Model 1133A Power Sentinel
The Model 1133A brings laboratory performance to the substation, delivering unprecedented revenue accuracy of 0.025% under most conditions
Revenue Metering
Arbiter Systems®, Inc. combines state-of-the-art measurement techniques, proprietary EnergyDSATM technology, and the accurate, cost-effective time synchronization of our precision GPS clock products in the Model 1133A Power Sentinel™. The Model 1133A brings laboratory performance to the substation, delivering unprecedented revenue accuracy of 0.025% under most conditions.

Power Quality Monitoring
The Model 1133A's features only begin with its outstanding accuracy in energy measurement. Power Quality signals available for recording in the standard 8 MB of non-volatile memory are harmonics and K-factor, flicker, interruptions, out-of-limit events with time of occurrence. Also, an alarm contact may be activated, or a dial-up modem call initiated.

System Control and Monitoring
The Model 1133A measures system (absolute) phase angle, frequency deviation, and time deviation. Also, phasor measurement data, at a rate of 20/second, is standard.

Synchronization
A built-in Global Positioning System (GPS) satellite receiver synchronizes your Model 1133A within 1 µs of Coordinated Universal Time (UTC). Synchronization allows revenue data to be accumulated in time slots as short as one minute. Other substation equipment, such as digital fault recorders, may be synchronized with the IRIG-B output.

Technology
At the heart of the Model 1133A's revolutionary performance lies Arbiter Systems' many years of experience in accurate measurements and state-of-the-art timing equipment. Built-in, real-time autocalibration eliminates many sources of error. By passing the calibration signal through the same measurement circuits as the input signals many errors are completely removed.
