Chhattisgarh sits on the 765 kV evacuation backbone for central India. Steel complexes, captive thermal power and aluminium processing all share that backbone. Sub-synchronous oscillation, transient stability and protection coordination across long EHV transmission paths are not optional study types here - they are the engineering reality of operating in the corridor.
Brownfield Digital Engineering is not a service line - it is a posture. Below are the four decision-pillars the Raigarh practice carries.
EHV protection requires distance relay coordination across long lines, zone reach verification under 3-phase + LG faults, and CT/PT ratio audit. We re-derive settings in DigSILENT PowerFactory and verify against the prevailing CTU grid code revision.
Long EHV evacuation paths with series compensation are vulnerable to sub-synchronous oscillation. We model under PSCAD and verify the SSO envelope is bounded by damping.
Captive thermal generation, the steel plant utility, and the evacuation tie are one electrical system - even if they sit on three drawing-sets. We model them as one in ETAP, with the inter-tie coordination checked end-to-end.
Aluminium processing pulls reactive power and harmonics. We model the 765 kV impact, recommend filtering, and verify CEA Grid Code compliance.
A Chartered Engineering practice is defined by the standards it commits to. The Raigarh practice signs against the following codes, with the appropriate industry overlays applied per engagement.

VB Engineering(R) India Pvt. Ltd. operates a single Brownfield Digital Engineering practice. The seven disciplines below are delivered from the Raigarh office with CEng MIE FIE signature from the Hyderabad HQ.
IEEE 1584-2018 Arc Flash incident energy, Load Flow + Short Circuit, Protection Coordination, Transient Stability, Harmonics, Insulation Coordination, Motor Starting, Reliability, DC Arc Flash. ETAP, DigSILENT PowerFactory and PSCAD model build + audit + reconciliation.
Read the practice ->Tripod + drone capture across plant footprint at 6 mm registered accuracy. Pointcloud-to-CAD pipeline. Pre-LiDAR engineering brief and post-capture quality control owned by the practice. Handover-ready for Wistwin where the operator opts in.
Read the practice ->LiDAR-powered productized as-built. P+ID, isometric, GA, equipment layout, process and electrical drawings reconciled to plant reality. Drawing-set restored to a single source of truth. Ready for capex and shutdown planning.
Read the practice ->FlexSim discrete event simulation for manufacturing flow, terminal logistics, mining haulage, healthcare patient flow, airport passenger + baggage flow. Decision-grade animated models that surface the bottleneck before the capex commitment.
Read the practice ->HAZOP, QRA, LOPA, SIL, Bowtie, Consequence modelling. Aligned to IEC 61511, IEC 61882, IEC 60079, OISD-aligned for refining + petrochem scope. Independently reviewed and regulator-ready.
Read the practice ->5-year NFPA 70E recertification retainer. Annual training cycle. Bilingual labelling. PPEAI enforcement layer. Audit-ready handover packs for plant, insurer and regulator review. Recertification windows tracked from the day labels are installed.
Read the practice ->The 5-stage arc flash compliance program. Assess + Label + Train + Enforce + Renew. Delivered across 6 countries. The flagship Brownfield Digital Engineering productized service.
Read the practice ->CEng MIE India practice lead drafts the deliverable against the standards stack. Project file maintained from kick-off.
An independent Principal Reviewer (CEng MIE FIE MIET) who has not been part of the engagement team signs the deliverable. Two-sign discipline. Structural firewall.
Documentation handed back at audit-grade quality - regulator-ready, insurer-ready, capex-committee-ready. Project file archived.
A 765 kV switchyard built in 2008 was sized for a 2008 fault-current envelope. The corridor has added 6,000 MW of generation since then. The Raigarh practice exists to recompute that envelope honestly, recommend the protection updates required, and hand back EHV studies signed at the FIE Principal Reviewer level.
Three illustrative engagements with operator names withheld. Technical figures are representative of multiple engagements in the Chhattisgarh regional delivery zone.
Multi-train NFPA 70E + IEEE 1584-2018 recertification covering 132 kV intake, 11 kV distribution, large-motor starting analysis and arc flash labelling. Incident energy reduced from 16.4 to 5.8 cal/cm-squared. 5-year AMC retainer signed.
765 kV protection coordination + transient stability following a 1,600 MW capacity addition to the corridor. Distance reach verified. SSO envelope verified bounded. Principal Reviewer FIE signature.
LiDAR-captured pot line + auxiliary halls. P+ID reconciliation. Full PSS suite with harmonic filtering recommendation for 765 kV grid code compliance.
A Chartered Engineering practice is defined as much by what it refuses as by what it delivers. These are the four lines we hold.
Scope drives the proposal. Every engagement is scoped per facility and quoted in writing within 5 business days. There is no rate card on this site.
Photographs that appear on engineering pages are real plant work the practice has been part of. We do not synthesise refinery skylines or fictional control rooms to look impressive.
Every drawing, study and report that leaves the practice carries two signatures - the drafting Practice Lead and an independent Principal Reviewer. This is not negotiable.
If the scope changes mid-engagement, we re-scope and re-quote. Hidden scope creep is not how a Chartered Engineering practice operates.
The Raigarh delivery zone covers the following industrial clusters and corridors. Engineering work is scoped per facility - travel to site, plant access discipline and shutdown-window coordination are all part of the engagement.
Tell us the service, the operational decision and the timeline. A practice lead will respond with a written scoping note within one business day.
