Ground fault voltage relay maintenance product
Hikari Shoko Co., Ltd.
About This Product
LVG-2B/2C is a multi-circuit ground fault directional relay LDG-11/11D/11DN (discontinued product) or LDG-21B/ 21BN, and zero-phase capacitor ZPC-1A/1C, ZPC-9 (discontinued product) Or it is a ground fault voltage relay combined with ZPC-9B.
For LVG-2B/2C, input only the zero-sequence voltage (Vo). The zero-sequence voltage phase signal shaped into a pulse waveform can be distributed to the multi-circuit ground fault directional relay using the M and N terminals. At this time, up to 20 multi-circuit ground fault directional relays can be connected. Although the external shape is different from LVG-2/2S, the mounting dimensions are the same.
■Features
