25 marquee operators across 21 countries trust VB Engineering.
Arc Flash, Load Flow, Short Circuit, Protection Coordination, Transient Stability, Harmonics across Australia. Perth channel partnership. AS/NZS 3000 + AS/NZS 4836 + IEEE 1584 + NFPA 70E multi-standard practice. AusIMM reference framework.
VB Engineering Australia delivers the full Power System Studies stack via the Perth channel partnership across mining + minerals processing operations in the Pilbara + Goldfields + Bowen Basin, LNG facilities on the North West Shelf, and the broader Australian industrial estate. AS/NZS 3000 (Wiring Rules) + AS/NZS 4836 (Safe Working on LV electrical installations) + IEC 60909 + IEEE Std 141 (load flow + fault) + IEEE Std 242 (coordination) + IEEE 1584 + NFPA 70E (arc flash) + AusIMM reference framework. Chartered Engineer (CEng MIE India) signature accepted.
For brownfield Pilbara iron ore train load-out and process plant in Australia: load flow + short-circuit + arc flash + coordination + transient + harmonics, signed by a Chartered Engineer (CEng MIE FIE) who walked the plant.
Across the Pilbara iron-ore corridor, the North West Shelf LNG belt, and the east-coast critical-minerals build-out, power-system studies are what make a brownfield retrofit defensible. Australia's industrial electrical engineering market is anchored by Pilbara iron ore (Rio Tinto · BHP · FMG), the LNG west coast (Karratha · Onslow · Darwin), east coast coal-seam-gas to LNG (Gladstone), and a growing critical-minerals processing build-out. Worksafe enforcement under AS/NZS 4836 (Safe working on low-voltage installations) is the primary driver of arc flash baseline work. Australia's mining and LNG cycles built most of the existing industrial electrical asset between 2005 and 2018. The next decade is operating-cost extraction from that asset base · and the operating side is where every brownfield engineering hour matters.
Every deliverable is mapped against AS/NZS 3000 (wiring rules) · AS/NZS 3008 (cable selection) · AS/NZS 4836 (safe working LV) · AS/NZS 60079 (hazardous area) · AS/NZS 3017 (testing) · AS/NZS 3007 (mining electrical). Where the operator references additional standards, we engineer in parallel against IEEE 1584 (arc flash · referenced in AS/NZS 4836 commentary) · IEC 60909 · AEMO grid code for grid-tied generators · WA Department of Mines, Industry Regulation and Safety (DMIRS) electrical-safety requirements. The conformance matrix on page one of the report calls each section against the relevant clause so Worksafe (state-based) · DMIRS WA (mining and energy safety) review the deliverable in the format they expect.
Harmonic measurement at the PCC against AS/NZS 61000-3 + AEMO grid code. Spectrum capture at every drive load. Filter design where the PCC distortion is outside limit. Measurement campaign with a calibrated PQ analyser is included.
BIL coordination across the voltage levels. Surge-arrester selection at the intake. SPD class-by-class selection at LV distribution. Where lightning exposure is documented (a recurring driver for Pilbara summer storm season), the surge protection package covers the equipment fleet directly.
Steady-state load flow under base, contingency, and N-1 conditions. Voltage profile mapped across 415 V to 415 V. Tap-position recommendations for transformer LTCs. The deliverable closes any voltage-regulation finding from the previous study or insurer walk.
Three-phase, line-to-line, and single-line-to-ground fault calculations to AS/NZS 3008 + IEC 60909. Breaker rating reconciliation against the as-installed equipment fleet at Pilbara iron ore train load-out and process plant. Asymmetrical current and X/R ratio captured at every bus.
Incident energy at every working position, calculated to IEEE 1584-2018 (the 2002 method is retired in our practice). Arc flash boundary, restricted approach, and PPE category by bus. Labels print in the format IEEE 1584 + AS/NZS 4836 labels in English expects.
Time-current curves graded for selectivity across 415 V to 415 V. Setting workbook in the format your AMS accepts. Where coordination drift is identified against the as-found CT/PT ratios, we rebuild the recommendation from the most upstream device down.
Motor-starting voltage dip during simultaneous restart, generator stability under fault clearance, and ride-through during voltage-recovery events. Where the Australia grid-code requires fault-ride-through, we model against the published curve.
Three Australian engagements (Pilbara iron-ore, NWS LNG, and a critical-minerals refinery) that show the pattern:
an 80 MTPA ore-handling plant with 33 kV ring main and ball-mill drive train.
The engagement: DMIRS reportable incident on the ball-mill MCC arc flash event; full plant re-baseline against AS/NZS 4836 + Worksafe expectations + protection re-grading.
an LNG train with 132 kV intake and electric-drive refrigeration.
The engagement: NOPSEMA safety-case revision triggered full electrical-safety review; arc flash + insulation coordination + ground grid reconciliation across the train.
a lithium hydroxide refinery with 33 kV intake and 6.6 kV distribution.
The engagement: Insurance underwriter required arc-flash baseline before policy bind on the first-of-kind plant; IEEE 1584 study + AS/NZS 4836-aligned labels.
