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
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. Keep reading to understand the working principle of the circuit breaker. The function of a circuit breaker is to isolate the faulty point of the power system in case of abnormal conditions such as faults. Different … [Read more...] about Circuit Breaker Working Principle and Arcing Phenomenon
