Surge Protection: Electronic Systems Protection
I.S. EN 62305 (part 4) requires that surge protection must be included as part of a lightning protection system, to safeguard the building, and the people and equipment within it, from the damaging effects of transient over-voltages.
Surge Protection has become an important part of lightning protection, previously if a building had lightning protection it was assumed that it would be protected. There is evidence that a large part of lightning damage is caused by surge through the electrical system or indeed metallic services be it gas, water or television. Surge devices can now be included in the lightning risk assessment and can be tailored to suit all buildings. This allows protection to the devices that used to be damaged by a lightning strike nearby and indeed reduces the risk of physical damage and risk of death.
We can apply the I.S. EN 62305 to existing buildings by risk analysis and make precise recommendations as to what is required to achieve the latest standards. The risk assessment also allows us to confirm if the current lightning protection is valid and satisfactory. This allows many of our clients to approach lightning protection on a modular level, where lightning protection is in place, we can advise which area is at most risk and prepare a schedule allowing the areas at highest risk to be rectified first. This is becoming increasingly insurance driven and our calculations can be used to demonstrate how the lightning protection is satisfactory and achieves the required standard.
We have used the risk analysis software to improve lightning protection where buildings have changed use and the risk has changed. This is especially useful where the risk is increased by age or a change in the number of hours a building is occupied.
For outstanding protection against transient over-voltages, Powercom Solutions can supply all of your surge protection requirements, sourced directly from Phoenix Contact. SPDs provide a cost-effective and best-engineered solution to ensure compliance with I.S. EN 62305. Being virtually maintenance-free, and with repeated protection built-in as standard, SPDs from Powercom Solutions offer the best means of achieving long-lasting, cost-effective protection against transient over-voltages.
Power surges or transient overvoltages can be caused in two ways: either as the secondary effect of a lightning strike (up to a kilometre away), or by the electrical switching of large inductive loads (such as motors and transformers). They may last less than a fraction of a second but they are powerful and potentially highly destructive causing:
Disruption to system operations
Degradation of equipment components
Destroying components and circuit boards
Causing costly and unnecessary downtime
Powercom Solutions can supply and install effective protection from lightning surges and overvoltages using components supplied by leading surge protection manufacturer ‘Phoenix Contact’ designed specifically for:
Mains power supplies
Data and telecoms equipment
RF, CCTV, rail and CATV systems
Additionally, we offer an installation service which can include ‘out of hours’ working to meet our customers’ requirements during those all too infrequent ‘shut-down’ maintenance periods.
We at Powercom Solutions can provide a ‘free of charge’ site survey for our customers together with a supply only service which offers significant discounts from the world’s main transient/surge supplier. Phoenix Contact is a globally present market leader with its corporate headquarters in Germany. The wide variety of our innovative products makes it easy for our customers to find future-oriented solutions for different applications and industries. This is especially true for the fields of energy, infrastructure, process and factory automation.
Independently verified quality (KEMA Laboratories): Phoenix Contact has a large part of its surge protection product range certified by independent testing institutes. By doing so, compliance with standards and maximum product quality are verified for the user. These certification marks from independent testing institutes confirm, for example, that the current version of the respective testing requirements from the IEC 61643 standard series has been fulfilled.
All Phoenix Contact SPDs with Safe Energy Control Technology are extremely powerful and particularly durable. However, should the status indicator signal the need for replacement within the first five following the purchase, a replacement plug will be provided for free by Phoenix Contact and Powercom Solutions. Meaning all SEC products showing a red status will be replaced for free.
