Product description

Limiting fault currents becomes very important at protecting generator windings. For that reason we are manufacturing generator neutral grounding resistor panels limiting fault current to 10 Ampere value.
By limiting fault current damage at the fault point is also reduced; therefore, maintenance and repair costs are reduced.Since the ground-fault current is smaller and controlled, ground-fault relaying still has the requirement of fast tripping. Also better time current coordination can be achieved.

Advantages of limiting the current by Generator Neutral Grounding Resistor:

To reduce burring and melting effects in faulted electric equipment, such as switchgear, transformers, cables and rotating machines.
To reduce mechanical stresses in circuits and apparatus carrying fault currents.
To reduce electric-shock hazards to personnel caused by stray ground-fault currents in the ground return path.
To reduce the arc blast of flash hazard to personnel who may have accidentally coused or who happen to be in close proximitly to the ground fault.
To reduce the momentary line-voltage dip occasioned by the clearing of a ground fault.
To secure control of transient overvoltages while at the same time avoiding the shutdown of a fault circuit on the occurrance of the first ground fault.
