TEST PANEL FOR ROUTINE TESTING OF RCCB

Test RCCB as per Annexure D of IS 12640 (Part 2) 2008 and IEC 61009-1:1996 Edition 2.2, 2006.

Pneumatically controlled fixtures for loading and unloading with user safety
PC based test operation, control and data keeping
Indication lamps and relevant metering: To display the applied High Voltage
The test section is housed in transparent cover for user safety: Loading and unloading of RCCBs is automated without opening the front cover
Isolated section for HV circuit for safety of maintenance personnel
Ideal for routine testing for RCCBs
Cabinet: MS fabricated steel with extruded aluminum

  • Tripping Test as per specifications for I_an= 30 mA, 100 mA, 300 mA

  • Di-electric strength test for different pole combinations as specified by user: 0-5 kV variable

  • Performance test as per customer specifications.

  • Can test two pole / four pole RCBOs

  • Fully automated panel with two test stations

  • PLC based with Siemens make PLC and touch screen monitor

The Test Panel is designed to carry out Routine Test of RCCB/AOB + MCB as per Annexure D of IS 12640 (Part 2) 2008 and IEC 61009-1:1996 Edition 2.2, 2006.

The Test Panel will be PLC based with Touch Screen for monitoring and controlling the sequence and will include a PC for storing the data. The interface module is user friendly and also contains a diagnostic mode for checking the fixture and pneumatic operations thus enabling ease of maintenance and operator training. The PLC is interfaced with a PC with installed NI LabVIEW software for data logging and data export.

The specialty of the test system is its speed: Tripping current test (for both trip and no trip), Di-electric withstand test (various live and neutral pole combinations) and push button test are covered in two and a half minutes and 2 RCCB samples are tested simultaneously thus bringing the testing speed to about 50 RCCBs per hour for 4 pole RCCBs. The speed of testing is better for two pole RCCBs.

The test jig will be specially designed to suit an RCCB of your make. The test jig is fully automatic and controlled by the PLC. All the user needs to do is push the RCCB tray gently inside the system. Safety features include a glass acrylic cover and a glass flap to prevent accidental / intentional intrusion of hand in the testing section of the jig.

The will be designed for 2 Stations controlled independently by a single PLC.

Test Sequence:

  1. Tripping Test as per customer specifications for Ian – 30mA, 100mA, 300mA (User may specify the exact value). (Test D.1 in Annexure D)

  2. Electrical Strength Test (High Voltage) of Voltage 2.5 kV as per different combination of live and neutral poles for 4 pole or 2 pole products

  1. Test Upstream / Downstream (Conventional Di-electric testing with shorting of all live poles and all neutral poles and HV test between live pole and neutral pole) (test b in Annexure D.2)

  2. Test between each pair of terminal on either side: Live and Neutral (test a and c in Annexure D.2)

  1. Performance of Test Device (Push Button Test) (Test D.3 in Annexure D)

Specialized Fixture: To carry out the above test in a glass enclosed cabinet, specialized pneumatic-based fixture will be designed and built as per user samples of RCCBs. This fixture will be able to accommodate two RCCBs in 2 different test stations. These will be operated automatically (for the above test sequence) with the help of PLC and the online test status will be displayed on PC.

The system will comprise of:

    1. PLC System with Siemens manufactured PLC and Touch Screen Monitor.

    2. Programmable Current Sources – 2 Nos.

    3. Separate High Voltage Source Module for carrying out Di electric withstand test with user configurable test parameters

    4. Pneumatic Fixtures – 2 Nos. (Glass Enclosed for User Protection)

    5. Computer system with SCADA Software.

    6. The entire system will be housed in elegant Aluminum Extruded Sections.
