Zhengzhou which uses three 1,600 kVA transformers operating at an average load factor of 92 percent for twelve consecutive hours. A Tuesday afternoon power disturbance on the utility feed results in a voltage decline at the facility for 400 milliseconds, with three servo-controlled packaging systems stopping simultaneously. Production ceases for 47 minutes while equipment operators reactivate drives and PLCs, resulting in approximately $18,000 in revenue loss, along with the destruction of two production runs. The investigation conducted by the maintenance supervisor confirms the suspicions raised around the power transformers that were worn down over six years from the installation.
