1-1 Overview
The K7GE-MG is a device that automatically measures the insulation resistance of a load and supports
trend monitoring.
Periodic inspections by manpower may cause a unexpected machine stoppage due to a decrease in
insulation resistance of equipment before the next inspection. The K7GE-MG provides automatic
monitoring of the insulation resistance of each load and allows planned maintenance.
The K7GE-MG measures the insulation resistance by the same detection principle (Megger method) as
a Megohmmeter.
To measure the insulation resistance using the K7GE-MG, it is necessary to
combine one Main Unit with at least one Probe Unit.
The functions of the Main Unit and Probe Unit are
shown in the figure on the right.
The Main Unit corresponds to a Megohmmeter,
and the Probe Unit corresponds to a
measurement probe with internal contacts. The
Main Unit turns ON these contacts in sequence
and measure multiple loads individually.
Up to eight Probe Units can be connected to one
Main Unit.
K7GE-MG supports a motor as a measurement load. If you want to measure other loads such as a
heater or transformer, carefully study the operating specifications of the K7GE-MG before use.
