Page 6: Application
1 Application Syscompact 2000 is a compact designed, fully enclosed cable fault location system for prelocation and pin pointing of high impedance, low impedance and intermittent cable faults of low and medium voltage cables. Easy operation and use of latest fault location methods in combination with efficient instruments enable a rapid and reliable fault location. -
Page 7: Theory Of Cable Fault Prelocation
2 Theory of cable fault pre-location At shown examples the so called test lead is already subtracted. Therefore in the left cursor (zero cursor) is located at end of test lead (= beginning of cable under test). 2.1 Echometer (Time Domain Reflection) The IRG sends a low voltage impulse into the cable under test. -
Page 8: Secondary Impulse Method
2.2 Secondary Impulse Method The IRG sends a low voltage impulse into the cable under test, it is reflected positively by the cable end. Not visible at this first measurement is the high resistive fault. A high voltage impulse released from the SSG ignites an arc at fault. - Page 9 Both curves are putted together by the IRG. At point negative reflection the location of fault is clearly visible. The distance is calculated as follows: t × Distance to fault = propagation velocity x time ...

Page 10: Impulse Current Method (Icm)
2.3 Impulse Current Method (ICM) A high voltage impulse released by a SSG to a faulty cable ignites a arc at fault position. The so created transient wave is moving between arc and connection point. The waves are picked up by the impulse current coupling SK1D... -

Page 16: Using The Syscompact 2000
4 Using the Syscompact 2000 4.1 Important notices The Syscompact 2000 should only be used to test disconnected cables. Before connecting the system, the cable has to be disconnected from the supply and the discharging/grounding has to be verified. The local legal and companies’... - Page 17 After a flashover in the cable or after interrupting the test e.g. by pressing the emergency-off button, the DUT still can carry voltage. Therefore the DUT firstly has to be discharged and afterwards grounded before handling. For correct discharging and grounding, the discharge/grounding – rod has to be connected to protection/station earth correctly.

Connecting of safety earth Connect the Syscompact 2000 with the included safety-earth-line (yellow-green) to the safety-earth-connector (B) and to the to the station earth. Use the foreseen clamps for this. For best possible earthing take care for a short connection (minimum of cable length) between safety-earth-connector and station earth. - Page 19 Please ensure that adequate precautions, as described in the chapter „discharging and grounding“ and general safety instruction are followed HV Test lead Protection earth conductor termination Syscompact 2000 sheath steady protection earth / station earth Operation of Syscompact 2000 only in vertical position!

9 Maintenance The Surge Voltage Generators SSG of Syscompact 2000 has a surge capacitor available which consists of four isolated partial capacitors. Even in the turned off condition these partial capacitors can show substantial residual charges. For safety reasons, actions which involve opening the instrument may therefore be only carried out by instructed and authorized service personnel. -
