GENERAL DESCRIPTION AND APPLICATION
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, Windowsäbased. Both
software packages are part of the GE-NESIS (GE NEtwork Substation Integration System).

OPERATION PRINCIPLES
2.1. PROTECTION FUNCTIONS
The MOV general connections diagram, and the external voltage commuting required is shown on the
following diagram:
2.1.1. A FUNCTION
=V1*(V2*89+(V3*V4*V5)*89)*TMP
where:V1 = Undervoltage on bus 1.
V2 = Undervoltage on bus 2 (or line 2)
V3 = Undervoltage on line phase A.
V4 = Undervoltage on line phase B.
V5 = Undervoltage on line phase C.
89 = Line Selector switch closed.
89 = Line Selector switch open.
* = logic AND.
+=logicOR.
TMP = time setting for function A.
This function consists on detecting undervoltage (1.1. setting) on both sides of the side breaker (in case of
breaker and a half schemes), during a certain period of time (setting 2.1.). It monitors the Busbar voltage (V1) and
the line voltage values (V3, V4, V5) or V2, depending on the status of the line disconnection switch. The operation
of this function allows the side breaker to trip and signal undervoltage to the control system.
2.1.2. FUNCTION - A’
=(V1*89+(V3*V4*V5)*89)*TMP’
This function detects undervoltage (setting 1.1.) on the line side associated to the central breaker. In order
to monitor undervoltage on both sides of the central breaker, this function needs to be ANDed with function A’ of
the MOV relay protecting the other two breakers (contacts in series).
