HM2672 Anti-interference megohmmeter insulation test meter is research and manufacture to solve the evaluation of electrical insulation quality of HV transformers, motors, generators, long-distance high-voltage cables, tubular busbars, etc. under strong interference from high-voltage substations and power plants. It is especially suitable for large-capacity over 110kv Test site with strong sexual interference.
The meter has the function of measuring separately, measuring absorbing ratio and polarization index, and can measure each value at one time. It is a kind of insulation resistance measuring instrument with convenient use, comprehensive function and wide measuring range.
