MEGGER BOOSTS SAFETY IN RCD TESTING
Even if they are inadvertently connected to a live three-phase supply, RCD testers in Megger’s RCDT300 range remain undamaged, and present no safety hazard to the user. Introduced after extensive customer research into the requirements of electrical contractors, these innovative instruments combine rugged construction with straightforward operation, and they are offered at very competitive prices.
Available in three models RCDT300 RCD testers feature a compact design, making them easy to use, and tough with a rubber overmoulding for additional protection, plus a built-in display cover. All models in the range are water and dust resistant, with an IP54 rating.
RCDT310 model is suitable for use on supplies between 100 V and 280 V, and offers 0.5I, I and 5I tests, with provision for tests starting at 0° or 180° of the supply waveform, as well as for DC tests. It also has facilities for testing standard and selective RCDs, and covers current ranges from 30mA to 500mA. When connected to a live supply, it defaults to voltmeter mode.
RCDT320 covers a wider supply voltage range of 50 V to 280 V, allowing use with centre-tapped 110 V supplies. It incorporates ramp testing, for RCD tripping current measurement, and the unique Megger auto sequence test feature, which saves time by allowing the tester to conduct all the RCD tests, and to store the results while the operator stands by the RCD, resetting it as appropriate.
