Primary Injection Test on CT’s Ratio & Polarity
1. Ensure that the switchgear has been de-energized.
2. Note down the particulars of the switchgear and CT’s.
3. Do not remove any wires, use the provided test plugs if applicable or use
clamp meters.
4. Measure the CT’s secondary phases and spill current using a clamp meter.
5. Select all meters to ampere range.
6. Inject a current of 10 to 20A onto the brown and black phases. Check the spill current,
it should be as low as milli-ampere. If the spill current is high, check for CT’s terminal
tightness or any mistake on the wiring.
7. Reduce to zero and off the supply, change the spill current meter (A4) to milliampere
range.
8. Inject a current of 50% and 100% of the CT primary current on brown (L1) and black
(L2) phases. Record the reading.
9. Reduce to zero and off the supply.
10. Repeat item 6 to 8 for black (L2) and grey (L3) phases.
11. Repeat item 6 to 8 for brown (L1) and grey (L3) phases.
12. Select all meters to ampere range.
13. Inject a current of 10 to 20A onto black phases (L2) to earth. Check the spill current
(A4). It should be the same current as the phase current (A2).
14. Inject a current of 50% and 100% of the CT primary current on black (L2) phase to
earth. Record the reading.

Secondary Injection Test 1. Ensure that the switchgear is de-energized.
2. Note down the relay particulars on test form.
3. Check or record the setting of the relay.
4. Increase the current gradually until the relay pick up. Record the reading.
5. Set a current of two times of the plug setting and off the injection set.
6. Press the start button of the injection set and record the tripping time as shown on the
test equipment.
7. Repeat item 5 to 6 for three and five times of the plug setting.
8. Repeat item 5 to 7 for black (L2) and grey (L3) element.
9. Repeat item 4 to 7 for earth element.

Secondary Injection for Pilot Wire Relay Operation Check
1. Ensure that the switchgear is de-energized and PTW is issued.
2. Remove the relay from the casing and check the relay connection. It is either
Solkor R or Solkor Rf mode. Typically it is used at Solkor R mode. Change the
connection accordingly to your application.
3. Connect the circuit on Brown (L1) and neutral phase as shown on the diagram.
4. Increase the current gradually until relay pick up. Record reading A1, A2, A3 and A4
on the test form
5. Increase the current furthermore until the dummy relay pick up.
6. Record reading A1 on the test form.
7. Repeat step 3 to 5 for Black-E, grey-E, Brown-Black, Black-Grey and Grey-brown.
