2 Application
The most of the high- and medium voltage capacitors use oil as dielectric, which can catch fire in case of a failure. For
this reason, it is recommended to monitor capacitor banks during operation, in order to detect failures earlier.
Using the KSR1, there are two possible ways to set up a monitoring system. Here, either an unbalance current or an
unbalance voltage can be measured to detect a faulty capacitor bank.
2.1 Monitoring unbalance voltage
2.2 Monitoring unbalanced current
