Capacitor Protection Relay KSR

7 Measurement channels

There are 3 voltage- and 4 current measuring channels in the KSR, so the range of possible connections for monitoring capacitors is very versatile.

Sophisticated Measuring- and Monitoring System

The measurement system of the KSR offers a total of seven input channels (3 for voltage, 4 for currents). The Ct ratio is programmable in a range of 1 – 10000. Current input 1 to 3 shares the same Ct ratio, whereas channel 4 can be programmed with a different Ct ratio.

In total there are 32 protection settings available. Each of the settings can be programmed by the operator in following way:

• Monitored value (source)
• Trigger (measured value is larger or smaller than threshold)
• Threshold (limit)
• Time delay when violating threshold (T-ON)
• Time delay after end of threshold violation (T-OFF)
• Output selection (relays to be activated in case of violation)

A total of 6 relais are available for alarm signals, among them 2 c/o and 4 n/o relays. These relays can be “or” linked so that they are dependent on several alarm conditions. In addition to the alarm-relays, also alarm- messages can be displayed on the LCD display.
