Product Overview
The indoor zero-phase-sequence integrated voltage sensor is an intelligent sensor that integrates three-phase voltage measurement and zero-sequence voltage detection. It is designed for power system monitoring, relay protection and power quality management. Through high-precision signal acquisition and integrated processing, it outputs three-phase voltage amplitude, phase and zero-sequence component in real time. It is suitable for distribution automation, new energy grid connection, industrial power monitoring and other scenarios, helping users to achieve safe and efficient operation of the power grid.
