Puncture-mounted power meters can measure single-phase or three-phase loop power grid parameters, including voltage, current, power, frequency, energy, demand, limits, total harmonic distortion, 2-31 harmonic content, voltage and current imbalance and other parameters. The meter adopts the open current transformer access method, which supplies power to the entire instrument and measures the full power parameter through the puncture method. The product can be installed without interrupting power. The instrument communication can use LoRa wireless or RS-485 interface, and the communication protocol adopts ModBus-RTU Protocol.
