[{\"@type\": \"Question\", \"name\": \"What is a high voltage current transformer?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It measures circuit current at medium voltage, feeding proportional signals to protection relays and meters with insulation rated for the line voltage.\"}}, {\"@type\": \"Question\", \"name\": \"What accuracy classes are available?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"From 0.2S for metering to 5P20 for protection, per your scheme requirements.\"}}, {\"@type\": \"Question\", \"name\": \"What is the difference between metering and protection CTs?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Metering CTs prioritise accuracy at normal current; protection CTs are designed to saturate predictably under fault

{\"@type\": \"Answer\", \"text\": \"Yes, provided the outline drawing, the ratio, the burden and the terminal arrangement are matched.
