Condition Monitoring System
Now, the question arises that how we can monitor or foresee faults?
The first basic rule is to apply the pro-active approach to maintenance. The pro-active maintenance applies with physical inspection and with the help of performing periodic maintenance to determine any damaged or defective parts. Accordingly, the inadequate parts will be replaced before a major breakdown happens. It’s a little risky because periodic maintenance is planned as per the time specified, but over time, the generator and motor’s part’s condition remain deteriorated.

Condition monitoring is an advancement to know the health, safety, and performance of generators and motors where reliable, continuous, and efficient operations are required. There are two types of monitoring systems, the first one is offline monitoring and the second one is an online monitoring system. In this monitoring technique, different parameters are measured, transmitted, and monitored in the control station where the operator is aware of the working conditions of the generator and motor.
The condition monitoring system is more important for high rating generators which are connected to the national grid where continuous operation is required. Because any voltage or frequency fluctuation can cause a total blackout in the whole country in the worst scenario. For this reason generator frequency, current, voltage, MVAR, winding temperature, bearing temperature, bearing vibration, lube oil levels, lube oil pressure, etc. needs to be measured, watched, and monitored continuously. Similarly for heavy-duty motors, bearing temperature, vibration, and cooling oil /or mechanism; needs to be monitored continuously. Online condition monitoring system is used where sensors measure the desired readings, convert those reading into signals which are transmitted to dedicated software which displays the values in the graph, numeric and in the bar as per requirements.
Condition monitoring solutions are critical to the performance of your motors and generators. In many industries, these systems provide an early warning for potential breakdowns or failures before they happen. High-tech condition monitoring solutions help minimize downtime and maintenance costs. There are effective ways to find and choose the right solution for your needs that won’t break the bank.

Figure 1 and 2 display the trends of current and active power parameters of 14V001 equipment which had failure on stator windings on 21 November 2014. On November 21, 2014, the equipment with failure was sent to rewind the stator winding and it was recommissioned on 22 November 2014. Until 25 November 2014, an increase was observed in the current drawn by the rewinding motor. The customer was asked whether the load of the motor was changed by the operator and learned that no changes were made to load. After detailed inspection, it was realised that there was an error in the rewinding process and equipment has drawn more current than expected. The equipment rewinding has replaced with spare motor and the current values were observed again.As can be seen on Figure 2, there was a decrease in current values. In the event that the equipment that was rewinding was operated in this condition, an energy loss of 61320 kWh / year would have occurred.
