DESCRIPTION
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. Megger offers six electronic
“beeper” models and one model with white LED indication for greater
visibility when testing indoors.
The beeper-style electronic detectors provide audible and visual
indication of the presence of phase-to-ground ac voltages, in
accordance with ANSI C84.1-1982 standards.
The 6.9-kV model is equipped with a telescopic pole. All other models
are fitted for universal spline mounting on a hot line pole rated for the
voltage of the system being tested.
Electronic voltage detectors for use on distribution line voltages (Cat.
No. 514360-1 series) provide a single red LED.
Detectors rated for transmission line voltages (Cat. No. 514242 series)
provide four LEDs for improved visibility at greater distances.
The white LED-indicating voltage detector is designed for indoor
testing of grounded ac systems. A row of bright LED indicators
provide easy visibility in poor lighting conditions. During testing,
the presence of voltages within the detector’s operating range will
illuminate the bright LED bulbs.

A built-in piezo electric voltage source provides a test feature to ensure
that the detector is operative before use. A pushbutton activates the
self-test.
The detector is equipped with a 48-in. (1219-mm) telescopic pole
calibrated and marked for voltages within the ratings of the detector.
These demarcations assist the user in adjusting the pole to the length
required for safe operation. The pole retracts to 34 in. (864 mm) for
convenient storage in a vinyl carrying case when not in use.
APPLICATIONS
All DETEX models provide continuous monitoring with no on/off
switch. They respond to minimum phase-to-ground voltages as
outlined by ANSI C84.1 standards, with conformance to IEC guidelines
for capacitive high-voltage test instruments.
Prior to testing, a self-test may be activated on the electronic detectors
at the push of a button. The test simulates application of external
voltage to the probe electrode, which verifies the operation of the
buzzer and lights a red LED.
When the TEST button is released, a green LED indicates the
detector is operative and ready for use. If voltages within the
detector’s operating range are present during testing, the green LED
extinguishes, the red LED flashes and the audio tone sounds until the
detector is removed from the voltage source.
FEATURES AND BENEFITS
Available in seven models covering a range from distribution class to
transmission line voltages up to 550 kV.
Six electronic, beeper-style models and one model with white LED
indicators for ease of use.

PHASING TESTERS
DESCRIPTION
DETEX Phasing Testers are available in five models for applications up
to 69-kV class systems. The models include four analog phasing testers
and one model with LED indication.
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 are 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. Splinemounted testers provide a 10-ft (3-m) nominal spacing between two
energized phases.
The Phasing Tester (Cat. No. 510836-1) provides 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 energized
phases under test.
APPLICATIONS
These two-pole phasing testers may be used on grounded and
ungrounded ac systems to check high-voltage fuses, test for correct
phase connections and test for the absence of high voltage on deenergized lines or apparatus.
FEATURES AND BENEFITS
Used on grounded or ungrounded ac systems to check high-voltage
fuses, test for correct phase connections and test for the absence of
high voltage on de-energized lines or apparatus.
Five models available for up to 69-kV class systems.
OPTIONAL ACCESSORIES
PIEZO VERIFIER
This essential safety tool is used to confirm the correct operation of
voltage detectors and phasing testers that do not have a self-testing
capability. When the verifier handle is depressed at the rate of 3
strokes per second, a piezo crystal generates approximately 1800 volts.
This voltage, when applied to the tip of the detector, tests for integrity
of the current path and proper operation of the indicators.
A high-voltage model provides selectable outputs of 10, 20, and
30 kV.
A three-step procedure of testing the detector with the piezo verifier,
using the detector to test for the absence of high voltage and then
testing the
detector again
should be strictly
observed in
accordance
with accepted
operating
procedures. Verifier can be used with single- and two-pole models.

PNEUMATIC GLOVE TESTER
This rugged, molded air pump conveniently tests all types of rubber
gloves with a cuff diameter of 5 in. (127 mm) or less. A built-in check
valve retains pressure within the glove as long as desired. Tester is
provided with two fabric-covered elastic sealing rings.
