25 marquee operators across 21 countries trust VB Engineering.
Arc Flash, Load Flow, Short Circuit, Protection Coordination, Transient Stability, Harmonics across Indonesia. Jakarta operations. PUIL 2011 + SNI + K3 Migas + IEEE 1584 + NFPA 70E multi-standard practice. Chartered Engineer (CEng MIE India) signature.
VB Engineering Indonesia delivers the full Power System Studies stack from the Indonesia operations across Pertamina + Medco + Saka upstream and refining, PLN grid infrastructure, Freeport-McMoRan mining operations, and broader Indonesian industrial estate. PUIL 2011 (Indonesian General Electrical Installation) + SNI (Indonesian National Standards) + K3 Migas (oil & gas safety) + IEC 60909 + IEEE Std 141 (load flow + fault) + IEEE Std 242 (coordination) + IEEE 1584 + NFPA 70E (arc flash). Chartered Engineer (CEng MIE India) signature accepted by PII + Migas. Bahasa Indonesia-English bilingual delivery.
Load flow, short circuit, arc flash, protection coordination, transient stability, and harmonics studies delivered with a Chartered Engineer signature on every page, for the the Cilacap refining (Java) that Indonesia operates.
Across Pertamina's refining estate, the Bontang and Tangguh LNG complexes, and the Morowali-Weda Bay nickel-EV-battery processing build-out, power-system studies are what make a brownfield retrofit defensible. Indonesia's industrial electrical engineering market is led by Pertamina's refining and petrochemical assets, the gas-processing and LNG complex (Bontang · Tangguh · Donggi-Senoro), and a fast-growing nickel-laterite to electric-vehicle-battery processing build-out (Morowali · Weda Bay). PUIL 2011 (Persyaratan Umum Instalasi Listrik · the Indonesian wiring rules) and Migas regulations drive the regulatory framework. Indonesia's industrial base was largely built between 1985 and 2010. Pertamina's refining modernisation program (Cilacap · Balikpapan · Dumai) is brownfield expansion. The Morowali / Weda Bay nickel-EV-battery build-out is a brownfield extension of an existing industrial corridor. The brownfield digital engineering offer fits the country's posture directly.
Every deliverable is mapped against PUIL 2011 (general electrical installations) · SNI IEC 60079 (hazardous area) · SNI IEC 61936 · IEC 60909 · Migas K3 (occupational safety) regulations. Where the operator references additional standards, we engineer in parallel against IEEE 1584 (arc flash) · NFPA 70E (referenced in Pertamina HSE standard) · PLN distribution standard for grid-tied loads · BKPM and ESDM licensing framework. The conformance matrix on page one of the report calls each section against the relevant clause so Direktorat Jenderal Migas (K3 Migas) · PLN (state electricity) review the deliverable in the format they expect.
Steady-state load flow under base, contingency, and N-1 conditions. Voltage profile mapped across 380 V / 400 V to 380 V / 400 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 PUIL 2011 + IEC 60909. Breaker rating reconciliation against the as-installed equipment fleet at Pertamina Cilacap refinery. 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 + PUIL 2011 labels in Indonesian-English expects.
Time-current curves graded for selectivity across 380 V / 400 V to 380 V / 400 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 Indonesia grid-code requires fault-ride-through, we model against the published curve.
Harmonic measurement at the PCC against IEC 61000-3 + PLN connection limits. 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 equatorial year-round thunderstorm exposure), the surge protection package covers the equipment fleet directly.
Three Indonesian engagements (a Pertamina refinery, a Bontang-region LNG train, and a Morowali nickel processing plant) that show the pattern:
a 348,000 BPD refinery with 150 kV intake and aging 11 kV switchgear.
The engagement: K3 Migas safety audit demanded current arc flash labels in Indonesian language; full plant re-baseline + protection coordination + PUIL 2011 conformance package.
an LNG train with 70 kV intake and 6.6 kV distribution.
The engagement: Insulation coordination after lightning event on the 70 kV feeder; SPD selection + ground grid reconciliation + harmonic measurement.
a HPAL hydrometallurgy plant with 150 kV captive coal-power + 11 kV processing distribution.
The engagement: First-of-kind plant arc flash baseline against international standards while satisfying PUIL 2011 and K3 Migas review.
