With the increasing application of nonlinear loads in power grid, the harmonic wave pollution of power grid is becoming more and more serious.
In order to simply measure the harmonic wave of the current in the power grid, PAS launched a distributed, networked and integrated harmonic wave current measurement sensor that can directly measure the harmonic wave content without connecting a primary transformer, which can conveniently measure the harmonic wave component of the power grid current and form a network through RS485 network connection.
JID-C30-PQM series harmonic wave current measurement transmitter innovatively adopts industrial SOC (system on chip) and advanced FFT algorithm, with the following characteristics:
Current Range: AC 0-500A,
Power Supply:DC24V,
Accuracy: ≥ 0.5%,
Output parameter：Fundamental current, 2-50th harmonic wave current, ITHD, etc.
Perforation size: φ 42mm,
Output signal: RS485,
Signal protocol: Modbus RTU,
Baud rate: 1200, 2400, 4800, 9600, 19200 can be set.
