4 What are transient overvoltages and why do you need protection? Transient overvoltages are large, very brief and potentially destructive increases in voltage. Causes Transient overvoltages can be caused by: the secondary effects of lightning strikes (either between clouds or to ground) from a kilometre or more away the electrical switching of large inductive loads (such as motors, transformers and electrical drives), or capacitative loads (such as power factor correction) Devastating effects Although they last only thousandths or millionths of a second, transient overvoltages can devastate modern electronic systems: disrupting system operations, through data loss, data and software corruption and unexplained crashes degrading equipment components and circuitry, shortening equipment lifetime and increasing failures destroying components, circuit s and I/O cards causing costly and unnecessary system downtime Transient overvoltage damage to the circuit, left, is clear to see, but most damage is barely visible, as below. Introduction What are transient overvoltages and why do you need protection?

5 What are transient overvoltages and why do you need protection? Growing threat The miniaturisation of electronic components and circuits makes systems ever more susceptible to damage, and the growing use of electronic systems further increases our vulnerability to the effects of transients. The new BS E/IEC 6305 Protection against lightning standards therefore emphasize the need to protect electronic equipment and systems to ensure safety and business continuity. Most modern electronic systems are at risk: computers data communication networks building management systems PABX telephone exchanges CCTV equipment fire and burglar alarms telecom base stations uninterruptible power supplies (UPSs) programmable logic controllers (PCs) plant sensors telemetry and data acquisition equipment oss of these systems would cripple industrial, commercial and government organisations alike. Risk assessment Although most of us work in buildings with lightning conductors, these aren t designed to, and won t, stop transient overvoltages from damaging electronic equipment. As recognised by the latest BS E/IEC 6305 standards, to prevent lightning damage to electronic systems, this structural lightning protection needs to be complemented with transient overvoltage protection. The single risk assessment of BS E/IEC 6305 encompasses protection for both the structure and its contents - human life and electronic equipment. Interestingly, the risk of transient overvoltage damage to electronic systems inside a building is greater than the risk of damage to the building itself. Therefore, if, like most people, you work in a building where structural lightning protection has already been thought necessary, then there is a ready made argument for transient overvoltage protection. Example: collection area comparison This site consists of a main building A, auxiliary buildings B and some ground level sensors C, which are linked by various underground cables. The collection area for this site for a direct lightning strike is a distance equivalent to the height of the structures laid out in plan (shown as the shaded area). The effective collection area for transient overvoltages is much larger. It includes a collection area associated with the surrounding ground (unshaded), plus additional areas (not shown) for incoming power and phone lines D. For more information about lightning protection standards, contact Furse. Protection benefits Effective transient overvoltage protection can prevent: fire risks and electric shock hazards health and safety hazards caused by plant instability, after loss of control loss of essential services fire alarm, security systems, building management systems lost/destroyed data or equipment damage repair work especially costly for remote or unmanned installations the high cost of extended stoppages sales lost to competitors, lost production, deterioration or spoilage of work in progress 3 What are transient overvoltages and why do you need protection? Introduction

6 Classification of Surge Protection Devices International and European Standards IEC and E (replacing standards such as DI VDE 0675) determine the co-ordination of surge protectors according to their location and requirements. Type 1 (Class I/Class B) protectors ocated at an area where high lightning currents are expected. Typically fitted to provide equipotential bonding at the service entrance (main distribution ). Type (Class II/Class C) protectors ocated at sub-distribution s to control overvoltages, often residual voltages, from the upsteam Class I lightning current arrestors. Type 3 (Class III/Class D) protectors ocated close to the equipment, typically at the socket outlet, they provide local protection by limiting overvoltages caused by switching operations to safe levels. Surge protection devices must provide a level of protection below the withstand voltage of equipment to prevent equipment damage. The withstand voltage depends on the type of equipment and its sensitivity. These withstand levels are defined in 4 overvoltage categories by IEC as shown below. Using a co-ordinated set of protectors, as offered by the Furse MMP Series, optimum protection from damage to equipment is achieved. For protection of highly critical and sensitive equipment, where continual operation is necessary, please contact Furse for further information.

For more details and to see the direct comparisons across the range, please refer to the MMP Product Selector Chart on page 1. T-C etworks For systems with a combined eutral/earth supply conductor (). T-S etworks For systems with separate eutral/earth supply conductors ( & ). T-C-S etworks For systems with a combined eutral/earth supply conductor that is split locally to provide a separated eutral conductor (, & ). TT etworks For systems where only ive and eutral conductors are provided from the mains supply. An Earth for the equipment is provided locally. Surge protection between eutral/earth can be offered by a spark gap (GDT) device to provide galvanic isolation between the eutral supply and local Earth conductors.
