High Resistance Neutral Grounding Devices
-
HRG systems limit the fault current by placing high resistance between neutral point of transformer (or generator) and ground. As it is not possible to locate the fault point in delta connected systems, an artificial neutral point is created and delta connected system can be grounded. This allows a fault current of a few amperes thus locating the fault point gets easy. When the neutral point is grounded thru high resistance, both continuity of operation is provided during fault condition and sufficient current (typically between 2 A and 10 A) flow is provided for ease of locating the fault point.

(DCC) Resistance Bridges
-
Direct Current Comparator (DCC) Resistance Bridges. Unique innovations in 6622A design and modularity means users no longer have to decide what Bridge satisfies current requirements as well as future requirements. Optional modules allow for normal, high ohms, and low ohms measurements without having to purchase multiple bridges as per competitive products.
