Equipment for Japanese MarketMolding Type Earthed Voltage Transformer (EVT)
A grounded instrument transformer is a device that converts a high voltage to a low voltage and is used in connection with a protective relay or a electricity meter.
Feature
- These products can be fabricated with adherence to JIS C 1731, JIS C 1736, and JEC-1201 standards. In addition, we can alsro conform to some foreign standards.

（1）JIS and JEC standards are based on the tertiary coil of 110/3 V, 200 VA, 3G (3P) class as standard.
（2）Since EVT is are designed to connect the neutral point to the ground, be sure to ground them before use.
（3）When performing field withstand voltage tests, disconnect the terminal connection on the primary side of an EVT.
