Home/Services
Three disciplines, one engineering team.
The engineer who prepares the coordination study is in the same team as the engineer who verifies the scheme on site. That is the whole point of how we're organised.
Testing & Commissioning
Pre-commissioning and charging of EHV substations and their equipment — transformers, circuit breakers, isolators, CTs, PTs and protection schemes — with calibrated instruments and traceable reports.
- Insulation resistance & tan delta
- Breaker timing & dynamic contact resistance
- Relay calibration & scheme verification
- GIS testing up to 765 kV
Operation & Maintenance
We take over live substations and transmission lines from 33 kV to 400 kV and keep them available — scheduled inspections, predictive diagnostics, shutdown execution and breakdown response, with the reporting discipline utilities expect.
- Substation O&M, 33–400 kV
- Transmission line O&M
- Shutdown planning & execution
- Condition monitoring of HV assets
Power System Studies
Load flow, short circuit and protection coordination studies in ETAP — the analytical layer behind safe, code-compliant operation. We model source to load and hand over coordinated relay-setting documents with grading curves.
- Load flow analysis
- Short circuit studies
- Protection coordination & relay settings
- Root cause analysis of failures
Voltage classes we work at
From 33 kV panels
to 765 kV GIS.
Every class below is work we've actually executed — not a capability statement. The higher you go, the fewer contractors can hold the schedule. We hold it.
Panel and switchgear testing on industrial and mining networks. Failure investigation on distribution systems.
Substations executed for a state transmission utility.
O&M of pooling substations evacuating utility-scale renewable generation.
Substation and GIS testing across multiple states, including interstate transmission projects.
GIS testing and commissioning — the highest voltage class on the Indian grid.
Resources
The instruments
we own.
Most contractors write "state-of-the-art equipment from reputed brands." Here is the actual list. It answers the question a technical evaluator is really asking — whether we can execute your scope with our own resources, or will be hiring instruments when the shutdown window opens.
| Instrument | Make & model | Used for | Calibration |
|---|---|---|---|
| Primary injection set | make / model | CT saturation, primary current tests | cal. status |
| Secondary injection / relay test set | make / model | Relay calibration, scheme verification | cal. status |
| Circuit breaker analyser | make / model | Breaker timing, travel, DCRM | cal. status |
| CT / VT analyser | make / model | Ratio, polarity, burden, magnetisation | cal. status |
| Tan delta / capacitance kit | make / model | Insulation condition of bushings and CTs | cal. status |
| Insulation resistance tester | make / model | IR and polarisation index | cal. status |
| Winding resistance meter | make / model | Transformer winding resistance | cal. status |
| Turns ratio tester | make / model | Ratio and vector group | cal. status |
| Earth resistance tester | make / model | Earth mat and electrode resistance | cal. status |
| Thermal imaging camera | make / model | Hot-spot detection during O&M | cal. status |
| SF6 gas analyser / handling | make / model | GIS commissioning and maintenance | cal. status |
Calibration certificates are issued against traceable standards and travel with the crew to site. Certificates for any listed instrument are available on request.

People on the ground.
Utilities ask for this at pre-qualification anyway. Stating it up front saves a round of correspondence.

Who we work for
Utilities, PSUs
and EPC majors.
Our work reaches the grid through the contractors and developers who build it, and directly through the transmission companies who own it. Client names and project references are provided on request, subject to their consent.
