Electrical Transformer Protection
High impedance: In the High impedance differential relay the simple current or voltage based operated relay can be use as High impedance with the series of stabilizing re ... See More
The principle of differential busbar protection is very simple. Here, secondaries of CTs are connected parallel. That means, S1 terminals of all CTs connected together an ... See More
In the High Impedenc DPR the Protection relay will have only one summation current input and it will pick up based on the difference in the current sumation.
The Relay which is used to protects the Bus Bar in the substation is called Bus Differential Relay. This relay acts on Differential current measurement principle. As per ... See More
