WebA megohmmeter (sometimes referred to as a "megger") is a special type of ohmmeter, which supplies high voltage to measure the electrical resistance of insulators. An ordinary ohmmeter or multi-meter is not capable of producing the required voltage and therefore cannot be used to perform this test. WebThe Temperature Dependence of Resistance formula is used to determine the resistance of a conductor at some temperature other than what is specified in a resistance table and is represented as Relectric = Rref* (1+α*∆T) or Resistance = Resistance at Reference Temperature* (1+Temperature Coefficient of Resistance*Change in Temperature).
