Digital Protection Relay

This detection device constantly monitors leakage current value through the control DC power supply line (P phase/N phase) through the communication type current transformer (DCT), and serves as detection device with alarm output and fault history storage for each channel in case of DC leakage.

• • Computational Digital Monitoring Device
• • Detection method selection for each channel
• • Signal measurement using communication-type DCT
• • Easy expansion and selection of channels
• • Noise elimination measurement method
• • Monitoring control using external interface
