Return Cables Continuity Tester TCK-2
- Testers and Measuring Instruments
Return cable continuity tester TCK installed in the traction substation monitors the resistance of the circuit consisting of: substation earthing resistance, rail to earth resistance and return cables resistance.
When measured resistance exceedes the threshold value either a notification or powering-off a substation is initiated depending on the value of the resistance. In most practical situation, too high resistance indicates broken return cables.
Together with voltage limiting device VLD connected in parallel establishes complete earth fault protection system in substations or sectioning cabins.
