GFCI or ground fault current interruption is a differential current protection scheme which works by comparing the difference of current between hot and neutral conductors that carry current from and to the load plugged in the receptacle. NEC defines GFCI in terms of a protection device: A device intended for the protection of personnel that … Read more
Current transformer or CT is a type of instrumentation transformer which is used to step down higher amps to lower amps. Electrical power system uses very high values of currents. It is impossible for the relays and instruments to directly monitor such higher values of currents. A current transformer is an instrumentation transformer which steps … Read more
To avoid a large number of losses, the electrical power system uses higher values of voltages. It is impractical and uneconomical to develop heavy instruments that connect directly to the power system. Measurement equipment such as relays and voltmeters used special types of transformers (namely the potential transformers) which step down the higher voltages to … Read more
Our Electrical power grids primarily consist of three-phase AC circuits. This means that all electrical components, conductors, breakers have three components. To such components and materials, we often use a single line diagram. Each line is represented by a single line instead of three or four conductors. A single line diagram reduces the complexity of … Read more
