There follows a list of tests which can be used to check that the unit is fully operational. For a more limited
test for the reception of units we recommend carrying out only the tests listed in sections: 6.2, 6.5, 6.8, 6.9,
6.10, 6.11 and 6.12.
6.1. CONNECTIONS AND NECESSARY EQUIPMENT
Necessary equipment:
•
3 voltage sources and 3 current sources, mutually dephasable
•
One DC voltage power supply
•
One chronometer
•
One multimeter
•
One auxiliary relay to simulate a Breaker
•
Optionally, it is advisable to have a PC available, with the GE_LOCAL software installed and the data
base file related to the appropriate SMOR relay.
Connect the relay as indicated in the external connections diagram, Figure 7.
Connect 3 current sources.
The first is connected to phase A on terminals A1 and A2. The second source is connected to phase B
(terminals B1-B2) and the third one to phase C (terminals A3-A4), connecting the return of the three phases
to the ground current input (terminals B3-B4).
3 voltage sources also need to be connected to phases A (terminals A5 and A6), B (terminals B5 and B6)
and C (terminals A7 and A8).
For safety reasons, the external protection earth terminal should be securely grounded.
Supply the unit through terminals A10 and B10 at the nominal DC voltage.
An auxiliary relay is used to simulate the operation of a Breaker. The opening coil will be connected to relay
trip output (terminals A11 and B11). The Closing coil of the auxiliary relay will be connected to the reclose
output (terminals C1 and D1). In order for the relay to be able to detect the status of the Breaker, a 52/b
contact of the auxiliary relay (a contact which is open when the relay is closed) must be wired to the 52/b
input on the SMOR relay (terminals C9 and D10).
Jumpers and switches are used to simulate the Closing of the external contacts.
