Transformer Neutral Grounding Protection Capacitive Current Compensation Earth Fault Compensation System

Overview

In power system of 6-66KV, when capacitor current associated with single-phase ground fault excess 10A (cable circuit system is 30A), arc-supression coil device should be adopted to prevent severe damages.

Structure and Struture Name of the Device

1.MRD-XHZ micro-computer controller and PK screen.

2.Grounding Transformer

3.Regulated load arc supression coil

4.MRD damping resistor cabinet as well current/voltage transformer.

operation environment requirements

1. operating environment temperature range between -20°C~+40°C

2. air relative humidity ≤80%(+20°C)

3. altitude does not excess 2000m (if excess, pls indicate when ordering)

4. crrosive gas is forbidden

5. conductive dust could not exist

6. no violent vibration on site

7. microcomputer should be located in controll room of power station.Grounding transformer, arc-suppression coil and damping resistance box could be loacted outdoor or drafty room
