AC DC Test Sets, we offer are functional as the air-insulated high-voltage models. These are appreciable for their advanced performance as well as long-term reliability. The provided solution are accessible with maximum operator safety. These are functional as the highly portable and dependable DC high voltage sources that can examine the quality of motors, switch gear, electrical power cables, transformers, insulators, and capacitors. AC DC Test Sets are included with general-purpose ac high-voltage sources. These are apt for the testing of several varieties of electrical insulation. In addition, these allow for protected leakage current measurements. Also, these are suited for their use with dissipation and capacitance factor bridge systems for enabling the measurement of insulation power factor.
