Bridging the gap between Precision Timing and Power Quality Measurement, Model 1133A Power Sentinel™ delivers practically unlimited functionality to the electric power professional.

Compliant with IEEE C37.118, Model 1133A is a rack mountable Phasor Measurement Unit (PMU) compatible device featuring the highest accuracy possible.

Functionally, the unit provides exceptional support for synchronized timing applications enabling Model 1133A to take a leadership role in synchrophasor measurement and analysis. Measure system phase angle, monitor power quality, derive frequency and time deviations and tackle revenue metering challenges from a single unit.

The advanced technology, featuring Arbiter's proprietary EnergyDSA™ Digital Signal Analysis technology makes all of this - and more - possible.
