Users Manual

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.

Note

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).
