If a person receives an electric shock, it is the utmost duty of the observer to rescue the person. The first step is to disconnect the person immediately from the live supply mains by either switching off the main switch. The body should be pushed away with a dry stick or rope. If a stick is not available, then insulate yourself by standing on a dry wooden board, thick … [Read more...] about How to Rescue a Person from Electric Shock?
A ground fault circuit interrupter (GFCI or GFI) is an inexpensive electrical switchgear device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. Electric shocks can cause severe injury or even death. Even exposure to current as low as 100 ma current for only 2 seconds can cause death. GFCIs … [Read more...] about GFCI (Ground Fault Circuit Interrupter) – Working, Types, Installing and Troubleshooting
The combination of more than one conductor per phase in parallel suitably spaced from each other used in an overhead transmission line is defined as a bundled conductor. The individual conductor in a bundle is defined as a sub conductor. Bundled conductors in transmission lines are commonly used to increase electrical capacity and reduce corona and radio noise at voltages … [Read more...] about Bundled Conductors in Transmission Lines
Circuit Breaker Definition As the name indicates, the circuit breaker means the device which breaks (Open) the circuit under the abnormal condition and protects the system from hazards. The function of a circuit breaker is to isolate the faulty point of the power system in case of abnormal conditions such as faults. Keep reading to understand the working principle of … [Read more...] about Circuit Breaker Definition, Working Principle and Arcing Phenomenon
