Solid Grounding or Effective Grounding: When the neutral point of a 3-phase system (e.g. 3-phase generator, 3-phase transformer etc.) is directly connected to earth (i.e. soil) through a wire of…
Neutral Grounding: The process of connecting neutral point of 3-phase system to earth (i.e. soil) either directly or through some circuit element (e.g. resistance, reactance etc.) is called Neutral Grounding.…
Grounding or Earthing: The process of connecting the metallic frame (i.e. non-current carrying part) of electrical equipment or some electrical part of the system (e.g. neutral point in a star-connected…
Types of Surge Absorber: The travelling waves set up on the transmission lines by the surges may reach the terminals apparatus and cause damage to it. The amount of damage…
Surge Diverter | Lightning Arrester Types: The earthing screen and ground wires can well protect the electrical system against direct lightning strokes but they fail to provide protection against travelling…
Types of Lightning Strikes: There are two Types of Lightning Strikes may strike the power system (e.g. overhead lines, towers, sub-stations etc.), namely; Direct stroke Indirect stroke 1. Direct stroke:…
Voltage Surge or Transient Voltage: A sudden rise in voltage for a very short duration on the power system is known as a Voltage Surge or Transient Voltage. Transients or…
