Category "S" for switchgear and overhead lines.

Category "S" for switchgear and overhead lines.

The nominal voltage selector switch allows to switch between three voltage ranges. For safety reasons, the voltage detector can only be switched on if the selector switch is switched to the most sensitive range of 3 kV to 10 kV. The switch snaps into the relevant position and provides protection against inadvertent switching. A magnetically operated, wear-resistant reed switch changes the switching position.

Category "S" for switchgear and overhead lines.

For three-phase systems and single-ended monophase switchgear installations.

Special features of the switchable voltage detector:
The selector switch can be moved into three positions for the relevant voltage and frequency ranges:
3 ... 10 kV / 50 Hz – three-phase systems
6 ... 20 kV / 50 Hz – three-phase systems
6 ... 20 kV / 16.7 Hz – single-ended monophase systems
For safety reasons, the detector can only be switched on if the selector switch is switched to the most sensitive range of 3 kV to 10 kV / 50 Hz. The switch snaps into the relevant position and provides protection against accidental switching. A magnetically operated, wear-resistant reed switch changes the switching position.

For single-ended monophase switchgear installations and point heating systems.

For traction power lines.
Hook-shaped electrode and end fitting with plug-in coupling and non-slip eye included.

Use for traction power lines
Voltage detectors for traction power lines have a shorter extension than voltage detectors for overhead contact lines. To ensure reliable indication, the PHE 15 16.7 BEL STK voltage detector may only be used for traction power lines and not for other components of overhead contact lines. Moreover, it must not be used from ladder trolleys for overhead contact lines.
Traction power lines are supply lines, line feeders, bypass lines, connecting lines, feeder lines, 15 kV cables, cable sealing ends, switch lines and transverse switch lines.
