3.2.1.2 Potential Transformer secondary Value
The value must be set to the nominal full scale secondary voltage which will be obtained from the
the Transformer when the potential transformer(PT)primary is supplied with the voltage defined
in 3.2.1.1 potential transformer primary voltage. The ratio of full scale primary to full scale
secondary is defined as the transformer ratio.
Here again 0 to 9 digit input keypad is provided to set value of PT
Secondary, & user can confirm this value with a simple touch on
This screen can be accessed only from system parameters list menu.
