This is my 3rd project where in i'm commissioning a Shunt reactor protected with High Impedence Differential Protection ( rating 125 MVAr). I couldn't get a convincing answer as to Why are Shunt Reactors protected with High Impedence Differential Protection? Why not Low Impedence differential...
The requirement to have High Impedence Differential protection is to have CTs at both the sides of the protected equipment with same CT Ratio and Magnetising Characteristics.
But have anyone of you seen it otherwise? ie, CT with same ratio but different magnetising characteristics.
If yes. What...
Hi all.
I have a few fundamental questions on Auto-Transformers .
1. Apart from the mechanical support, what exactly is the role played by the Core in an Auto-Transformer? In case of a 2 or a 3 winding transformer, the core provides the magnetic path which is not required in case of a...
