Description
Megger RCDT300 Series Residual Current Device Tester
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 (Comma Separated Variable) spreadsheets, and can be imported into Microsoft Excel®. 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 for NICEIC, ECA BS and other standard formats.
Key Features:
- n Tests standard, DC, selective, and programmable RCDs
- Ramp testing n Auto (Remote) testing
- 3 Phase safe n Enables testing on 110 V centre tapped supplies.
- Tough rubber armoured case with built-in cover
- Weatherproof to IP54
- USB interface for downloading test result
Description:
Standard test ranges
- The RCDT300 series can perform 1/2I, 1xI and 5xI tests on RCDs rated at 30 mA, 100 mA, 300 mA and 500 mA on general and selective (time delayed) RCDs. The RCDT320/ 330 can also test RCDs rated at 10 mA and 1000 mA. All units offer DC testing of RCD’s.
Test times for normal and Selective RCDs are:
Normal Selective
1/2I 2s 2s
I 300ms 2s
5I 40ms 150ms
- 5I tests are available on RCDs rated up to 100 mA.
Polarity
- All RCD's can be tested at 0° or 180°
- Selective breakers have a time delay in tripping. When selected, trip test times are extended and a 30s delay is allowed between the measurement of the fault voltage and the application of the test current.
- Touch Voltage is measured at the start of the RCD test. If enabled it is displayed on the analogue arc on completion of testing.
- Designed to take the bashing that testers receive on site, the Megger RCDT testers are rubber armoured.
- The rigid display cover folds right out of the way during testing and locks down to protect the display when it is finished.
- No buried functions mean it is obvious how to use the Megger RCDT.
- Colour coded ranges help test range selection, reducing test times and fault location.
- A user guide in the lid provides all the basic information. Hands free use
- It hangs comfortably around the neck for hands-free use because the instrument is carefully balanced.
- DC sensitive RCDs can be tested at 1/2I, 1xI and 5xI.
- (RCDT320/330) n To measure the trip current of an RCD. Current level is slowly increased from 1/2I to 1I (+10%). When the RCD trips the trip current is displayed and held on the screen.
- Very useful diagnosing nuisance tripping of RCDs.
