VOLTAGE DETECTORS
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 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 piezoelectric 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.

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.

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. Spline-mounted 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 de-energized lines or apparatus.
