VTE / VTM / POWER LIGHT / VTO / PEKE / VTC voltage detectors 1–79 kV AC and 0.5–5 kV DC

Country: Spain · Model: VTE / VTM / POWER LIGHT / VTO / PEKE / VTC

The VTE, VTM, POWER LIGHT, VTO, PEKE and VTC series voltage detectors check for absence of voltage in AC networks from 1 to 79 kV and DC networks of 500–5000 V before earthing is applied. The detector is fitted through a universal head on an insulating stick of the appropriate class, and the electrode is brought to a busbar, wire, cable or equipment terminal.

VTE-U / VTE-P / VTM: electronic contact type, ranges from 3–10 to 22–66 kV (VTM), 5–35 / 5–66 kV (VTE); IEC 61243-1
Indication: red LED and powerful buzzer – voltage present, green LED – voltage absent, orange – low battery
VTE/VTM/VTA power supply: 9 V 6LR61 battery, sleep mode < 1 µA after 2 min
POWER LIGHT: detector with built-in torch, from 1–3.3 to 22–79 kV, 360° LED, 2 × AA

Description

The electronic VTE (external VTE-U and VTE-P with a stick) and VTM have a microcontroller and contact detection, so the indication stays correct even under the influence of fields from neighbouring phases. Presence of voltage is shown by a red LED and a powerful audible signal, absence by a green LED, and a low battery by an orange one. The test button checks the whole circuit, and with a flat battery the detector stops working. The instruments comply with IEC 61243-1 / UNE-EN 61243-1 and work from −25 to +55 °C. The optical VTO-U, VTO-P and the compact PEKE for 5–36 kV with a built-in telescopic stick per RD 614/2001 need no batteries, because self-test is done by a piezo generator. The VTC-OAD for direct current also shows induced AC voltage from neighbouring systems up to 25 kV, has a flexible 6 m earthing lead in a silicone sheath and switches off after 2 min without detection.

How to choose

The detector range must match the nominal voltage of the installation. The VTM is made from 3–10 to 22–66 kV, the VTE for 5–35 or 5–66 kV, and for 25 kV high-speed railways there is the VTE-25-U. In tunnels and in poor lighting the POWER LIGHT with a torch is handier (from 1–3.3 to 22–79 kV, 360° indication), and there are also the POWER LIGHT DUAL and POWER-10/20. Low voltage is checked by the SPECTRA at 200 V – 5 kV or 50 V – 1 kV, and the POWER SALVACANE (24 V – 5 kV) on wheels looks for voltage on manhole covers and in paved areas.

FAQ

What battery do the VTE and VTM detectors use?

A 9 V battery of type 6LR61. After 2 min without voltage the unit goes to sleep and consumes less than 1 µA, and it switches on by itself as soon as it detects voltage.

How does the optical VTO detector differ from the electronic VTE?

The VTO works without a battery, and self-test in it is done by a piezo generator. The VTE has a microcontroller and an audible signal but needs a battery.

Which detector should be used for a 3 kV DC network?

The VTC-OA or VTC-OAD, both rated for DC 500–5000 V. The VTC-OAD also warns of induced AC voltage.

Where are these voltage detectors used?

In switchgear and packaged transformer substations, on 6–35 kV overhead lines, at traction substations and in railway catenary networks.
