5. There are two methods to test sensitivity

5/1 by applying value in ph R =0.2 A if no trip stop the test and increase the value to 0.3 A

to get the min pickup value

5/2 by applying value in ph R =0.2 A and make auto test by adjust the increasing value and take stop contact from the diff. relay to stop test at the pickup value So adjust step like as fellow:

Triple = CMC156-EPI

size = 0.01 A

Quantity = I1

time = 0.5 S

And select auto step and select stop contact then press test

6. For test harmonic in the main screen press testing tools then press harmonic

7. This screen will appearput Ia = 5 A time = 1 S select Ia from here and harmonic value = 22 % then file - export

Then inject ph R = 2.5 A angle 0 and connect it to ph R HV side,

Inject ph S = 1.443 A angle 180, ph T= 1.443 A angle 0 and connect it to ph R ,ph T LV side consequently

Then start test and read the measurements from TDP software and take Id , It
