Operation of UHV Laboratory: Operation of UHV Laboratory are designed as indoor laboratories or outdoor laboratories depending on the specific requirements. An indoor laboratory is preferred when most of the…
High Voltage Laboratory Rating: The High Voltage Laboratory Rating and size of test equipment chosen in the h.v. laboratories depends on the test facilities to be provided. Normally, the design…
High Voltage Test on Transformer: High Voltage Test on Transformer are very important and costly apparatus in power systems. Great care has to be exercised to see that the transformers…
High Voltage Test on Circuit Breaker and Isolators: High Voltage Test on Circuit Breaker and Isolators is covered, giving common characteristics for both. While these characteristics are directly relevant to…
Rogowski Coil Integrator Design: If a Rogowski Coil Integrator Design is placed surrounding a current carrying conductor, the voltage signal induced in the coil is vi(t) = M dI(t)/dt where…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
Generating Voltmeter Principle and Construction: High voltage measuring devices employ generating principle when source loading is prohibited (as with Van de Graaff generators, etc.) or when direct connection to the…
Generation of Impulse Current Generator Output Waveform: Lightning discharges involve both high voltage impulses and high current impulses on transmission lines. Protective gear like surge diverters have to discharge the…
