AI Technical Summary
Existing automatic quasi-synchronous information acquisition circuits are not accurate when there is high harmonic content or waveform distortion, and traditional circuits are prone to introducing errors, making troubleshooting time-consuming and prone to misoperation.
It adopts a three-phase power bus, voltage transformer group and secondary acquisition circuit, and configures an angle transformer for phase correction. It features independent branch design and a shared grounding system. The auxiliary monitoring unit displays voltage, frequency and phase difference in real time, and realizes synchronous signal acquisition and calculation through a common terminal group.
It improves the accuracy of phase acquisition, reduces errors, enhances system stability and anti-interference capabilities, simplifies troubleshooting, and reduces maintenance time.
