Thisis a GO-NOGOTestwhich allowsto confirmthe holdingcurrent(I

circuit.
Thistest canbe performedif thereferencetestcircuit can’tbe implemented.
TESTPROCEDURE:
1) Adjustthe currentlevel at the I
H
valueby short circuiting the AK of the D.U.T.
2) Firethe D.U.T witha surgeCurrent: Ipp = 10A, 10/1000

3) TheD.U.T will comeback to theOFF-Statewithina durationof 50ms max.
TESTPROCEDURE :

- For Bidirectionaldevices= SwitchK is closed
- For Unidirectionaldevices= SwitchK is open.
