1.1. GENERAL DESCRIPTION

The MOV system is a digital multifunction unit for protection, control, and measure, using a group or

algorithms that allow the implementation of different voltage functions, described on section 2 of the present

instruction manual.

The MOV system is housed in a 19'' 2 units high rack. Figure 1 shows the panel drilling dimensions.

The information and functions management can be performed with a PC connected to the serial port

(RS232 or fibre optic), or using the man-machine interface (MMI), that includes a 20 key keypad and an LCD with

two rows of 16 characters each, on the front of the unit.

The functions included in this system are as follows:

a) Protection:

• Undervoltage functions (A, A').

• Voltage absence functions (B, C, D).

• Voltage presence functions (E, F, J).

• Weak infeed functions (G, H, I).

• Closing and reclosing permission functions for two breakers.

b) Monitoring and Registering:

• Three-phase line voltage, busbars 1 &2 voltage measurement

• Associated line selector switch status.

• Optical signalling with 17 LED indicators (16 configurable).

• Self-check.

c) Analysis:

• Event recording.

• Oscillography recording.

d) Control:

• 3 settings tables.

• Time synchronization using communications, or IRIG-B.

• Configurable inputs and outputs.

• User configurable internal logic.

e) Communications Interfaces:

• Local and remote communications using three connectors, one on the front and two on the rear of the unit.

• Manual interface (MMI) with keypad and alphanumeric display.

•

GE-INTRO configuration software and GE-LOCAL communications software, Windows

software packages are part of the GE-NESIS (GE NEtwork Substation Integration System).
