Page 4: Intended Use
Dipl.-Ing. H. Horstmann GmbH Instructions for Use Intended Use The ComPass B is used in medium-voltage distribution networks and combines the functions of a directional short-circuit and directional earth fault indicator. It has been developed and designed • to detect short-circuits and earth faults •... -
Page 5: Hr-Interface Cable Set
VDE 0682 Part 415 standard (IEC 61243-5) for capacitive voltage detecting systems. Besides their main function, WEGA 1.2 C and WEGA 2.2 C, respectively, can provide the tapped capacitive voltage to the ComPass B in order to measure and detect the fault direction and load flow. -
Page 6: Device Functions
The instrument measures permanently the phase voltages and currents taking these values as a basis for real time calculations of the neutral point displacement voltage V and earth fault current Based on these values the ComPass B is able to detect faults in medium-voltage networks and also to determine their characteristics. Figure 9:... -
Page 7: Fault Direction
In some cases it is not possible to determine the direction of a fault, especially when the fault is located close to the switchgear unit the ComPass B is installed into. In such cases the ComPass B signals an error without directional indication. -
Page 8: Voltage Ring Buffer
If there is a small distance between the location of the fault and the place of installation of the ComPass B unit, the phase voltages of the affected phases may become too small to be usefull for the decision of fault direction. For this reason, the Compass B is provided with a ring buffer. The measured values of all phase voltages are permanently written into this buffer. -
Page 9: Reset Modes
If a relay is configured for momentary contact it will engage for 1s for every fault assigned to it, whereas, if it is configured for permanent contact, it will remain engaged as long as ComPass B is indicating the fault. If a second fault occurs, it will disengage for 1s and then re-engage. -
Page 10: Operator Control
Multicolour LED The multicolour LEDs signal different operating conditions of the ComPass B (see Table 1). In par- ticular when the OLED display is not illuminated, the LED gives advanced information that can be investigated in more detail by the user via the OLED display. -
Page 11: Power Supply
The ComPass B is a MODBUS Remote Terminal Unit (RTU) Slave. 3.3.3. Digital inputs/outputs The ComPass B is provided with 4 digital (relay) outputs and one digital input. Each relay output can be assigned with individual functionality either via the front panel control or the RS485/MOD- BUS interface. -
Page 12: Test Mode
• external input contact During test mode, the ComPass B controls both its electronics and its software. The yellow light of the multicolour LED starts flashing to indicate the test mode. If an error is detected on the device, the multicolour LED flashes yellow, either in a double or triple flash mode which depends on the type of error. - Page 13 Dipl.-Ing. H.

Dipl.-Ing. H. Horstmann GmbH Instructions for Use 4.4. Electrical connection 4.4.1. Terminal strips The terminal strips are located in the rear wall of the instrument. If provided on the side of the switchgear, perform electrical connection according to the following terminal reference list (See also circuit diagram on the top side of the instrument, numerical arrangement from right to left). -
Page 15: Device Configuration And Commissioning
5.1. Device configuration ComPass B is delivered with a standard factory setting (see Appendix A) which, in most cases, meets all requirements. Some parameters (see Table 5) however need to be set and checked indi- vidually which can be carried out either via the front panel control or the RS485/MODBUS interface. -
Page 16: Voltage Calibration
5.2. Voltage calibration Step 1: Voltage calibration is required after ComPass B has been installed in the switch-gear and the switch-gear has been energised. Below voltage calibration is carried out using the example of a 11 kV network. Step 2: Voltage calibration is possible only, if medium voltage is applied to the switch-gear. - Page 17 Dipl.-Ing. H.
