10-30 kV Pole Phase Comparator

For use on any grounded electrical system, DETEX Voltage Detectors are available in seven models that cover a range from distribution class to transmission line voltages up to 550 kV. Biddle offers six electronic "beeper" models and one model with LED indication for greater visibility when testing indoors.

The analog testers are ideally suited for outdoor testing of grounded and ungrounded systems, especially in areas where an LED lamp is not easily visible. The large, 3.5-in. (89-mm) analog scale is calibrated to indicate the presence of nominal system voltages; the tester cannot be used to determine an exact voltage measurement.

The testers are equipped with two fixed-length poles connected by a flexible, insulated cable. Hand guards ar e standard on lower voltage models, while units for use on higher voltages are fitted with a universal spline mount for attachment to a standard hot stick. Spline-mounted testers provide a 10-ft (3-m) nominal spacing between two energized phases.

The Phasing T ester (cat. no. 510836-1) pr ovides bright LED indication for easy visibility indoors or where lighting conditions are poor. Approximate voltage ranges to be checked can be preset for additional assurance. The instrument consists of a pair of fixed-length, 43-in. (1092-mm) poles with hand guards. A flexible, insulated connecting cable is capable of covering a 7-ft (2.1-m) span between two ener gized phases under test.
