carrier spread-spectrum technology on the basis of Chinese power grid situations, according to the standard
of DL/T 698-1999. Taking the new generation of carrier communication chip as the core, this watt-hour meter
is featured with high integration, stable and reliable data t ransmission, high rate of success in communication,
convenient installation and maintena nce, etc.
1. Energy measurement
It can measure the forward and reverse electric quantity, display the measurement and accumulation of reverse energy and forward energy, also can indicate the reverse energy amount. Meanwhile, it can prevent the electricity being theft by reversing the current.
2. Detection interface
There is a detection terminal of photoelectric isolation and pulse output, for checking the meter and collecting the energy.
3. Communication function
The power line carrier communication is realized by the software spread-spectrum mode, with high accuracy and reliability and strong reading stability. It supports the reading and frozen data by the low voltage power line carrier
communication mode or performs the real-time reading of active power and watt-hour meter constants.
4. Relaying function
Mutual automatic relaying function
