Difference between Current Transformer (CT) and Potential Transformer (PT)
Difference between Current Transformer (CT) and Potential Transformer (PT) Current Transformers (CT) and Potential Transformers (PT) are used to measure the current and voltage in a circuit of the order of hundreds of amperes and volts respectively. A CT has…
What is Lightning Arrester-Working Principle Diagram
Grounding wire running over the tower or substation provides good protection to the electrical system against direct lightning stroke but they fail to provide protection against traveling high voltage or current waves that reach to terminal equipment. The lightning arrester…
4 Point Starter: Working Principle ,Construction and advantages
The armature will draw a very high current due to the small resistance of the armature winding to avoid this heavy starting current 4 Point starter is used. Here we are going to discuss the 4-point starter it’s working principle and…
Types of Lightning Arresters-Horn Gap, Rod Gap, Valve Type
