Should pay attention to when deactivating voltage transformers - News - Global IC Trade Starts Here.

inductance

(1) The protection and automatic device of the components of the secondary circuit of the voltage transformer should be considered first, and the influence on the metering meter should be taken out, and the protection and automatic device that may be malfunctioned are taken out of operation. And record and calculate the amount of electricity.
(2) If there is an automatic or manual voltage switching device, the protection and automatic devices of the components it carries may not be taken out of operation. But make sure the switch is reliable.
(3) When the voltage transformer is deactivated, both sides of the high and low voltage should be disconnected.
