If
the project encompasses large area to be surveyed and human
surveillance in not possible in such case, then one needs long distance
SACDA radio networks to be employed for sending the data collected from
remote sensors to central unit.
When area under surveillance is hundreds of kilometres such as in case
of petroleum pipeline, the only feasible solution is long distance
Scada GSM. Most important requisite for long range Scada GSMs
is ability to transmit the data to long distance.
For such purposes, repeaters are used as line of sight is limited to 5
miles. Repeaters are radio transmitters which act as boosters for
signals as signals tend to get weak after travelling certain amount of
distance. Thus repeaters boost the attenuated signals and again
transmit them to next repeater/ central system.

SCADA systems (Supervisory Control and Data Acquisition Systems) have
altogether revolutionized the way of doing automated tasks and
increasing the efficiency with which they get performed. Being closed
loop systems they require minimal human intervention and can perform
most of changes continuously without any need of human to intervene.
So effective SCADA systems have been proved that now they are not being
employed not only at factories but also in many types of control
systems mainly being electricity control system (both traditional and
nuclear), water control systems, sewerage control systems etc. The
basic principle for SCADA systems is the collection of data at specific
intervals of time and after the collection, sending the data collected
from these sensors to a central unit. |

Scada in the electricity industry
No one can doubt the way, SCADA systems have transformed the way
automated tasks were use to get performed. Just due to SCADA systems,
various automated tasks have become more reliable and
efficient.
As these systems don't require or a very little human intervention and
are able to handle most of impermissible states, they have also cut the
costs of maintenance and trouble shooting. Due to high degree of
reliability, efficiency and flexibility, these SCADA systems have found
themselves in almost most every realm of automated tasks.
SCADA systems are now widely used in control systems (like water
control systems, sewerage control systems) or even in daily equipments
like water metering pumps. The extent to which automated tasks have
become dependent on SCADA systems cab be judged from this fact that
SCADA in the electricity industry has become a necessity.
