ERITECH System 1000 Lightning Protection

Product Enquiries:

The ERITECH INTERCEPTOR SI is an Early Streamer Emission (ESE) air terminal that is designed in accordance to the NFC 17-102 standard.

The design requirements, protection level calculations, and protection radius are obtained from this standard.

ERITECH INTERCEPTOR SI includes an internal control circuit, which claims an early launch of an upward leader, as compared to other passive air terminals.

ERICO offers three (3) ERITECH® INTERCEPTOR SI air terminals.

• SI25 with a triggering advance of 25μs
• SI40 with a triggering advance of 40μs
• SI60 with a triggering advance of 60μs

During thunderstorm conditions when the lightning down-leader is approaching the ground, an upward leader may be created by any
conductive surface exposed to the intensifying electric field.

In the case of a passive conventional lightning rod, the upward leader propagates only after a long period of charge reorganization, although in the case of the ERITECH INTERCEPTOR SI ESE, the initiation time of an upward leader is greatly reduced.

The ERITECH INTERCEPTOR SI ESE terminal generates controlled magnitude and frequency pulses at the tip of the terminal during high static field characteristic prior to a lightning discharge. This enables the creation of an upward leader from the terminal that propagates towards the downward leader coming from the thundercloud much earlier than a conventional air terminal. To build a system, you will need to select
