Electrical infrastructure for industrial operations
Power systems in mining, sugar and manufacturing environments are not like commercial installations. The loads are larger, the consequences of failure are more expensive, and the environments are harder on equipment. Getting the design right from the start matters.
We engineer power systems that are correctly sized for current and future load, protected against realistic fault conditions, and maintainable by the site electrical team without needing specialist support for routine work.
What we design and integrate
Transformer installations - selection, civil and structural interface, protection relay schemes, and commissioning. We specify transformers to match your load profile and site conditions, and design the associated switchgear and protection to coordinate correctly.
HV and LV switchrooms - switchroom layout, busbar design, protection coordination, and earthing systems. Whether you’re building a new switchroom from scratch or upgrading an existing one, we produce the engineering package required for fabrication and installation.
Motor control centres (MCCs) - MCC specification and design for motor-heavy processing applications. Starter selection, protection sizing, and integration with your control system.
Protection relay schemes - overcurrent, earth fault, differential and distance protection for MV and HV systems. We design protection to discriminate correctly under all fault conditions and coordinate with your network service provider’s upstream protection.
Earthing and lightning protection - earthing system design to AS/NZS 3000 and AS 2067 for HV installations. Earth grid design, step and touch potential calculations, and lightning protection for exposed structures and equipment.
Power factor correction - assessment of reactive power demand and design of correction systems. Fixed and automatic correction banks sized to your load profile, with harmonic filtering where required.
Power quality - site assessment for voltage fluctuations, harmonics, and power quality issues. Identification of root causes and engineering of corrections, including filters, voltage regulators, and load management approaches.
Typical projects
New processing lines or equipment additions where the existing supply infrastructure needs to be assessed and upgraded to carry the additional load. Switchroom replacements where ageing equipment has reached end of life and a like-for-like swap is not adequate. Power quality investigations on sites where unexplained equipment failures or nuisance tripping is affecting production.
We also work regularly on shutdown projects where power system work needs to be planned, engineered and executed within a fixed outage window - a constraint we understand and design around from the start.
Engineering documentation
Every power system project is supported by engineering documentation - load schedules, protection relay settings, single-line diagrams, and commissioning records. These are produced to RPEQ standard and handed over at project completion so your team has accurate records of the installed system.
