选择 RCD
选择断路器在跳闸的时候有一个时间延迟。对于选择的,允许在测试故障电压和测试电流应用的时候,跳闸测试时间就会有点延迟甚至可能有 30 分钟的延时。
接触电压制约有 25V 或 50V 可供选择。
仪器外壳包裹着坚硬的橡胶,确保仪器和测试操作问员的安全。
使用简单,没有隐藏的功能,这就意味者对于怎样使用测试仪器一目了然。
在仪器上对于量程选择有明显的颜色标识,这样就减少了量程选择误差,并且减少测试时间。
带有使用手册,其功能应用都有详细的介绍。
它能挂在脖子上,也能拿在手上,因为仪器不仅轻便,而且平衡性很好。
可以在 1/2 I, 1xI 和 5xI的状况下测试直流灵敏RCD。
斜坡测试( RCDT320/330)
测量 RCD的跳闸电流。电流电平慢慢从1/2 I 增加到 1I (+10%)。当RCD跳闸的时候,跳闸电流就会显示在显示屏上。
能非常有效的诊断有损害的 RCD跳闸。
自动测试( RCDT320/330)
当在测试 RCD 的时候,但是操作者要去别的地方,这时操作者只需要给仪表设置一些参数就可以走开,仪器就会自动进行 1/2 I, I 和 5I 测试,测试可以在0o 和 180o。RCD在每次跳闸后自动重启,好让使用者能进行下次自动测试。所有的测试结果都会显示和存储下来,节约你的时间和精力。
RCDT330还带有能把测试结果保存到内存中的功能。超过1000组测试结果可以存储起来。测试结果储存在不可边内存中,在关闭仪器或者电池没电后,测试结果都不会丢掉。
在仪器上有一个内存显示条,显示仪器内存已经使用了多少。
测试结果能通过 CSV软件下载下来,下载的结果以Microsoft Excel 表格形式显示。

MEGGER BOOSTS SAFETY IN RCD TESTING
Even if they are inadvertently connected to a live three-phase supply, RCD testers in Megger's new 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, ensuring that all users can choose a model which exactly meets their needs, RCDT300 RCD testers feature a compact ergonomic design, making them easy to handle and use, and a tough impact-resistant body 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 ingress protection rating.
The low-cost entry-level RCDT310 model is suitable for use on supplies between 100V and 280V, and offers 0.5I, I and 5I tests, with provision for tests starting at 0ْ/180ْ 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.
The mid-range RCDT320 covers a wider supply voltage range of 50V to 290V, allowing use with centre-tapped 110V supplies. It incorporates ramp testing 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.
The operating current range of the RCDT320 is extended to cover 10mA to 1,000mA devices, and the ability to measure AC supply voltage and frequency is added. The large liquid crystal display for test results is backlit in this model, making it easier to use in locations with low ambient light levels.
The RCDT330 additionally offers the facility to save test results to internal memory. Over 1000 result can be saved on site, and downloaded to a computer when convenient.
Data is stored in non-volatile memory, being retained when the instrument is switched off or batteries are exhausted.
A Job reference number can be selected for a range of results, allowing separate locations to be tested with the same tester and easily separated when downloaded.
A memory bar graph acts as a ‘Fuel Gauge’ showing how much memory has been used. Test results are downloaded to CSV (Coma Separated Variable) spreadsheets.
If certificates or reports are required, the results can be downloaded directly into Megger Powersuite Professional with a range of features for creating professionally finished documentation.
All models in the range comply fully with the requirements of IEC61010-1 for Category III 300V applications, and are supplied complete with appropriate test leads and a calibration certificate.
