1.1. GENERAL DESCRIPTION
The SMOR system is a microprocessor based multifunction protection, control and measurement unit. The
SMOR uses a set of algorithms to create a general purpose protection and monitoring unit for power
systems.
The SMOR system is supplied in a 19’’ rack case 2 units high. Figure 1 shows a diagram for panel drilling
installation.
All the information and settings of the unit are accessible by means of a computer connected to the serial
port (RS232 or fiber-optic) or using the man-machine interface (MMI), which includes a 20 character keypad
and a two line liquid crystal display (LCD) with 16 character on each line, located on the front of the relay.
This protection system includes the following functions:
a) Protection:
•
6 overcurrent units arranged in the following way:
- 3 phase units:
- 51PT, Instantaneous, Inverse or definite time.
- 50PH, Instantaneous or definite time.
- 50PL, Instantaneous or definite time.
- 3 ground units:
- 51NT, Instantaneous, Inverse or definite time.
- 50NH, Instantaneous or definite time.
- 50NL, Instantaneous or definite time.
•
Independent directional supervision adjustment for each overcurrent functions.
•
Negative sequence overcurrent
•
Three-phase over and undervoltage
•
Ground overvoltage (2 levels). NOTE: Only for the SMOR7000 model an open delta input is available.
•
Over and under frequency
b) Monitoring and Register
•
Current measurement for each phase and ground.
•
Negative sequence current measurement.
•
Measurement of line to line voltages.
•
Measurement of active and reactive power along with power factor.
•
Frequency measurement.
•
Breaker status.
•
LED indicators - 17 LED display (16 of which can be configured by the user).
•
Breaker supervision for failure-to-open or failure-to-close (optional, mounted in the additional board).
•
Breaker health monitoring (
Σ
I2 t) per phase.
•
Phase rotation sequence selection (ABC or CBA).
•
Maximeter for current and active power.
•
Built in self-checking unit.
