Page 4: Overview
If the information is disregarded, the device may be inoperable or even damaged! 1 Overview The KSR-V Capacitor Protection relay has been designed to protect capacitors from damage due to over- voltage. Especially the capacitors which are used in reactive power compensation systems have to be supervised and, if the danger of capacitor damage is given, have to be shut down. -
Page 5: Measurement System
A maximum of 4 voltage channels is available. The KSR-V provides separate input terminals for the device supply voltage. It has to be connected regarding the specifications written on the type label. The supply voltage can also be connected to the power system to be measured. -
Page 6: Data Collection
The voltages can be connected directly (with respect to the maximum rating) or via transformers. In this case, a factor between 1 and 4000 can be presented to the KSR-V, which resembles the voltage conversion factor of the measurement transformers. The device will use this factor to provide corrected readings for all voltages. -
Page 7: Measured Values
Harmonics: order 2-63 for voltages UL1-3 and V1-4 3 Relays Depending on the ordered type the KSR-V is equipped with up to 6 output relays of different types (change over contacts, closing contacts). Also 4 optocoupler outputs are possible. None of the relays has any special function, they can all be used for alarm purposes (respect technical data!). -
Page 8: Alarm System
Technical Documentation Rev. 05 KSR-V – Capacitor-Bank Protection Relay 4 Alarm system The user can configure up to 32 alarms. Each single alarm continuously compares one measured value (=alarm source) to a corresponding limit value. If the trigger condition becomes true, it delivers activation signals to achieve some reaction (relay activation, display alarm). -
Page 9: Schematic Diagram
By setting a relay to “manual reset”, one can inhibit the automatic reset of the relay to the reset state when the activation by the alarms is reset. This “hold”-condition is stored in the KSR-V non-volatile memory, so it is correctly available even after supply failure. -
Page 10: User Interface
KSR-V – Capacitor-Bank Protection Relay 5 User Interface The KSR-V uses a graphical LC display with automatic backlight for showing the measurement values and the device settings. The device provides 4 keys to the user to accept any inputs. The action, a key performs, depends on the actual context and is given by small icons in the bottom line of the display. -
Page 11: Submenu "Measurement
Use keys "" and "" to select from the variety of measured values. The KSR-V stores the maxima and minima for each value. The display can be switched to show them instead of the actual value. The right key is labelled “min”, “max” or “val”, according to the selected value. -
Page 12: Submenu "Harmonics
KSR-V – Capacitor-Bank Protection Relay 5.4 Submenu "harmonics" The KSR-V calculates harmonics for all input channels. Harmonics are available in the range from the fundamental wave up to the 62nd harmonic. Both, even and odd harmonics are displayed in this submenu. If the harmonic display quotes “not available”, the voltage, which sources the harmonic calculation is below a... -
Page 13: Submenu "Setup
KSR-V – Capacitor-Bank Protection Relay 5.5 Submenu "setup" The “setup”-menu contains all settings, which can be performed by the user of the KSR-V to adjust it to certain ambient circumstances. To enter this submenu, a password is necessary. The fixed password is "2402". - Page 14 This sets the device to work with a voltage measurement transformer. Enter the transformer ratio here. If no transformer is used and the KSR-V is directly connected for voltage measurement, enter factor 1. The range is 1 - 4000.
- Page 15 "automatic reset" (relay resets automatically to inactive state if it is not activated by an alarm any more). Again, if a certain relay is not assembled in the KSR-V, the text "not available" will be displayed. To change the setting, move the arrow on the left side to this line with the ""-key...
- Page 16 5.5.5 Submenu "setupalarm" This submenu contains all settings, which have to be performed in order to use the KSR-V alarm system. The submenu contains a set of different settings, between which the user can select with the “” key. The little arrow on the left border of the display shows the selected item.

Page 17: Submenu "Device Info
This resets all relays, which are configured with the “manual reset” setting. By selection of this menu entry, the relays are set back to inactive state. A new alarm will re-activate the hold state for the relay. 5.6 Submenu "device info" This menu simply shows some information about the KSR-V device. SW: software version number ... -
