Application Example

Using Laureate Meters, Counters or Transmitters to Synchronize Motor Generators

Synchronization of two motor generators requires that
the two frequencies be identical, that the lines be in
phase, and that the line voltages be close to each other.
In this illustration, a single Laureate dual channel
counter (or frequency transmitter) measures both
frequencies to six-figure accuracy in a few line cycles.

Another Laureate dual channel counter (or phase
transmitter) measures phase angle to 0.1° resolution.
Two Laureate AC RMS Voltmeters, which offer ranges
of 200.00 V and 600.0 V, are used to display the two
RMS voltage to 0.1% accuracy.
