4–354 845 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
TESTING CHAPTER 4: SETPOINTS
To configure the pickup setpoint for a total arcing current of 5000kA
2
/cycle, the per-unit
pickup value can be calculated as follows:
Pickup = 5000kA
2
*cycle/2000 kA
2
*cycle = 2.500 pu

•Test LEDs
•Contact Inputs
• Output Relays
The 8 Series can simulate current and voltage inputs when the Simulation feature is
enabled. Other test operations are also possible such as the LED lamp test of each color,
contact input states and testing of output relays.
