Step 3)
Jumper between one pin of the " " onne tor and one pin of the “ ” onne tor and onne t an
ammeter between the remaining two pins, as shown.
Step 4)
Input the desired primary current at positions 5-5 on the terminal block and note the current flowing
in the circuit. You now have the exact internal CT ratio of input to output current at secondary load.
Disconnect the power before disconnecting the ammeter and jumper
–
the secondary leads must
always be connected in-circuit or shorted when the CT is powered.
Step 5)
Using the measured secondary current, re-calculate the desired R5-5 value which will provide the
exact heater current necessary for the desired winding simulation. Using an ohm
meter at the “ ”
pins, adjust the matching resistance to meet this R5-5 value.
Step 6)
Re-connect the white separable connector. After the matching resistance has been set and the
white connector is re-mated, the winding simulation input current is wired to the terminal block at
the 5-5 positions as shown in the
TD50(5AMP) Wiring Example
below.
