Mechanical and electronic strike counters recording every lightning discharge event on the down conductor — essential for maintenance scheduling, insurance documentation, and IEC 62561-6 compliance.
IEC 62305 Lightning Protection System — Compliance by Standard
Four interrelated standards governing LPS design from initial risk assessment through to component testing. A compliant installation must satisfy all four parts — not just select components.
General Principles — LPS Design Framework
Defines lightning current parameters, damage categories, and the protection level (LPL I–IV) framework. Every external lightning protection system design starts here — LPL determines the minimum Iimp for air terminals and down conductor cross-section.
View LPS product range →Risk Management — Is an LPS Required?
Quantifies annual probability of lightning damage. Determines whether a complete lightning protection system is required and at which protection level — the mandatory first step before any product selection or design work begins.
LPS risk assessment guide →External LPS — Air Terminals & Grounding
Covers external lightning protection system design: air termination methods (rolling sphere / protection angle / mesh), down conductors, earth termination, equipotential bonding, and separation distance calculations.
ESE & Franklin air terminals →Internal LPS — Type 1 SPD Coordination
Governs internal lightning protection system: SPD selection by zone, equipotential bonding, shielding, and cable routing. Mandates Type 1 SPD at service entrance when external LPS is present — coordinated with IEC 60364-5-53.
Type 1 SPD products →Complete Lightning Protection System — Find the Right Products
Four product categories — every complete lightning protection system needs all four. Select each category to find the right model for your project specification.
ESE (TPKB / TPKSE): single terminal covers large areas up to 107m radius — ideal for industrial sites, large roofs, open areas. ESE air terminals →
Franklin Rod (TPKA / TPKT / TPKBF): universally accepted IEC 62305-3 & NFPA 780 passive rod — standard for buildings, mesh arrays, NFPA projects. Franklin rods →
Solid copper (99.9% pure) or copper-bonded steel (≥254µm Cu layer · IEC 62561-2). Diameter 12–25mm, lengths 1.5m / 2.4m / 3m, custom on request. Target resistance ≤10Ω. Send your project drawing or spec sheet — we quote within 24 hours. Grounding accessories →
IEC 62305-1 requires a strike counter on every down conductor. Choose TPKG-3M (SS304, IP54, 99,999 count) for standard sites or TPKG-S (ABS, IP67, 9,999,999 count) for coastal or high-exposure environments. Both are self-powered — no battery or wiring required.
IEC 62305-4 mandates a Type 1 SPD at the service entrance whenever an external LPS is installed. A Type 1+2 combined SPD eliminates the 10m separation requirement. TrilPeak supplies the full AC and DC SPD range alongside all LPS components — one PO, one CE document set.

Frequently Asked Questions — Lightning Protection System
What is a lightning protection system (LPS) and what does it consist of?
An LPS intercepts a lightning strike, safely conducts the current to earth, and limits the resulting surge on internal electrical systems. A compliant IEC 62305 system requires four subsystems: air termination, down conductors, earth termination, and internal SPD protection. All four must be present — missing any one leaves the others ineffective.
What is the difference between ESE and Franklin lightning rods?
A Franklin rod is a passive conventional air terminal governed by IEC 62305-3 — widely specified, universally code-accepted, protection radius typically 20–60 m depending on height. An ESE (Early Streamer Emission) air terminal generates an upward leader earlier, claiming protection radius up to 107 m per NF C 17-102. ESE is not recognized by IEC 62305 or NFPA 780 as a primary protection method. Full comparison and selection guide →
What earth resistance is required for an IEC 62305 LPS?
IEC 62305-3 recommends ≤10Ω for the earth termination system. In high-resistivity soils, multiple parallel electrodes or chemical ground enhancement may be required. Solid copper rods achieve lower resistance than copper-bonded steel of the same dimensions — copper is preferred where the lowest earth resistance is specified or where permanent burial in corrosive soils is expected.
How many down conductors does IEC 62305-3 require?
Minimum 2 down conductors for any structure, spaced equally around the perimeter. For structures with perimeter >25 m, maximum spacing is 10 m (LPL I), 15 m (LPL II), or 20 m (LPL III/IV). Each conductor must connect to its own earth electrode. An inline strike counter is recommended per conductor for maintenance and compliance documentation.
Why is a Type 1 SPD mandatory when an external LPS is installed?
When an external LPS is present, a portion of the direct lightning current (10/350 µs waveform) enters the building via service entrance conductors. Only a Type 1 SPD rated by Iimp is designed for this waveform. Both IEC 60364-5-53 and IEC 62305-4 mandate a Class I SPD at the service entrance. A Type 2 SPD alone would be destroyed by the energy of a direct lightning event.
What is the purpose of a lightning strike counter?
A strike counter per IEC 62561-6 records every lightning discharge event on the down conductor. The data drives: (1) determination of when to inspect and re-test the earth termination system; (2) insurance claim documentation; (3) verification that the system is correctly intercepting strikes. Most inspection protocols recommend earth resistance testing after every 5–10 recorded strikes.
What is the required separation distance between the LPS and internal wiring?
IEC 62305-3 clause 6.3 defines separation distance s = kᵢ × kc / km × l. Failure to maintain separation causes side-flashing between the down conductor and internal metallic parts — which can ignite fires or destroy connected equipment. Where the required separation cannot be achieved physically, equipotential bonding or SPD installation at the point of parallel routing is required.
What is the difference between solid copper and copper-bonded steel grounding rods?
Solid copper rods offer the highest conductivity and lowest corrosion risk — best for permanent structures and shallow installations in corrosive soils. Copper-bonded steel rods (≥254 µm copper layer per IEC 62561-2) combine the mechanical strength for deep-driven installations with copper's corrosion resistance at lower cost — the preferred choice for rocky soils and high-volume project specifications.
Are your LPS products certified and what documentation is provided?
All TrilPeak LPS products are manufactured to IEC 62305 and IEC 62561 series standards under ISO 9001:2015 quality management. Documentation provided with every wholesale order: IEC conformity documents, material test certificates (copper purity, coating thickness), salt-spray and pull-strength test reports, product datasheets, and installation manuals. CE marking documentation available for EU market projects.
Does my building legally require a lightning protection system?
Legal requirements vary by jurisdiction, but IEC 62305-2 provides the universal risk-assessment framework used globally. Protection is required — or strongly recommended — for structures with high occupancy, critical infrastructure, explosive/flammable content, or locations with high ground flash density. For most commercial and industrial buildings, a risk assessment under IEC 62305-2 will determine the required LPL. Consult your local electrical regulations and building code for jurisdiction-specific mandates.
