1. Connect the voltage test leads to the outputs of the voltage
transformers (VTs).
2. In PQ Log, select the measuring range with P-N logging and
matching nominal voltage.
3. Enter the correct converter/transformer ratio for current and voltage.
Current clamp sets are available for 1 A current transformers.
Logging with Two Voltage Converters and Two Current
Transformers
In 3-phase 3-wire systems with two voltage converters (VTs) and two current
transformers (CTs) in an Aron or Blondel measuring circuit, the Logger can
measure only phase-phase (P-P, Delta).
