Power Distribution Equipment

Overview

In power system of 6-66KV, when capacitive current associated with single phase ground fault excess 10A (It is 30A in 6-10KV cable circuit system), arc suppression coil device should be adopted to prevent arc grounding, remove earth fault and improve power supply quality.

MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation Device employs standard industrial computer system, bus-organization, multilayer PCB and full-color LCD screen to provide system with stable operation, visual display, strong anti-interference capability, perfect parameter settings and information query function.

MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation Device adopts 6-110KV voltage grade and is widely used in transformer substations of large factories and mines.

Features
1. Controller adopts industrial computer platforms, dual-CPU framework and multilayer PCB processing to ensure stable and reliable operation
2. With full-color LCD screen, the running state, system capacitive current, neutral voltage, neutral current, out-of-resonance degree, residual current and fault-times of single-phase can be displayed, set and inquired conveniently
3. The adjusting range is wide, between 0-100% rated current and also accurate and quick
4. Embedded high voltage grounding line selection module employs residual incremental method and active power method making the line selection accurately and quickly
