Which of the following method or technique can be used for measurement of high DC voltage?
High dc voltages are usually measured by connecting a very high resistance (few hundreds or Mega ohms) in series with a micro ammeter. Current I flowing through large calibrated resistance R is measured by Moving Coil Micro ammeter.
What is thermal breakdown in solid dielectrics?
Thermal breakdown in a solid dielectric occurs when its rate of heating exceeds the rate of cooling (1). Thermal breakdown differs from purely electronic breakdown in that the latter cannot be explained as being due to processes that are not in evidence until very close to breakdown.
