Made 2 Measure: is there a tester that can identify live cables and cable breaks? | Megger
The technical team at Megger answer another common contractor-related product query.
I’m looking for a simple tester to help me identify live cables and find cable breaks. What can you suggest?
Non-contact voltage indicators are very useful devices that, in most applications, will do exactly what you want. Some of them also offer valuable extra features. The new Megger VF5 AC non-contact voltage detector, for example, has both low voltage (12 – 1,000 V) and medium voltage (100 – 1,000 V) detection ranges. In addition, it has a bright white LED torch built in and an additional LED torch at the detector end.
When the VF5 detects an AC voltage, the tip LED changes colour, an audible sounder operates and the whole detector vibrates, which is very useful if you’re working in a noisy environment. As well as detecting AC voltage – at, for example, socket outlets, switches, circuit breakers, fuses and luminaires – the VF5 can easily identify cable breaks. When working on any live system safety is key, and the Megger VF5 has a market-leading CAT IV 1000 V rating. It also has an IP67 ingress protection rating.
Another alternative is the Megger VF6 EX. This has all the same features as the VF5 but is ATEX approved so you can use it in hazardous areas such as garage forecourts, petrochemical plants and gas platforms.
