2. Impulse Voltage Generator Impulse voltage generators are used for conducting lightning impulse tests on electric cables, capacitors, bushings, power transformers and instrument transformers. They can carry out standing lightning full wave impulse tests, chopping wave impulse tests and standard operation wave impulse tests.
    2. Capacitance and Dissipation Factor Meter This capacitance and dissipation factor meter is an up-to-date test instrument for measuring capacitance and dissipation factor (dielectric loss and impedance) for full automatically voltage devices such as transformers, cables, capacitors, insulators, HV switches, arresters, etc.
    2. Transformer Oil Vacuum Filtering Machine This series transformer oil vacuum filtering machine is a kind of typical double-stage vacuum oil purifiers and can process and recycle transformer oils efficiently under vacuum conditions. It is capable of dehydrating, degassing, as well as purifying various insulation oil utilized for high voltage transformers, circuit breakers, etc.
