Capacitor Protection Relay KSR1

The KSR1 is a modern single- phase unbalance protection relay. Capacitors in MV or HV compensations use oil as dielectricum, which could catch fire in case of a damage. A permanent supervision of the state of the capacitors therefore is necessary. The KSR1 offers many ways to protect the capacitors against internal faults, and can warn and switch off if so required (alarm/ trip)

Highlights:

 Wide Range Power Supply

The KSR1 can be connected to any power supply from 40 to 250 VAC as well as 40 to 300V DC. It is therefore capable to work with normal mains connection or with battery power. There is no need to make a selection. By using a switching power supply, the KSR1 is insensitive to harmonic distortions.

2 Measuring inputs

The imbalance can be monitored either by using a separate current- or voltage measuring input. Permissable currents range from 20mA to 5A, permissible voltages from 0,2 to 20VAC. A wide range of typical monitoring scenarios can be covered with the KSR1.

Programmable Outputs

 Each of the 3 output relays has their own parameters. After elapsing of the programmed delay time, the corresponding relay will be triggered. After the alarm causing situation is over, the respective relay will be reset automatically or must be reset manually.

Option Modbus

Retrofitting the KSR1 with Modbus communication is very simple. A Modbus module has to be attached to the back of the relay casing and connected by cable. There is no need to exchange the entire relay if there is a requirement to integrate the KSR1 to a Modbus communication.
