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.)…
High Voltage Testing of Surge Arrester: In modern practices, surge arrester or lightning arresters are the most reliable apparatus to protect the power system against transient voltages due to lightning…
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…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation…
Schering Bridge Theory for Three Terminal Measurement: For two terminal measurements the bridge is grounded at its junction points. The supply transformer, detector, and all the components of the bridge…
High Voltage Schering Bridge: In the power frequency range (25 to 100 Hz) High Voltage Schering Bridge is a very versatile and sensitive bridge and is readily suitable for high…
Direct Current Resistivity Method: The specimen shape and the electrode arrangement should be such that the Direct Current Resistivity Method can be easily calculated. For a solid specimen, the preferable…
