Industrial facilities

Your power is connected. Is your protection?

The problemLightning protection with one specialist, earthing with another, surge protection in a separate package. The risk crosses those boundaries and nobody owns the gap.

Every facility depends on an electrical system that must work as a whole, yet its protection is often divided between specialists. LPES brings Lightning Protection, Power Protection, Earthing Protection and Surge Protection together under one engineering responsibility. We call it Lightning to Load.

  • Lightning protection systems built to IEC 62305-3 and IS/IEC 62561
  • Earthing and bonding to IS 3043:2026, IEEE 80 and CEA Regulations 2023
  • Surge protective devices for power, SCADA, PLC, data and signal lines to IEC 61643-11 and IEC 61643-21

The issue

When protection is divided, no one owns the gaps

Electrical risks cross those boundaries. Responsibility should connect them. Four reasons the gaps matter.

4packages, no owner of the gaps

Protection is bought in separate packages

Lightning protection goes to one specialist, the power study to another, earthing to the civil contractor and surge protection to the panel builder. Each package can pass its own inspection while the connections between them are left to chance: the down conductor that never reaches the earth ring, the SPD with no short path to the earthing bar.

What LPES does about it

One engineering responsibility across all four pillars, with every interface drawn, owned and tested.

Where risk moves

Thirteen points where one plant is exposed

Lightning, surges and earth faults move through the whole installation. One working plant in 3D, turning slowly. First the red pulses show how lightning, surge and fault current travel through it. Then the view switches to the LPES system: air termination, SPDs on power and data lines, bonding, step and touch protection and a verified earth fault loop. Select any numbered point.

Roof and rooftop equipment

The problem
The roof is the first thing a strike meets. Without air termination the current enters through rooftop units, vents and cable trays.
What LPES does
A mesh and rod air-termination system sized by the rolling sphere method, with down conductors at the spacing IEC 62305-3 requires.

The four pillars

Four pillars. Connected protection. Clear accountability.

One building, from the roof to the last load, in eight steps that play on their own. Use the arrows or the tabs to move through them. Each part is shown in 3D, first as the fault arrives without protection and then with the LPES system in place. Every step shows what happens to people, to assets and to operations.

Standards set the minimum. LPES designs the interfaces between them: IEC 62305 · IEC 62561 · IEC 61643 · IEC 60364 · IEC 61000-5-2 · IEC 61936-1 · IEEE 80 · IEEE 1584 · IS 3043 · IS 732 · NBC 2016 · CEA Regulations 2023

01Air termination

Drag to look around

01Lightning · Air termination

The strike is intercepted on the roof

Lightning attaches to the highest conductive point. The air-termination system makes sure that point is a conductor you chose: rods at the corners and edges, a mesh across the roof, and taller rods beside rooftop equipment so that chillers and vents sit inside the protected volume.

02Lightning · Down conductors

The current is carried down the outside

Several down conductors share the lightning current and take it to earth by the shortest, straightest route. More paths mean less current in each one and a smaller voltage across the building. Each conductor has a test joint so the earth electrode can be measured on its own.

03Earthing · Earth termination

The current is spread into the ground

Below ground a ring conductor runs around the building and joins every down conductor. Earth rods at each corner take the current deeper, and enhancing compound keeps the resistance stable through the dry season. Joints are exothermically welded because a buried clamp cannot be inspected.

04Earthing · Equipotential bonding

Everything metal is held at one potential

Inside the building the danger is a voltage difference between two things a person or a circuit can touch at once. The main earthing bar ties the earth ring to the structural steel, pipes, cable trays and the protective earthing conductor of every feeder, so they all rise and fall together.

05Surge · Electromagnetic shielding

The building is made into a bonded cage

A strike drives a magnetic field through the whole building. Every loop of cable inside it becomes a source of induced voltage, even when no current enters on the cables. An LPS alone does not screen that field. The reinforcement, metal roof and façade are bonded into a grid-like spatial shield, cables are routed together in bonded trays so the loops stay small, and the control room sits in the innermost protection zone.

06Surge · Surge protection

The surge is stopped at each boundary

Part of the lightning current always enters on the power and data cables. Surge protective devices are placed where a cable crosses from one protection zone into the next: Type 1+2 at the main LT panel, Type 2 at each distribution board, and Type 3 at the equipment. Data and signal SPDs do the same job on SCADA, PLC, RS-485, Ethernet, 4–20 mA and coaxial lines.

07Power · Power system

The supply side is studied, not assumed

The transformer, the incoming cable and the main panel decide how much fault current the earthing has to carry and how much energy an arc can release. LPES calculates both, then checks that conductors, protection settings and neutral earthing match.

08Assure · Monitoring and records

The system proves it is still working

A protection system is only as good as its last inspection. A strike counter on the down conductor logs every event, SPD status contacts report a failed module, and the test joints let each earth electrode be measured every year. The readings go into the LPES Protection Passport.

Power, data and signal lines

Every cable that enters is a path for a surge

Power is one of them. SCADA, PLC, instrument, network, CCTV and antenna cables are the others. LPES coordinates surge protective devices across power, data, signal, control and RF lines, and bonds each one to the same earthing system.
