The design of your lightning protection system is an important part of your installation. A system designed correctly by our engineers allows us to identify what is required to install your system in-line with the current standards and specification set out in BS EN 62305 – 2006.
A correctly installed lightning protection system performs the simple, yet invaluable task of providing a network of low resistance paths for lightning current to follow in preference to other parts of a structure. While the concept behind lightning protection is relatively simple, the requirements for proper installation are specific and often complex.
Whether it be a Domestic, Commercial or Historic building our systems are designed and installed to the highest standards and comply with the current standards and specification set out in BS EN 62305 – 2006. A lightning protection installation can range from a Class I, II, III & IV and in brief consists of an Air-terminal Network, Down Conductors and Earth Terminations.
Here at Tristan G Murless Electrical Contractors, we offer a comprehensive service, which includes lightning protection testing and certification. Section 5 of Electricity at Work Act 1989 states that all lightning conductors should be visually inspected and tested at regularly fixed intervals, Our lightning protection testing service adheres to current industry standards and specifications laid out in BS EN 62305.
Lightning protection testing involves us carrying out a visual survey of the conductor system, and electrical resistance testing of the conductor’s continuity and resistance to earth.
Following this we will compile a detailed report of all relevant findings. This includes photographic evidence and costing for any maintenance or remedial work that may be necessary. Upon completion of a satisfactory inspection a certificate of compliance will be issued.
Power surges or transient over voltages 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:
Tristan G Murless can supply and install effective protection from lightning surges and over voltages using components supplied by leading surge protection manufacturers designed specifically for:
We can provide a ‘free of charge’ site survey for our customers together with a supply only service which offers significant discounts from the UK’s main transient/surge suppliers.
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
