as this is what the lab involved in dissolved gas analysis always checks first.<\/p>\n<table>\n<thead>\n<tr>\n<th>Gas Signature<\/th>\n<th>Indicated Fault<\/th>\n<th>Recommended Next Step<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>High H\u2082 + C\u2082H\u2082 (acetylene)<\/td>\n<td>Arcing in the winding or core<\/td>\n<td>Internal inspection; winding resistance and turns-ratio tests<\/td>\n<\/tr>\n<tr>\n<td>High H\u2082 alone (low concentration)<\/td>\n<td>D\u00e9charge partielle<\/td>\n<td>Continue DGA monitoring; check for loose hardware<\/td>\n<\/tr>\n<tr>\n<td>High C\u2082H\u2084 + C\u2082H\u2086 (ethylene\/ethane)<\/td>\n<td>Thermal hot spot (overheating)<\/td>\n<td>Check load profile, cooling, oil level; repeat DGA in 1-3 months<\/td>\n<\/tr>\n<tr>\n<td>High CO + CO\u2082<\/td>\n<td>Paper\/insulation ageing or overheating<\/td>\n<td>Furan analysis; estimate remaining insulation life<\/td>\n<\/tr>\n<tr>\n<td>Nitrogen-dominated with no fault gases<\/td>\n<td>Normal breathing \/ no internal fault<\/td>\n<td>Continue routine monitoring<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"applications\">Where They Are Used<\/h2>\n<p>Breathers and gas relays can be found on many oil-filled transformers with conservators, typically from 50 kVA and on up.

Choose a conservator connection diameter (nominal bore DN50-DN80) and the transformer\u2019s rating to ensure the contact ratings for the trip circuit are suitable.<\/li>\n<li>The breather should be selected according to the oil volume in the transformer. The higher the volume of oil, the higher the breathing rate and the amount of desiccant; ensure that you have a heater installed if you are working under frosty or humid conditions.<\/li>\n<li>Make sure that the relay is positioned correctly. A slope of 1-5\u00b0 toward the relay is recommended to ensure that the gas collects in the relay\u2014make sure that the arrow on the relay indicates the conservator.<\/li>\n<li>Connect the alarm and the trip circuits separately. The gas alarm must be connected to SCADA; on the contrary, the surge trip must be wired to the transformer breaker circuit.<\/li>\n<li>Place the breather on the highest point of the pipe. The air intake must be placed above the maximum oil level in the conservator so that the oil cannot flood the desiccant.<\/li>\n<li>Specify the devices in the contract. Indicate the type of relay and the capacity of the breather in the purchase order, and make sure you have their testing reports in the delivery certificate.<\/li>\n<\/ul>\n<h2 id=\"faq\">Questions Fr\u00e9quemment Pos\u00e9es<\/h2>\n<h3>How much does a breather and gas relay cost?<\/h3>\n<p>The price of a standard silica gel breather with a weight of between 1 kg and 3 kg varies from 50 to 300 dollars; that of a large power transformer breather is in the range of either $300 to $1,500 or above. A traditional Buchholz gas relay costs between $100 and $500, while an electronic one with remote monitoring costs between $400 to $1,200. Both accessories amount to not more than three percent of the price of a complete transformer.<\/p>\n<h3>How often should I check or change the silica gel in the breather?<\/h3>\n<p>Perform visual checks on the color at least every three to six months, more frequently in humid environments. If the blue gel becomes pink or white, it is fully used up. Regenerate it by heating it to between 105 \u00b0C and 120 \u00b0C until its color becomes blue again or replace it altogether. If the saturated breather is not replaced, moisture will enter the oil leading to failure of the insulation system.<\/p>\n<h3>What does the gas relay actually detect?<\/h3>\n<p>This device can identify two kinds of faults. First is gas build up caused by a slow internal fault where the gas forces the oil to displace the float which causes an alarm contact. Second is a sudden surge of oil caused by a severe fault that moves a baffle which opens the transformer&#8217;s circuit breaker instantaneously. The gas collected can be analyzed to determine its composition (hydrogen, acetylene, ethylene) thereby informing whether the fault was due to arcing, hot spots, or partial discharge.<\/p>\n<h3>Why does my gas relay alarm keep operating with no load change?<\/h3>\n<p>A repeat gas alarm with normal load generally indicates that there is an internal fault, usually a loose connection, a shorted turn, or overheating of the core. Avoid resetting the alarm without first taking gas samples and performing gas-in-oil analysis.If the gas alarm is triggering often, it indicates that the transformer requires the conduct of internal tests (insulation resistance, turns ratio, and winding resistance tests).<\/p>\n<h3>Can a transformer run without a gas relay?<\/h3>\n<p>The statement is technically correct. However, it is bad practice and non-compliance to use Buchholz on transformers with a power rating more than approximately 1 MVA, where protection is mandatory, according to IEC 60076-1. The Buchholz relay is the only piece of equipment detecting the developing internal faults before phase-to-phase short-circuit occurs. Without it, the first sign of fault may be the catastrophic trip or fire. The cost of the relay is between $100 and $600, and this relay is considered one of the cheapest forms of protection in substations.<\/p>\n<h2 id=\"references\">R\u00e9f\u00e9rences<\/h2>\n<ul>\n<li><a href=\"https:\/\/webstore.iec.ch\/en\/publication\/27175\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60076-1 \u2014 Power Transformers, General Requirements<\/a> \u2014 The master standard covering accessories such as gas relays on oil-immersed transformers.<\/li>\n<li><a href=\"https:\/\/standards.ieee.org\/ieee\/57.106\/7750\/\" rel=\"nofollow noopener\" target=\"_blank\">IEEE C57.106 \u2014 Guide for Acceptance and Maintenance of Insulating Mineral Oil<\/a> \u2014 Moisture limits and oil condition guidance that breather maintenance protects.<\/li>\n<li><a href=\"https:\/\/standards.ieee.org\/ieee\/62\/4668\/\" rel=\"nofollow noopener\" target=\"_blank\">IEEE 62 \u2014 Guide for Diagnostic Field Testing of Electric Power Apparatus<\/a> \u2014 Field testing context for relays and insulation.<\/li>\n<li><a href=\"https:\/\/www.reinhausen.com\/en\/portal\/Portal\" rel=\"nofollow noopener\" target=\"_blank\">MR Reinhausen \u2014 Accessories and Gas Relays<\/a> \u2014 Reference documentation for premium gas relay designs.<\/li>\n<li><a href=\"https:\/\/www.osha.gov\/electrical\" rel=\"nofollow noopener\" target=\"_blank\">OSHA Electrical Safety Guidance<\/a> \u2014 Workplace safety context for working on energized transformer protection systems.<\/li>\n<li><a href=\"https:\/\/transformers-magazine.com\/\" rel=\"nofollow noopener\" target=\"_blank\">Transformers Magazine<\/a> \u2014 Industry publication with practical articles on breather and relay maintenance.<\/li>\n<\/ul>\n<h2 id=\"conclusion\">Conclusion<\/h2>\n<p>The first ones to appear on the list of low-cost and informative components that are almost forgotten about but still very necessary in an oil-filled transformer are the gas relay and the breather.
