Command

Purpose

SG-CT=1

Sets CT ratio at 1.

SG-TRIGGER=50TQT+50TQPU,
150TQT+150TQPU,0

Enable 50TQT and 150TQT to log and trigger fault recording.

EXIT;Y

Exit and save settings.

Step 3: Using Table 13-18, transmit the first column of setting commands for your sensing input type

(substitute 0.1 for 1 amp CT).

Table 13-18. 50TQ/150TQ Time Delay Settings

Pickup and Time Delay Settings

Purpose

2 Second TD

5 Second TD

10 Second TD

S0-50TQ=0.5,2S

S0-50TQ=0.5,5S

S0-50TQ=0.5,10S

Sets 50TQ TD.

For a single-phase input test, I

2

= Ia ÷ 3. Therefore, the relay should pick up at a value of three times the

setting value when applying only a single-phase input. For example, to determine the pickup current value
required for a 1-amp relay with a pickup setting of 0.1, it would require 0.1 times 3 or 0.3 amperes of input
current.

Step 4: Step the applied A-phase current to 110% of pickup. Measure the time delay and verify the

accuracy of the 50TQ time delay setting, OUT1, and 150TQ, OUT2. Timing accuracy is

±5

percent or

±3 cycles of the time delay setting.

Step 5: Repeat Step 2 and 3 for the middle and higher time delay settings in Table 13-18.

Step 6: (Optional.) Repeat Steps 3 through 5 for phase B (Terminals D3 and D4) and phase C

(Terminals D5 and D6).

Step 7: (Optional.) Repeat Steps 1 through 6 for Setting Group 1.

50TN/150TN (Independent Ground Input IG) Pickup and Dropout Verification

Purpose: To verify the operation of the 50TN and 150TN elements for IG input.

Reference Commands: SL-50TN/150TN

Step 1: Connect a current source to Terminals D7 and D8 (IG).

Step 2: Prepare the 50TN and 150TN elements for testing by transmitting the commands in Table 13-19

to the relay. Reset targets.
