• Constant controlling of current flowing on earthing
• Measurement with the use of a single clamp or two clamps simultaneously. In the case of using two clamps, the current value is summed up, which allows for checking twin pylons (rotational), with an independent clamp for each component pylon
• Work mode LED indicator

MPU-1 is dedicated to controlling (measure) leakage current in AC, low and medium voltage power networks. It is designed to make measurements, which results define the network's safety condition for leakage current. The device enables to set a limit for the maximum safe value of flowing leakage current and for values above this limit, a visual and sound alarm is activated.
