Secondary injection tests can pinpoint defects in a trip unit or other protective schemes ensuring that the system is functioning normally.
A full function test kit, the Square D by Schneider S33595 Secondary Injection Test Set is designed to perform tests on Micrologic, NT and STR Trip units.
The Square D by Schneider S33595 consists of a signal-injection box which can be used alone or with a supporting personal computer (PC). The optional test kit software is compatible with Windows® 95, 98 and Windows NT® operating systems.
Without a supporting PC, the Square D S33595 may be used to check:
- The mechanical operation of the circuit breaker
- The electrical continuity of the connection between the tripping coil and the trip unit
- Trip unit operation:
— Display of settings
— Operating tests on the electronic component
— Automatic and manual tests on protection functions (trip curve verification)
— Tests on the Zone-Selective Interlocking (ZSI) function
— Inhibition of the ground-fault protection for equipment
— Inhibition of the thermal imaging
