Question

Topic: Lod Checking Circuits ( MW & MV ) ( Sub Staions)

Please give a descripeted definition for Differential Lod Check and provide an example.

Answer 1

Differential load checking means checking the difference between the input and output loads.That gives the input and output loads are in the same specifications or not and the loads are current stable or not. The differential load checking used for automatic checking power supplies and to ensure that the output voltage and output current are within their specifications over range of load conditions from no load to maximum load.For the example in substations the load is varries based on the consumer request.If the load increase or decrease ,they shuold provide the supply to the consumers with same specifications of power , voltage and current.At that situations they have to check the differential load,then the differential load checking gives the specifications of output current and output voltage.
