The instrument can also test the CVT ratio and voltage angle difference. It can accurately measure the dielectric loss and capacitance of CVT without dismantling the CVT high voltage lead.High speed sampling signal: The inverter and sampling circuit of the instrument are all controlled by digital, and the output voltage is adjustable continuously.Multi protection security: The instrument has many protection measures, such as input voltage fluctuation, output short circuit, over voltage, over current and temperature. The instrument also has the grounding detection function to ensure that no grounding equipment is not allowed to boost
