Application Field

Suitable for gateway metering points such as power generation enterprises' grid connections, cross-regional tie lines, provincial grid tie lines, and provincial grid intake points, as well as scenarios with frequent load fluctuations like electrified railways and large industrial users.

Product Features

No signal distortion under non-linear loads.

Multi-ferroelectric memory backup technology ensures the reliability of core parameters and data.

Long-term stable and reliable operation with a long service life.

Negligible impact of environmental temperature and load changes on metering accuracy.

Some indicators outperform similar foreign products.

Negligible calculation errors under non-linear and non-periodic loads.

Main Functions

Time-of-use metering for bidirectional active energy, four-quadrant reactive energy, and two combinations of reactive energy.

Time-of-use metering for maximum demand (active and reactive) and its occurrence time.

Supports up to 8 tariff rates, dual main/auxiliary time periods, and records historical data for up to 12 months with a maximum of 3 settlements per month.

Configurable for 6 types of load curve data recording.

Features precise periodic energy freeze functionality to meet high-reliability data requirements for spot trading.

Supports fundamental and harmonic metering and measurement, with up to 63rd harmonics.

2/3 RS485 channels and far-infrared communication interfaces, independent and supporting simultaneous multi-channel reading.

Records a wide range of grid and meter events.

Dual backup data storage with self-checking and error correction functions.

High-brightness backlit, wide-viewing-angle, high-durability LCD display.
