Configuration

Example:

System Configuration

CT = 1400:5
PT = 2:1

Desired value to monitor

watthours

System parameters

Assume

the IQ 320 is monitoring a constant system power of

16,800 Watts.

Step 1

: Calculate the CT and PT ratios

CT ratio = 1400/5 = 280
PT ratio = 2/1=2

Step 2

: Calculate the power at the secondary of the CTs and PTs

power at secondaries =

16,800 Watts / (CT ratio x PT ratio)

power at secondaries =

16,800 Watts / (280 x 2)

power at secondaries =

16,800 Watts / 560

power at secondaries =

30 Watts (or 30 watthours in 1
hour)

Step 3

: Specify the energy per pulse as desired

Specify secondary energy per pulse = 1 watthour per pulse;
then, each pulse represents system energy of:

(1400/5) x (2/1) x 1; or 560 watthours per pulse

Specify secondary energy per pulse = 7 watthours per pulse;
then, each pulse represents system energy of:

(1400/5) x (2/1) x 7; or 3,920 watthours per pulse
