Motor Testing
Our motor testing services ensure optimal performance, detect faults early, and extend the service life of your equipment. We perform various specialised tests to assess the electrical and mechanical health of motors.
MCCA (Motor Control Centre Assembly)
MCCA testing ensures that the entire motor control centre operates safely, efficiently, and in full coordination with the connected equipment. This includes checking the performance of starters, contactors, control circuits, and protective relays. We also verify busbar connections, cable terminations, and insulation integrity to prevent overheating, arcing, and unplanned outages in critical operations.
- Control wiring and interlock verification
- Inspection of busbar connections and torque checks
- Functional testing of protection relays and logic circuits
- Starter and contactor performance evaluation
- Breaker operation and trip mechanism verification
- Thermal scanning for hot spots
PD (Partial Discharge)
Partial discharge testing detects small electrical sparks within motor windings or insulation systems, which are often invisible to the naked eye but can lead to significant damage over time. By identifying these discharges early, we can pinpoint weak spots in the insulation and recommend corrective actions before a major failure occurs, ensuring motors remain reliable under demanding operational loads.
- Detection of insulation breakdown points
- Measurement of discharge levels and patterns
- Location pinpointing of discharge sites
- Trend monitoring for progressive deterioration
- Recommendations for rewinding or insulation replacement
Tan Delta
Tan Delta testing measures dielectric losses in motor insulation to evaluate its health and predict remaining service life. A rise in Tan Delta values indicates possible moisture ingress, contamination, or insulation ageing. This test is especially useful for high-voltage motors where insulation breakdown can result in costly downtime and repairs.
- Measurement of insulation loss factors
- Identification of moisture or contamination issues
- Voltage-dependent dissipation factor measurement
- Comparative analysis with historical test data
- Predictive maintenance recommendations
RLA (Rated / Running Load Amps)
Tan Delta testing measures dielectric losses in motor insulation to evaluate its health and predict remaining service life. A rise in Tan Delta values indicates possible moisture ingress, contamination, or insulation ageing. This test is especially useful for high-voltage motors where insulation breakdown can result in costly downtime and repairs.
- Measurement of running load current under normal operation
- Comparison against manufacturer-rated RLA
- Identification of overload conditions
- Detection of phase imbalance or poor power factor
- Recommendations for load balancing or mechanical inspection
