Issue
User would like to know how the TLC is calculated in Single phase testing mode of ION 7550/7650 or ION8600/8650
Product line
ION 7550/7650 ION8600/ION8650
Resolution
Single-phase test option lets you use a single-phase source and view three phase. When the single phase testing is enabled, the meter will calculate the V2 Average, V4 Average and I2 average from the single phase source according to the following calculations:
For a Wye system:
For a Delta system:
The above parameters are then used to calculate the losses according to the following :
You can also connect a single‐phase source voltage inputs in parallel and the current in series to simulate a three‐phase source without toggling to the single phase mode.
