PAS Launches Online Harmonic Current Sensor
Created on Today
As nonlinear loads become increasingly common in power grids, harmonic pollution has grown more severe.
To simplify the measurement of current harmonics in power grids, PAS has introduced a distributed, networkable, integrated harmonic current measurement sensor that can directly measure harmonic content without requiring an external primary current transformer. The sensor conveniently measures harmonic components of grid current and can be networked via an RS485 interface.
The JID-C30-PQM Series harmonic current measurement transmitter innovatively employs an industrial-grade System on Chip (SOC) and advanced FFT algorithm. Key features include:
