 SCADA
systems, (supervisory, control and data acquisition), play a vital
role in the operation of electricity utilities. SCADA systems
are used to monitor and control their equipment, which is usually
spread over a large geographical area. They have to gather information
from a number of field RTU’s (remote terminal units) over a variety
of communications links, and present the information in a clear
and concise way to the operators. While implementing SCADA systems
enhance utilities’ performance, they also face a number of challenges
- installation in harsh electrical and physical environments,
rapidly evolving technology and short product life spans, data
overload, and a shortage of skilled resources in the industry.
Since 2000, Virelec has developed its capability to supply SCADA
systems in a number of areas, and is a VAR (value-added reseller)
for the GE Energy Systems platform. We specialize in the applications
described below, providing design, assembly, configuration, testing
and commissioning services.

Distribution
Automation: The supply of DART’s
(Distribution Automation Remote Terminals), mounted on pole-tops
to monitor and control motor-operated distribution switches.
Electricity Market Participation:
The supply of compliant interfaces to extract, concentrate,
and transmit data from the substation to the system operator
using approved communications equipment and protocols.
Substation Control Systems:
The supply of complete substation control systems, which concentrate
and use data from substation IED's, instrument transformers,
transducers and hard-wired inputs to implement the local and/or
remote control of the substation.
