Waveform/Fault Recorder:

To protect critical billing information, the meter records and logs the following with a time stamp:

Simultaneous Voltage and Current Waveform Recorder

EIG meters provide the pre-fault and post-fault event recording / Waveform records are programmable to the desired sampling rate.

The meter’s advanced DSP design allows Power Quality triggers to be based on a 1 cycle updated RMS. The meter stores waveform data in a first-in/first-out circular buffer to insure data is always recording. The unit records up to 512 or 1024 or up to 50 MHz samples per cycle for a voltage sag or swell or a current fault event depending up on various models.

Waveforms at a sampling rate of up to 1024 samples/cycle on multiple power quality events, including surges, sags, and transients. 16-bit A/D conversion provides precise waveform resolution. Both voltage and current recording offer pre- and post-event analysis. Fault recording offers eight times full-scale capture capability. Waveform recording for wideband frequencies is also supported. You can program both hardware and software triggers to record a waveform. View waveforms through Communicator PQA ® software, the meter’s web browser, or the EnergyPQA.com® cloud-based energy management system. You can also download the waveforms to third party software for analysis. Analyze the waveforms to determine the source of power quality anomalies and then take steps to remedy the situation.

Power Quality Measurement:

Power quality Measurement becomes basic necessity with many sectors are coming with various power electronics, solar power, and wind power , furnaces, SMS etc. Monitoring Power quality continuously is the only way to identify as well as understanding source of problems for rectification.

some inputs which can be further investigated with international standards.
