GM-10kV High Voltage Digital Megohmmeter

This instrument is designed for measuring Insulation characteristics of large high voltage transformers, electrical machinery electric appliance, remote power cables or buried cables, etc, solving the problem of filed interference in power plants, substations.

Note: To ensure safety, the series products must be well grounded before use
