Low-Impedance/High-Impedance Earthing

The Symmetra® MW is easily integrated into either a solid grounded system, or a high-impedance grounded system.

In a solid grounded system, the neutral power source (mains, generator, or UPS) is solidly grounded. In the event of a down-stream ground fault, the fault current will have a path back to the source, and the over-current device feeding the faulted part of the installation will trip and isolate the fault.

In a high-impedance grounded system, the source is grounded with an impedance (grounding resistor). In the event of a down-stream fault, the fault current will be limited by the impedance of the grounding resistor. The value of a high-impedance system is its ability to maintain operation with a given system fault to ground, i.e. the over-current device will only trip at line-to-line faults or double ground faults. For a high-impedance system to provide enhanced power system reliability and availability, a ground-fault monitoring/alarm system is required.

Grounding electrode conductor to be supplied by the customer.
