Functions

Lightning discharge counting – records activations of the lightning protection system and allows users to see how many times a lightning impulse has passed through the system.
Mechanical impulse counter – readings are visible directly on the device; no additional software or external display is required.
High counting capacity – the counter can count up to 999999 impulses, making it suitable for long-term monitoring of a lightning protection system.
Detection of impulses with different intensity – records impulses from 3 kA to 100 kA, therefore it can be used in various lightning protection systems.
Operates without a power supply – no batteries, mains power or additional power cable are required.
Suitable for outdoor conditions – the device is designed to operate within a temperature range from -20 °C to +65 °C.
Durable ABS housing – compact and resistant construction helps protect the counter from environmental impact.
Simple installation – mounted on the down conductor using a stainless steel clamp.
Lightning protection condition monitoring – helps determine whether the lightning protection system, earthing system or surge protection devices need to be inspected after a lightning discharge.

Use

For household users: Suitable for private houses, homesteads, farm buildings or cottages equipped with a lightning protection system. The counter allows the owner to see whether the lightning rod has been affected by a lightning discharge. After a recorded activation, a specialist can be contacted for system inspection.

For electricians: Useful for installing and maintaining lightning protection systems. The counter allows the activation history of the system to be shown to the customer and helps plan maintenance.

For engineers / designers: Relevant when designing lightning protection solutions for sites where discharge registration is required. Suitable for industrial, energy, communication, solar power plant and commercial building projects.

For industrial companies: Suitable for factories, logistics centres, warehouses, production lines and other locations where a lightning discharge may affect electrical equipment, automation systems, controllers, server rooms or communication systems.

For solar power plants: Can be used in lightning protection systems of solar power plants to monitor whether structures, module zones or the earthing system have been affected by a lightning impulse.

For maintenance specialists: Helps quickly assess whether a site has been affected by lightning. This is useful during periodic inspections of lightning protection systems, earthing, SPD surge protection devices and electrical installations.
