6.4.2 Test circuit

For testing the voltage functions of the MRG3-relay a three phase voltage source with adjustable

voltage and frequency is required. Figure 6.1 shows an example of a three-phase test circuit ener-

gising the MRG3 relay during test. The three phase voltages are connected to the relay in Y-

connection.
