Horstmann TP-1
33kV Voltage & Capacitor Tester for Euromold & NkT Connectors
Horstmann TP-I is a two-pole voltage detector according to VDE 0682 Section 415 for determination of the operating status of high voltage systems – the voltage detector is exclusively for use at capacitive LRP-test points of separable connectors:
- Euromold-angular connector with a series capacitance from 1,5pF to 3,0pF as well as
- NKT-angular connector of the types CB 12, CB 24, CB 36, CC12, CC 24 and CC 36 (all with approx. 3pF)
The Horstmann TP-I must not be applied directly at high voltage.
For testing voltage the clamp of the helix cable has to be connected with earth potential . Second the contact electrode has to be connected to the capacitive test point of the plug type cable connection.
During testing grasp only the handle of TP-I. Reaching over from the handle onto the insulated part is not allowed. Three red blinking LEDs indicate “voltage present”. This indication appears in three-phase systems in the range of 45% and 120% of rated voltage, but not below of 10% of rated voltage.
TP-I has no battery supply. During precipitation it is not allowed to use the voltage detector. Ensure that voltage detector is kept clean and dry, otherwise voltage detectors are maintenance free. TP-I must be subjected to a maintenance test according national regulations, in Germany every 6 years at the last.
