Functions

Lightning impulse counting – records lightning discharges or strong impulses passing through the lightning protection system.
Mechanical counter – allows the number of recorded impulses to be clearly viewed without additional equipment.
Counting range 0–99999 – can store a large number of impulses, making it suitable for long-term maintenance of a lightning protection system.
Impulse detection from 3 kA – records lightning discharges and stronger impulse overvoltages from the specified current threshold.
Maximum detectable impulse current up to 100 kA – designed to register strong lightning current impulses.
Operation without power supply – no batteries, wired power supply or additional electrical connection required.
Visual control of the lightning protection system – after a storm, it is possible to quickly check whether the system was affected by a lightning discharge.
Reset function – the counter can be reset if this is provided in the specific model version.
Installation on the down conductor – mounted on the lightning protection down conductor to record impulses passing through the system.
Suitable for outdoor conditions – designed for outdoor use where the device is exposed to moisture, temperature fluctuations and atmospheric conditions.
Durable metal housing – protects the internal mechanism from mechanical impact and environmental factors.

Use

For household users: suitable for private houses, homesteads, garages or utility buildings with an installed lightning protection system. The counter allows the user to check after a storm whether the lightning rod was affected by a lightning discharge.

For electricians: used when installing or maintaining lightning rods, grounding systems and surge protection systems. Helps to quickly assess whether an additional system inspection is required after a storm.

For engineers / designers: relevant when designing lightning protection systems for industrial, commercial, energy or solar power plant facilities where lightning impulse recording and system monitoring are required.

For maintenance specialists: useful for regular inspection of lightning protection systems in buildings, towers, antennas, solar power plants or industrial facilities. If the counter reading has changed, inspection of grounding, connections and surge protection can be planned.

For industrial and commercial facilities: suitable for factories, warehouses, office buildings, communication towers, power plants and other facilities where it is important to know whether the lightning protection system has been activated.

Advantages

Operates without a power source – no batteries, 230 V power supply or additional electrical connection required.
Mechanical counter – simple and clear reading of indications.
Records up to 99999 impulses – large counter capacity for long-term use.
Detects impulses from 3 kA – suitable for recording lightning discharges.
Maximum detectable impulse up to 100 kA – suitable for strong lightning impulses.
Suitable for outdoor conditions – operates in atmospheric conditions from -20 °C to +65 °C.

Disadvantages

Not intended as a standalone lightning protection device – it only counts impulses and does not itself divert lightning or protect equipment from overvoltages.
The installation location must be selected correctly – an incorrectly installed counter may fail to record impulses or may show inaccurate data.
No remote monitoring function – this is a mechanical counter, so the readings must be checked visually.

FAQ

What is a lightning discharge counter used for?
It is used to count lightning discharges or strong impulses passing through a lightning protection system. This helps to determine whether the lightning rod or lightning protection system has been affected by lightning.

Does the counter require power supply?
No, this model does not require an additional power source.

Where is this counter installed?
It is installed on the down conductor of the lightning protection system so that it can record lightning impulses passing through the system. The exact installation location must be selected according to the lightning protection project and the manufacturer’s instructions.

Is this counter suitable for outdoor use?
Yes, the device is specified as suitable for outdoor use. It operates within a temperature range from -20 °C to +65 °C.
