1.Steplessly and continuously adjustable 2.Dynamic compensation
1.Purpose:
This product is used in 6KV~66KV systems whose neutral point is ungrounded to limit the arcing currents during ground faults.
2.Features:
2.1 full-statically structured free of any movable components inside
2.2 Compensation response speed is not higher than 20ms
2.3 Electric control is steplessly and continuously adjustable
2.4 Automatically track and scan the neutral voltage and capacitance current
2.5 Compensation current allows an extensive regulation range, ratios of both upper and lower limits reach to 6-10 times
2.6 Dynamic compensation, no damping resistor is required
2.7 Automatic or manual switch-over
2.8 Allowable configuration of 422/485 serial interfaces as required by the user
2.9 Single-phase grounding line selection unit is optional for the device to monitor multiple feed branches
