Why is PT burden high Compared to CT burden?
The burden is the maximum load that we can connect to the secondary CT and PT. The burden of CT and PT are expressed in
What is CT Burden? CT Burden Formula
CT burden means the load connected to CT secondary. The load may be of the resistive type or of the inductive type. However, the load
Temperature Effect on Conductors, Semiconductors & Insulators
Temperature Effect on Conductors, Semiconductors & Insulators -The resistance of the conductor increase with an increase of temperature. Whereas, the resistance of semiconductors and insulators decreases
What is Leakage Flux and Fringing in Magnetic Circuit ?
Leakage flux is the flux that leaks from the magnetic circuit. All the magnetic flux produced does not flow in the magnetic circuit, and some
Difference Between Primary Cell and Secondary Cell
The main difference between a primary and secondary cell is that the primary cell is not rechargeable whereas a secondary cell is rechargeable. Primary cell
