Fast Checks of On-Line Motors:
EMC-22 is a portable diagnostic tool for Electrical Engineer and is used for quick on site checks of
electric three-phase machines.
A reduction in machine performance, such as inefficient operation or tripping of overloads, may indicate
mechanical or electrical faults. If the fault is electrical the EMC-22 will immediately detect it, without
having to dismantle the equipment.
The EMC-22 may also be used to check quality and condition of motors which have been in storage
before they are installed.
The instrument has three separate operating modes to measure different types of fault like fully
insulation, open circuits / loose connections, short circuits and rotor defects. Motor
insulation is tested with a high voltage of 500V DC supplied by the instrument.
