TRISAN S8 Appliance Categories and test sequences
Residual current devices (RCD)…..Treatment
When testing RCD’s a 10mA or 30 mA. Sinusoidal waveform is instantaneously applied at 0° where the time is
measured to trip the tested RCD. The test is repeated for 180°.
For 10mA RCD. The trip time should be < 40ms. For a PASS
For 30mA RCD The trip time should be < 300ms. For a PASS
When testing portable RCD’s the TRISAN S8 inserts isolation circuitry to ensure any fixed RCD (in the mains
supply) is not tripped.
Portable RCD’s are treated as an extension leaded appliance and therefore a pre-test lead test is performed on
the Portable RCD, measuring earth resistance, polarity and leakage current before proceeding to measure trip
time.
11 Portable RCD 10mA.
Tests include:
1. Earth resistance < 1ohm. ……………..PASS
2. Polarity…...A - N correct orientation….PASS
3. Leakage current < 1mA………………..PASS
( NOTE: for RCD’s with test button 5mA is the maximum allowed value)
A prompt will appear for a response from the operator if leakage current exceeds 1mA
4. Trip time < 40ms………………………PASS
Set-up:
Select 10mA Portable RCD from OTHER APPLIANCE menu.
Connect P RCD appliance between leads socket and RUN/LEAKAGE socket.
Press START.
Prompt appears on screen Use “Run test socket”
Press START.
Prompt appears Arm RCD then hit START.
The S8 tests continuity and leakage current after this operation.
Prompt appears if electrical tests are successful
Time RCD
START
Press START button.
PASS or FAIL trip time and screen displays trip time.
Repeats for 180° trip time test.
12 Portable RCD 30mA.
Operation as outlined above
