Обзор

Type 1 lightning arresters include the system cables in the equipotential bonding, which protect the low-voltage systems against the overvoltages and high surge currents that can be triggered by direct or indirect lightning strikes.

The protection level is lowered to 1.5 kV by the lightning arresters, which reduces the load on the plant if a lightning strike is discharged.

The lightning arresters are enclosed and are suitable for installation in the precounter area.

All spark gaps are tripped. For this reason, decoupling reactors are no longer required for the installation of overvoltage protection devices.

The lightning arresters are tested by wave-shaped lightning impulse currents 25 ... 100 kA with waveform 10/350 μs.

Особенности

• The rated arrester voltage is a uniform 350 V AC. This increases safety in systems with extended voltage overshoots.
• All lightning arresters are fitted with a mechanical fault indication, which does not require an extra power supply. This means they can be installed in the precounter area, where electrical plants can be protected particularly effectively.
• The protective modules are plug-in versions. No dismantling of electrical wires required when replacing the protective modules. When taking insulation measurements, the protective modules are simply removed in order to disconnect from the power supply.
• All lightning arresters have a remote signaling contact, which signals if the device fails.
