State of the Art

COMPUTER-BASED POWER QUALITY MONITOR

The PQM-200 is a computer-based Power Quality Monitor with up to 48 input channels. It combine functionalities of a Power Quality Monitor, Disturbance Recorder, Power Fault Recorder, Transient Recorder, Phasor Measurement Unit (PMU) and high precision energy meter. The input modules are fully-isolated (isolation voltage 6kV) and provide a synchronized sampling rate of 144 kS/s per channel and 24 bit resolution. An Automatic Anti-Aliasing filter together with extremely low-noise ensures signal quality and signal processing.

Hybrid Data Storage

Even if connection is lost all data are stored locally and will be transferred after reconnection.

Data on demand

All data can be transferred continuously or just triggered on demand.

Remote Configuration

The instrument can be configured remotely or locally. Either option also can be disabled.

Remote Location

All data can be transferred via Ethernet and via a GSM connection.
