Voltage fluctuation and fault waveform recording

Capture all waveforms of voltage and current channels and analyze the interference source when the power grid is abnormal. When the harmonic distortion rate, voltage RMS and voltage unbalance exceed their limits, the voltage waveform and fault waveform recording are started to provide accurate data for the power quality management of power grid.

Harmonics analysis

Harmonics up to 63th order, interharmonics up to 50th and higher frequency harmonics of 2k~9kHz can be analyzed, which meets the harmonics testing requirements of public power grid specified in the GB/T 14549 and IEC 61000-4-7 standards.

Event alarm monitoring

The E2000 can detect power transient and steady-state events. The events are listed in the descending order, and the most recent event is placed in the top row. Users can position the cursor on the event list to view events by page. Furthermore, the event list can also be queried by date, therefore users can quickly and correctly locate the power quality problem by viewing past events.

Time Calibration

There are multiple time calibration methods, including SNTP, B code and PPS.

Multi-standard Protocol

Multiple communication protocols are supported, including Modbus (485/TCP) and IEC103.

Support for standardized data formats

It supports the PQDIF common standard data exchange format specified in IEEE 1159 and the IEEE Comtrade transient data exchange format for power systems.
