We support in modernizing your substation with our services for Automation and SCADA. We have worked and completed projects on all leading automation systems from reputed manufacturers like SIEMENS, Schneider, GE-Alstom and ABB. We also hold expertise in integrating IED’s of different makes into a SCADA system by using interoperability.

We have worked on below software:

1.     SIEMENS SICAM PAS
2.     SIEMENS WinCC
3.     SIMENS SICAM 230
4.     GE Alstom PaCiS
5.     Schneider ECO SUI

In most of the small- and mid-sized industries, processes are automated by means of industrial PLC. However, critical power assets like circuit breakers, relays, transformers, battery banks and other auxiliary switchgears, etc. are often not automated.All these important assets mostly work offline without getting monitored on a continuous basis and thus we fail to collect important data which could be utilised to maintain and operate the assets more efficiently.

Myths behind this scenario

Myth 1: Substation automation solutions are very costly as they do not justify their cost.

This is a most talked about myth in the industry. Initially, as solutions were designed to cater to mainly the utility sector which works on a very large scale, costs were higher. But now you can get a solution customised to meet the requirement of small- and mid-sized industries. All major OEMs now offer such solutions mostly with the help of their authorised partners/system integrators. Such partners or system integrators are equipped with expert level knowledge and also they have reduced overheads for engineering, manufacturing and services, making solution viable both technically and economically. Also, reachability and service availability has become better.

Myth 2: Substation automation is not necessary for our scale of industry as we can manage manually.

Let us accept the fact that while the world is moving, you cannot stay back. Sooner or later you have to catch up with new technology. Technology helps you to navigate in difficult times, e.g., consider the latest situation caused due to COVID-19 wherein industries need to work with reduced manpower. In such a scenario, if one has automation in place, then one can manage the uninterrupted power supply to their plants even with less men at work or you can even control things remotely. As in substation automation, you can monitor and control all your assets at one place.

We at DSG Enterprises, are working extensively to give our customer the flavour of substation automation technology at prices affordable to them without compromising on features.

GIS are getting more popular or say necessary in urban areas or Industries where space is constraint as GIS gives us unique advantage over conventional AIS in terms of saving lot of space.

This compactness is achieved by means of SF6 gas instead of Vacuum or Air.

So for doing Erection, Testing and Commissioning of GIS expertise lies in how one handles the Gas at site. For most of the GIS it is required to fill the gas at site after installation and this activity needs lot of expertise and sophisticated Instrument.

We have this distinct expertise of dealing with SF6 gas with our own equipment. The highly trained team of experts works with excellent coordination by virtue of their long on field experience to execute the job within deadlines.

Another challenge in GIS is, Relays used are advanced and also needs to be integrated with Substation automation system or SCADA. Often many holds only expertise of ETC of GIS. But we offer a complete ETC of GIS along with Configuration, testing and commissioning of Relay and SCADA .

Our team of experts can give you all kinds of ETC services for your substation. We can work all across the voltage levels LV,MV,HV and EHV. We carry out ETC for AIS as well GIS substations. We have our own advanced testing equipment to carry out necessary testing at substation and to get the work done quickly without depending on anybody.
