Industrial sites have unique exposure to voltage transients. Heavy machinery, long cable runs, outdoor switchgear, and three phase equipment all increase the chance that a surge will find its way into sensitive controls. Our Industrial Surge Protection Services deliver robust, coordinated defence for factories, warehouses, and processing plants so you can protect production, staff safety, and critical infrastructure.
The business case is compelling. A transient that takes down a variable speed drive, PLC, or industrial chiller can halt operations and trigger costly scrap, missed deadlines, and overtime. Repeated smaller spikes reduce mean time between failures, raising maintenance spend and eroding uptime targets. By installing coordinated surge protection you stabilise your electrical environment, extend asset life, and support continuous improvement goals on reliability, energy, and safety.
We explain the technical side in plain language. Type 1 devices at the service entrance handle the highest energy events, including indirect lightning. Type 2 protection at distribution boards clamps the majority of everyday overvoltages moving around the plant. Type 3 units sit close to sensitive loads for final stage protection. Proper earthing and bonding are critical, as is keeping connection leads short and straight to avoid inductive overshoot. For sites with external structures, conveyors, or long sensor loops, we also assess data line and instrumentation protection so that surges do not travel on comms cables.
Our delivery path is methodical. Step 1: Site survey, including review of switchboards, sub distribution, earthing arrangements, lightning exposure, and critical processes. Step 2: Design and device selection, ensuring coordination across types and phases and allowing for future expansion. Step 3: Installation, planned around shutdown windows or live changeovers where appropriate, with clear labelling and as built drawings. Step 4: Commissioning and verification, capturing test results and maintenance guidance. Step 5: Periodic review during scheduled inspections to confirm indicators and replacement cycles.
Many plants choose to align surge improvements with a
distribution board upgrade or bundle the work into routine
industrial inspections for efficiency. Sites working on decarbonisation also review generation options using our
industrial solar project comparison tool, ensuring AC and DC surge protection is designed from the outset. The result is a cleaner power environment, better machine availability, lower repair costs, and a more sustainable operation with less waste from premature failures.
