Megger DETEX® Voltage Detectors Tests Grounded AC Systems
For use on any grounded electrical system, DETEX Voltage Detectors 514360-1 514360-2 514360-3 514360-4 514242-1 514242-2 514440-2 are available in seven models that cover a range from distribution class to transmission line voltages up to 550 KV. MEGGERoffers six electronic "beeper" models and one model with neon 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 514360-1 6.9-KV model is equipped with a telescopic pole. All other models,514360-2 514360-3 514360-4 514242-1 514242-2 514440-2, 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 neon-indicating voltage detector is designed for indoor testing of grounded ac systems. A bright neon indicator provides easy visibility in poor lighting conditions. During testing, the presence of voltages within the detector’s operating range will illuminate the bright neon lamp. A built-in piezoelectric voltage source provides a test feature to ensure that the detector is operative before use. The self-test is activated by a pushbutton. The neon 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.
MEGGER 514360-1 has Telescopic Pole for Safety
The DETEX 514360-1 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.
Visually Alert Bright LEDs Indicates Presence of High Voltages

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 detectors operating range will illuminate the bright LED bulbs
Fail-Safe Prior Test Insures Proper Operation of DETEX Models DETEX Voltage Detectors 514360-1 514360-2 514360-3 514360-4 514242-1 514242-2 514440-2
A built-in piezo-electric voltage source provides a self- test feature to ensure that the detector is operative before use. A pushbutton activates the self-test. 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 detectors 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.
Fail-Safe Tester for Voltage Detectors that Lack Self-Test
Megger Piezo Verifier 510006
This MEGGERMegger Piezo verifier 510006 is an essential safety tool. This MEGGERMegger tester is used to confirm the correct operation of voltage detectors and phasing testers that lack a self-testing capability. When the verifier handle is depressed at the rate of 3 strokes per second, the piezo crystal generates a safety check charge-voltage. This voltage, when applied to the tip of the detector tests for proper operation of the indicators. The Megger 510006 Piezo Verifier can be used with single and two pole models. It confirm the correct operation of voltage up to 30 KV, Generates 10KV, 20KV, and 30 KV is a small compact self powered Handheld tester.
DETEX Models Feature Calibrated Telescopic Pole
The DETEX 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.
DETEX Safe Continuous Monitoring of Phase-to-Ground Voltages
DETEX models 514360-1 514360-2 514360-3 514360-4 514242-1 514242-2 514440-2 provide continuous monitoring of minimum phase-to-ground voltages as outlined by ANSI C84.1 standards, with conformance to lEC 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 detectors 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.
