SETTING CHECK (DIFFERENTIAL & BIAS FEATURE CHECK):Ensure all the settings are applied.

BIAS CHARACTERISTIC TEST:

Lower Slope Check - Set the relay in Test Loop back mode

- Set relay as 1st = 0.2A, k1=30% 1s2 = 2A- Set phase & E/F CT correction Factor = 1.00

Upper Slope Check :

- Set the relay in loop back mode- Set relay as 1s1 = 0.2A, k1=30%, 1s2 = 2A, k2=as in table below
