ABSTRACT
THE INVESTIGATION OF ELECTRICAL SIGNATURE ANALYSIS METHOD IMPLEMENTATION
FOR THE MONITORING OF SAFETY MOTOR COOLANT PUMP IN PWR.The monitoring for the
safety of motor coolant pumps for the PWR can be very essential even though they have been designed
considering high safety technology and reliability. To monitor the safety of the motor coolant pump, one of
the advance techniques is using electrical signature analysis, known also as motor current signature analysis.
This research demonstrates the investigation of electrical signature analysis technique in order to obtain
accurate safety analysis results. Crucial aspects are discussed in this paper, such as data acquisition set-up,
characterization of motor coolant pump and the example for fault detection utilizing 2.2 kW induction motor
to simulatethe reactor motor coolant pump. The motor characterization results the identification of slip
motor between 0-4 Hz, fundamental frequency of stator current at 50 Hz, rotor frequency at full load around
23.5 Hz. In addition, the eccentricity of stator and rotor faults can also be identified using the existence of
frequencies of the rotor slot harmonic and the sideband of fundamental frequency of stator current affected
by rotor frequency at 26.5 Hz and 73.5 Hz.
