Manufacturing for MOV has been discontinued.

The MOV is a digital multifunction protective relay that provides undervoltage, voltage absence, voltage presence, and closing and reclosing permission functions for two breakers. It offers a great flexibility of configuration for the definition of inputs, outputs and internal logics. The MOV includes analysis functions, such as event recording, oscillography recording, and an alarms panel.

Applications

• Complex substation busbar schemes

Protection and Control

• Undervoltage
• Voltage absence
• Voltage presence
• Weak infeed
• Closing/reclosing permission

• 3 settings tables

Monitoring and Metering

• Three-phase line voltage, busbars 1 & 2 voltage measurement
• Associated line selector switch status
• Optical signaling with 17 LED indicators
• Event recording
• Oscillographic record

User Interface

• RS232 port, faceplate accessible
• RS232/fiber optic/RS485 ports, rear accessible (see model list)
• HMI with keypad and alphanumeric display
