Modern electrical power measurement and analysis needs are different today from the needs over a decade back. Modern electrical equipments use a variety of methods to achieve higher efficiencies of operation. These techniques distort the current drawn from the mains supply. Accurate measurement of power under complex waveform conditions impose a difficult task on modern power analyzers.

Voltech Instruments, U.K. has been worldwide leaders in this area of power measurement and analysis.

Increasing use of electronic and electrical goods have spawned major supporting manufacturing industries that specialize in the production of large volumes of intermediate components such as transformers of all shapes and sizes to suit a range of applications.

Traditional methods of testing the transformers during manufacture for it rated specifications is generally time
