Load bank develops electrical load, applies the load to the electrical power source and dissipates the resultant power output from the source. Load bank accurately mimics the operational load that a power source will see in actual application. It is a self-contained, unitized, systematic device for developing electrical load and applying the same to an electrical power source for converting or dissolving the power output. The load bank is used in UPS system testing, testing the functioning of turbines, Battery system testing, load optimization in heavy duty power applications, factory testing of engine generator sets, To reduce "wet stacking" problems etc. National Resistors offers load banks and auxiliary equipment necessary to handle these applications.

Neutral side cubicles are best suitable enclosures for installation of Neutral grounding transformer (NGT) and Neutral Grounding Resistance (NGR). The Neutral side cubicles protects of the generator. These cubicles are available in configurations and specifications as per the application, demands.

Phase side cubicles offered are made as per the application it is put to. These cubicles feature effective functioning and require very low maintenance. The design of phase side cubicles depends on voltage level of the generator and the type of bus duct system between generator and step up transformer of the power plant. The phase side cubicles undergo functional testing of the complete assembled panel; continuity test and test on wiring; and the HV test, to ascertain their compliance to performance & safety standards.
