High Voltage Testing Market : Overview The availability of electrical energy is vital for the economic development and quality lifestyle. Any electrical equipment must be capable of withstanding over-voltages during the operation. This can be assured by suitable testing techniques and testing equipments. High voltage testing can be broadly classified into tests on completed equipment and on insulating materials. The tests carried out on sample of dielectric consist of measurement of dielectric loss per unit volume, dielectric strength of the material and permittivity. Test carried out on completed equipment are the measurement of capacitance, power factor, ultimate breakdown voltage and flash over voltage. The break down voltage test on completed equipment is only done on a few samples since it permanently damages and destroys the equipment from further use. Breakdown voltage equipment is subjected to withstand test on which the voltage applied is about twice the normal voltage....
