Substation Automation Services

Retrofitting and Upgradation Services

As they say change is only constant thing and your substations are no exception to that. With change in technology or due to end of product life-cycle we need to keep upgrading our assets. We support in doing retrofit of Relays with either one to one replacement or by using advance version relays. Also we do up gradation of your old SCADA with new hardware or software or both.

Our Services Includes:

1. Replacement of old Electromechanical Relays with Numerical Relays

2. Replacement of Outdated Numerical Relays with Latest Models

3. Up gradation of existing SCADA system

4. Integration of additional Devices into existing SCADA

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.
