Earth fault directional relay Zero-phase capacitor
Hikari Shoko Co., Ltd.
About This Product
ZPC-9B uses a combination of three insulator capacitors EPD-2A and a transformer CF-71A to detect zero-sequence voltage and supply it to the ground fault direction relay LDG and voltage relay LVG, eliminating unnecessary operations. Provides stable high-voltage ground fault protection. EPD-2A is a voltage divider (PD) with a high-voltage ceramic capacitor built into an indoor epoxy insulator, and satisfies all JlS performance conditions as a support insulator.
ZPC-9B is not compatible with LDG-13 series and LVG-2 series (excluding LVG-2B).
■Features
・This is an insulator type capacitor that detects ground fault voltage.
- Consists of insulator capacitor EPD-2A, transformer CF-71A, and shielded wire CF-89.
・Used with LDG-73, LDG-83 or LVG-7, LVG-8.
