The Stormaster Early Streamer Emission air terminal uses the naturally occurring electrical field to complete the timely release of an upward streamer. This process provides for a safe and efficient method of controlling dangerous lightning energy at a preferred point. As a thunder storm gathers overhead the ambient electrical field surrounding the Stormaster ESE begins to rise in voltage. Upon the approach of a downleader towards the protected area there is a rapid increase in the electric field which initiates the triggering of an upward streamer from the Stormaster ESE terminal. The concept of earlier allows for a larger or enhanced area of protection to be provided by the Stormaster ESE in comparison to a conventional rod. With the release of the upward streamer from the finial tip earlier than other competing structural points, the Stormaster ESE terminal becomes a preferred point for the capture of the lightning discharge within the protected area.

The Stormaster ESE range of terminals provides a safe and efficient system for the protection of your facility from direct lightning strikes. The LPI Stormaster ESE terminal captures the lightning energy at a preferred point.
The non-radioactive terminal conveys the energy to ground via down-conductor(s). When the energy enters the dedicated lightning earth, it is safely dissipated without risk to personnel and equipment.

LPI Product Offering
Lightning Protection International Pty Ltd offers a comprehensive range of products and services as part of its complete solution to your lightning problems. These products cover Direct strike protection, surge and transient protection and earthing solutions.
