Petersen coil compensation device

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-supression coil device should be adopted to prevent damages. The device is designed based on eletrical standard of DL/T620-1997 (standard of overvoltage protection and insulation co-ordination of AC electrical equipments)

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 Conditions

1.Abient Temp. of operation is between -20 centigrade and +40 centigrade

2.Relative humidity of Air is or less than 80%(+20 centigrade)

3.Altitude does not excess 2000m(If excess, pls indicate in order)

4.There is no corrosive gas around the site, so is conductive dust

6.There is no severe shocked movement around the site.
