High-voltage detector HVP-275

​The TECPEL HVP-275 is a high voltage proximity detector.It has eight voltage detection settings from 240Vac to 275kVac. The HVP-275 consists of an internal pickup sensor plate, a sensitivity selector, a visual, and a sound annunciator. With the HVP-275, physical contact with electrical conductors is not necessary when testing for live lines. This tester works by proximity. Its sensor senses the radiated field which surrounds live conductors. Radiated field strength increases with voltage and decreases quickly with distance or earth shielding. The radiated field from a cable of closely bunched conductors supplied by three-phase power tends to cancel (See “Limitations of use” paragraph). The detecting distance of a 250Vac single live wire is approximately 10cm. With a bunched neutral and earth cable, as in a flexible cable, the distance is reduced to 5cm.
