2 22 LPI Guardian System 5 Key Benefits Blunt finial tip which minimizes corona effect. 4 electrically isolated panels. High Voltage connection at the base. Triggering procedure allows the initiation of an intercepting streamer. Product Description LPI offers a family of air terminals and accessories. Our product design is based on the most recent advances in lightning research whilst maintaining proven principles associated with the successes of the past. LPI Guardian System 5 provides a purpose-designed package for direct lightning protection. The Guardian System 5 has been tested in compliance to IEC Test Standard: IEC 60-1: A Family of LPI CAT (Controlled Advanced Triggering) series air terminals. 2. A Fibreglass Reinforced Plastic (FRP) mast. 3. A purpose-designed High Voltage Shielded Cable (HVSC). 4. A lightning strike recorder (LSR). 5. An earthing system which consists of Earth rods, Clamps, Copper tapes and Ground resistance improvement powder (GRIP). CAT Principles 1. A Guardian CAT terminal consists of a grounded blunt lightning rod surrounded by an electrically floating medium. Rounded or blunt tips have proven to be more efficient than sharp points by producing minimal corona effect. This has been clearly proven in tests conducted at South Baldy Peak in the Magdalena Mountains of central New Mexico, USA. (Source: The Measurement of Lightning Rod Responses to Nearby Strikes by C.B. Moore, G.D. Aulich, and W. Rison/ May 2001) 2. During the static thunderstorm phase when the electric fields are steady at around 5-15 kv/m and even in the very early stages of leader approach, the medium presents as a relatively low field intensification surface due to the blunt configuration of the finial tip. This restricts the production of corona or point discharge ions and is critical because excessive production of ions (corona) results in a space charge cloud above the air terminal which masks the electric field at the tip of the terminal when the leader eventually approaches within range. 3. The Guardian CAT terminal is comprised of four separate electrically isolated panels arranged to allow the section facing the step leader to rise in voltage due to a capacitive coupling effect. Because the CAT terminal is essentially isolated from the ground potential, the electric field increases as the discharge approaches closer to the panel facing the step leader. It then experiences repeated pulsing until this section (panel) rises in voltage to the point when a triggering arc is generated at precisely the right time, which in turn initiates the streamer, which connects with the approaching down leader. 4. This triggering arc creates two key effects. First it produces a large number of ions which are needed to initiate an upward leader. Secondly it causes a large snap change in the electric field immediately above the air terminal which provides the necessary kick for the inception of an early, stable, propagating upward leader. The initiation of such advanced triggering results in the approaching leader being intercepted earlier, which ensures a larger protective area around the Guardian CAT terminal.

3 3 CATCALC Software Design LPI uses a CAD based software design program CATCALC to customize a cost effective and safe lightning protection solution for any structure. The CATCALC program considers factors such as thunder days per year, height above sea level, level of protection desired/recommended (Standard - High - Very High), Physical dimensions of the structure and building materials used. Competing features (which have the ability to create streamer development) are taken into consideration during the design process. A customized CATCALC design will provide to the end customer a design report encompassing elevation, plan and side views of the proposed lightning protection installation along with a detailed bill of materials for all required accessories. Risk Assessment In accordance with Australian Standard (AS1768) all CATCALC designs are subjected to a site risk assessment to determine the perceived risk from a lightning strike. The risk assessment considers the following. Usage and contents of the structure(s) Construction materials of the structure(s) Height of the structure(s) Situation at site - Flat ground or elevated above sea level Average thunder days per annum LPI Product Range SECTION PAGE LPI PRODUCTS A 9, 10 LPI GUARDIAN TM TERMINAL B 11 LPI UPPER TERMINATION KIT C 11 LPI FRP SUPPORT MAST D 12 LPI INLINE COUPLING E 12 LPI GUY KIT F 13 LPI GUY RING G 13 LPI LOWER MAST ASSEMBLY H 13 LPI SADDLES FOR CANTILEVERING MAST I 14 LPI U-BOLT J 14 LPI HIGH VOLTAGE SHIELDED CABLE K 14 LPI CABLE TIES L 15 LPI SADDLES AND FIXINGS M 15 LPI BEAM CLAMP AND CABLE SUPPORT N 15 LPI LIGHTNING STRIKE RECORDER O 16 LPI LOWER TERMINATION KIT P 16, 17 LPI EARTHING SYSTEM Q 17 LPI INSPECTION PIT R 18 LPI GROUND RESISTANCE IMPROVEMENT POWDER Commercial in Confidence Document: 36 TD Guardian.pub Version: /12/2008 Copyright 2008 LPI 3
