The electrical power system is the backbone of every process plant — determining not just whether a facility can operate, but whether the plant can operate safely, reliably, continuously, and within the envelope that protects people and equipment across every condition the system will encounter. Inadequate power system analysis carries real consequences: protective devices operating out of sequence, undersized circuit breakers, and switching overvoltages exceeding insulation limits. These are recurring outcomes, not theoretical risks.
JEF delivers two complementary categories of power system analysis, covering both system-wide behaviour and high-frequency transient phenomena:
• Power System Studies - Steady-state and dynamic analysis using ETAP, PSS®E, DIgSILENT PowerFactory and SKM for Load flow, short circuit, Motor starting, Harmonic analysis, Protection coordination, Arc flash assessment, Transient stability & Load shedding studies
• Electromagnetic Transient and Insulation Coordination Studies - High-fidelity time-domain simulation using PSCAD/EMTDC: Switching overvoltages, Temporary Overvoltages (TOV), Transient Recovery Voltage (TRV), Fast Transients (FTO / VFTO), Ferroresonance, Transformer energisation.
EMC management plan, desktop survey, zone allocation, remedial measures, includes subsea cable interference to pipelines and cathodic protection systems. EMC compliance certificates issued on completion.
Substation earthing grid design, step and touch potential analysis, personnel safety verification.
Risk assessment and protection system design for process plants, substations, and offshore platforms.
Thermal rating and sizing of HV cables including 132kV and 33kV submarine cables.
Shunt reactor specification and sizing for reactive compensation on long cable systems.
Selection and placement of surge protective devices across all voltage levels.
Dynamic modelling of tap changer and AVR behaviour, including stability control interaction.
EM fields from subsea cables and interaction with adjacent pipelines, structures, and control systems.
Grid-scale modelling for dynamic stability and HVDC converter studies.
From ETAP-based steady-state studies to PSCAD electromagnetic transient analysis, we deliver the complete study programme end-to-end — with one team responsible for both the analysis and the engineering outcomes.
ETAP, PSCAD/EMTDC, PSS/E, DIgSILENT, SKM, and DSA Tools — no software constraint on what we can offer or how we work.
Offshore platforms, subsea cables, high-voltage GIS, complex multi-source networks. We know the operating environment and the standards that govern it.
Every finding traceable to the specific standard clause that defines the requirement.
We identify constraints and failure modes beyond standard studies, providing the project team with a complete picture before decisions become irreversible.
