Three phase energy meter (poly phase meter) is used for commercial or industrial application. As in industries we have huge amount of current, so to protect it we will use current transformer. It will transfer the current to isolate energy meters from high current.
The current transformers TP-23 designed for high-precision, small phase error requirements for current, power, and electric energy monitoring and metering devices. They can be used for three phase energy meter and anti-tempering electric energy meters.
