High Voltage Laboratory Equipments: A High Voltage Laboratory Equipments is expected to carry out withstand and/or flashover tests at high voltages on the following transmission system equipment: Transformers Lightning arresters…
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 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 Insulators: The High Voltage Test on Insulators that are normally conducted are usually subdivided as Type tests and The routine tests. Type tests are intended to…
Switching Surges in Transmission Line: Till the time when the transmission voltages were about 220 kV and below, over-voltages due to lightning were of very high order and overvoltages generated…
Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave…
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.…
