MOTOR CHECKER EMC - 25 Fast Checks of On-Line Motors EMC-25 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-25 will immediately detect it, without having to dismantle the equipment.
The EMC-25 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. Technical Specifications
