選擇 RCD
選擇斷路器在跳閘的時(shí)候有一個(gè)時(shí)間延遲。對(duì)于選擇的,允許在測(cè)試故障電壓和測(cè)試電流應(yīng)用的時(shí)候,跳閘測(cè)試時(shí)間就會(huì)有點(diǎn)延遲甚至可能有 30 分鐘的延時(shí)。
接觸電壓制約有 25V 或 50V 可供選擇。
儀器外殼包裹著堅(jiān)硬的橡膠,確保儀器和測(cè)試操作問(wèn)員的安全。
使用簡(jiǎn)單,沒(méi)有隱藏的功能,這就意味者對(duì)于怎樣使用測(cè)試儀器一目了然。
在儀器上對(duì)于量程選擇有明顯的顏色標(biāo)識(shí),這樣就減少了量程選擇誤差,并且減少測(cè)試時(shí)間。
帶有使用手冊(cè),其功能應(yīng)用都有詳細(xì)的介紹。
它能掛在脖子上,也能拿在手上,因?yàn)閮x器不僅輕便,而且平衡性很好。
可以在 1/2 I, 1xI 和 5xI的狀況下測(cè)試直流靈敏RCD。
斜坡測(cè)試( RCDT320/330)
測(cè)量 RCD的跳閘電流。電流電平慢慢從1/2 I 增加到 1I (+10%)。當(dāng)RCD跳閘的時(shí)候,跳閘電流就會(huì)顯示在顯示屏上。
能非常有效的診斷有損害的 RCD跳閘。
自動(dòng)測(cè)試( RCDT320/330)
當(dāng)在測(cè)試 RCD 的時(shí)候,但是操作者要去別的地方,這時(shí)操作者只需要給儀表設(shè)置一些參數(shù)就可以走開(kāi),儀器就會(huì)自動(dòng)進(jìn)行 1/2 I, I 和 5I 測(cè)試,測(cè)試可以在0o 和 180o。RCD在每次跳閘后自動(dòng)重啟,好讓使用者能進(jìn)行下次自動(dòng)測(cè)試。所有的測(cè)試結(jié)果都會(huì)顯示和存儲(chǔ)下來(lái),節(jié)約你的時(shí)間和精力。
RCDT330還帶有能把測(cè)試結(jié)果保存到內(nèi)存中的功能。超過(guò)1000組測(cè)試結(jié)果可以存儲(chǔ)起來(lái)。測(cè)試結(jié)果儲(chǔ)存在不可邊內(nèi)存中,在關(guān)閉儀器或者電池沒(méi)電后,測(cè)試結(jié)果都不會(huì)丟掉。
在儀器上有一個(gè)內(nèi)存顯示條,顯示儀器內(nèi)存已經(jīng)使用了多少。
測(cè)試結(jié)果能通過(guò) CSV軟件下載下來(lái),下載的結(jié)果以Microsoft Excel 表格形式顯示。

Megger RCDT300
RCD testers for electricians
• Tests standard, DC and selective RCDs
• Ramp testing
• Auto (Remote) testing
• 3 Phase safe
• Enables testing on 110 V centre tapped supplies.
• Tough rubber armoured case with built-in cover
• Weatherproof to IP54
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.
