Industrial Engineering Services for Plants and Manufacturing Facilities
Industrial engineering services at Trivonix focus on the electrical and utility backbone of operating plants — the distribution systems, protection schemes and supply capacity that everything else in a facility depends on, and that typically evolved through fifteen years of incremental additions rather than through a plan.
That history is the usual reason a plant cannot accept a new production line, a solar array or a fleet charging depot without work. Our job is to establish what the existing system can actually carry, and what the cheapest credible route to the required capacity looks like.
What this service covers
- Measured, not assumed
- Load studies based on recorded interval data and site verification, not on nameplate ratings added together.
- Designed around production
- Work packaged around shutdown windows and shift patterns so the plant keeps running.
- Documentation you can use
- Updated single line diagrams and cable schedules that reflect the plant as it actually is.
Power distribution design and upgrades
Plant distribution systems accumulate. A panel added for one line, a sub-distribution board for another, a transformer sized for a load profile that no longer exists. Individually each addition was reasonable; collectively they often produce a system with unbalanced loading, inconsistent protection grading and no accurate record of what feeds what.
- HT and LT distribution design, from the incoming supply through transformers, main panels and sub-distribution.
- Transformer sizing and loading assessment, including headroom for planned expansion.
- Switchgear specification, replacement and retrofit where existing gear is obsolete or unsupported.
- Cable sizing, routing and containment design, with voltage drop and derating properly applied.
- Standby generation and changeover schemes, including load prioritisation during a supply failure.
- Earthing and lightning protection design and verification across the site.
Load studies and capacity assessment
The most common question we are asked is whether the plant has capacity for something new. The most common way it is answered wrongly is by adding up connected loads, which overstates demand substantially and can trigger an unnecessary supply upgrade costing many times the study.
How a proper load study is built
Recorded interval demand data over a representative period, verified against the actual connected load and diversity by department, segmented by shift and season, and analysed for peak demand events rather than average consumption. That gives real headroom rather than theoretical headroom.
What it is used for
Sizing a supply upgrade correctly, negotiating a contract demand with the utility, determining whether new equipment can be accommodated, assessing solar or storage integration, and identifying whether demand charges can be reduced by load scheduling alone.
Protection coordination and system studies
Protection coordination is one of the least visible and most consequential parts of industrial electrical engineering. When it is wrong, a fault on one machine trips the incomer and takes down the plant — and often nobody investigates further than resetting the breaker.
- Short circuit studies to establish fault levels at each point in the system and confirm equipment ratings are adequate.
- Protection coordination and discrimination studies, so the device nearest the fault operates first and upstream devices hold.
- Relay setting calculations and setting sheets, with verification during commissioning rather than settings left at factory defaults.
- Arc flash assessment and labelling where the client's safety regime requires it.
- Harmonic and power quality assessment where variable speed drives, welding loads or non-linear equipment are present.
Power quality and energy efficiency
Poor power quality is expensive in ways that rarely appear on an invoice: overheated transformers and cables, nuisance tripping, premature motor failure, and process equipment behaving inconsistently for reasons nobody can pin down.
We assess power factor, harmonic distortion, voltage unbalance and transient events using logged measurement rather than snapshot readings, and specify remediation — correction equipment, filtering, or load redistribution — against what the measurement actually shows. Correction equipment installed without measurement occasionally makes harmonic problems worse rather than better.
Documenting the plant as it is
Almost every industrial engineering engagement includes a documentation component, because almost every operating plant's drawings are out of date. That is not a criticism of the client — it is what happens when changes are made under production pressure over many years.
Where we survey and verify a distribution system, we issue updated single line diagrams, panel schedules and cable schedules reflecting what is actually installed. That documentation typically pays for itself on the next fault, the next audit or the next project, whoever executes it.
Frequently asked questions
How do I know whether my plant has electrical capacity for new equipment?
Through a load study based on recorded interval demand, not by adding connected load ratings. Connected load overstates real demand because equipment does not run simultaneously at full rating. A measured study frequently reveals headroom that a nameplate calculation says does not exist — and occasionally reveals a constraint that a nameplate calculation missed.
What is a protection coordination study and why does it matter?
It calculates fault levels throughout the electrical system and sets protective devices so the device closest to a fault operates first while upstream devices hold. Without it, a fault on one machine can trip the main incomer and shut down the whole plant. It also confirms that installed switchgear is rated for the fault current it could actually see.
Can electrical upgrades be done without shutting down production?
Often partially. Cable routes, new panels, containment and terminations can usually be prepared while the plant runs. The tie-in itself normally needs an isolation window, but that window can be made short through prefabrication and pre-testing. Scheduling the tie-in around planned maintenance shutdowns is usually the least disruptive route.
What causes nuisance tripping in industrial installations?
Common causes include protection settings that were never coordinated, earth leakage accumulated across many drives and filters, harmonic currents from variable speed drives, and undersized or ageing devices operating near their limits. Diagnosis needs logged measurement during the tripping conditions — snapshot readings taken afterwards usually show nothing.
Do you work on plants where the existing drawings are inaccurate?
Routinely — it is closer to the norm than the exception. We survey and verify the installation rather than designing against unverified records, and issue updated single line diagrams and schedules as part of the deliverable. Designing against out-of-date drawings on a live site is how clashes and outages happen.
