Arbiter 933A Portable Power Sentinel Power Quality Meter
The Arbiter 933A Portable Power Sentinel is a cutting-edge power quality meter engineered for precision and affordability. Utilizing proprietary EnergyDSA Digital Signal Analysis algorithms, this device empowers users to measure and record critical power quality parameters, including harmonics, flicker (per IEC 61 000-4-1 5, PST and Instantaneous), K-factor, and interruptions. With its impressive accuracy and portability, the Portable Power Sentinel stands as an essential tool for any power quality engineer.
Key Features
- Lightweight design: Weighing less than 5.8 kg (12.8 lbs), making it easy to transport.
- Multi-functional capabilities: Acts as a power quality monitor, data and event logger, system monitor, and revenue meter.
- Advanced measurement capabilities: Records harmonics, flicker, K-factor, and interruptions, as well as system time, phase, frequency, and phasors.
- High DSP memory: Stores waveform data continuously at approximately 170 samples per cycle, with a fixed pre-fault window of 0.5 seconds, allowing for up to 1,000 seconds (17 minutes) of data storage.
- Optional features: Includes remote GPS receiver synchronization for 1 µs timing accuracy, optically isolated event inputs, flexible CT inputs, direct current inputs, and programmable KYZ output contacts.
