Voltage detectors
TP-I
The TP-I device is a two pole tester for capacitive test points on connectors in medium voltage switchgears with coupling capacitors of 1.5 to 2.5 pF. This device determines the operating conditions of high voltage installations according to EN 50110-1 (DIN VDE 0105 Part 1 and 100). This device does not have a built-in power source (battery) and thus no self-test function.
For transportation purposes, the insulating element can be removed from the display unit with the contact electrode.
According to the German accident prevention standard DGUV Regulation 3 (Table 1c), the device is subject to maintenance tests with minimum intervals of at least 6 years.
- Design based on IEC 61243-1 (VDE 0682-411), Category S
- For dry conditions
- Optical voltage indication
- No battery
