Motor Checker ET 4P – Real-Time Operations Monitoring/Analyzing of On-line Motors

Motor Checker ET 4P can be used to detect electrical fault in the machine, without any need for dismantling the motor.

The motor checker ET 4P is a hand-held diagnostic tool that can be used to detect the condition of an electric motor. The motor checker can also help in checking the quality and condition of motors even before their installation and make the process more efficient.

The instrument can be operated in different modes to identify various types of faults, including but not limited to:

  1. Open circuits
  2. Loose connections
  3. Short circuits in a winding coil
  4. Defects in rotor bars and faulty insulation

These faults are identified all without dismounting the machine. The motor checker can also measure insulation resistance to evaluate how effective can the insulation in a machine resist the flow of electric current. In addition, it can enable early detection of inter-turn short circuit, which is a major reason for motor breakdowns.  Motor insulation is tested with a high voltage of up to 500 V DC supplied by the instrument.

The simple operation makes it the best supporting aid for electrical engineers in quick and accurate assessment of motor conditions. It is powered by 1.5V X 6AA size cells with electronic zero-set facility. With its in-built low battery indication, the engineers are promptly notified on the need to charge for seamless use.
