High Voltage Test on Radio

High Voltage Test on Radio: Many electrical apparatuses like transformers, line conductors, rotating machines, etc. produce unwanted electrical signals in the radio and high frequency (television band, microwave bands, etc.) ranges. These signals arise due to corona discharges in air, internal or partial discharges in the insulation, sparking at commutators and brush gear in rotating […]

High Voltage Test on Cables

High Voltage Test on Cables: Cables are very important electrical apparatus for transmission of electrical energy by underground means. They are also very important means for transmitting voltage signals at High Voltage Test on Cables. For power engineers, large power transmission cables are of importance, and hence testing of power cables only is considered here. […]
