Oil Circuit Breaker
An oil circuit breaker is a type of circuit breaker that uses oil as a dielectric or insulating medium to extinguish the electrical arc. The
Pin Insulator
The pin insulator is used for power distribution for voltages up to 33kV. It is mounted on the cross arm of a supporting tower. The
Transposition of Conductors
Definition: The transposition process involves physically rotating the conductors so that each conductor takes up the next position in a regular sequence. This equalizes the mutual
Suspension Insulator
The main function of a suspension insulator is to separate the line conductors and support them electrically. It comprises several porcelain insulator units connected by
Armature Reaction in DC Machine
Understanding how magnetic fields interact inside a DC machine is crucial for optimizing performance and preventing losses. One such phenomenon is the armature reaction —
Fuse Wire Materials & their Properties
