MTDC and DC Systems | Control, Protection, and Study
There are several methods of control in MTDC systems. Only parallel MTDC systems are considered as these involve complexities in extending the existing control methods. The various methods suggested are…
Smoothing Reactor and DC Line | Transient overvoltages, Protection, and Effects
Introduction The smoothing reactor is connected before the DC filter and in series with the converters. Apart from smoothing the direct current, it also serves as a buffer between the…
Earth Leakage Circuit Breaker (ELCB) | Types, Working Principle, And Construction
Earth Leakage Circuit Breaker (ELCB) In industrial, commercial, and domestic buildings sometimes leakage to earth occurs. This leakage may cause electric shock or fire. Hence, leakage into the planet is…
Overvoltage Protection | Internal and External Causes Of Overvoltage
Introduction Voltages more significant than typical voltages are called overvoltages. These may affect the power system elements directly or indirectly. There are several reasons for such voltages such as lightning,…
Balanced Earth-fault Protection
Introduction of Balanced Earth-fault Protection In small size alternators, the neutral ends of the 3-phase windings are often connected internally to a single terminal. In these cases it is not…
