Amendment 1 of BS 7671, effective from 1st January 2012, requires all electrical system designs and installations to be assessed against risk of transient overvoltages of atmospheric origin, or from switching events, in line with its Sections 443 & 534. Section 443 defines the criteria for risk assessment, whereas Section 534 describes the selection and installation of suitable Surge Protective Devices (SPDs), where required, for effective transient overvoltage protection. Why is transient overvoltage protection so important? Transient overvoltages are short duration surges in voltage between two or more conductors (L-PE, L-N or N-PE), which can reach up to 6 kV on 230 Vac power lines, and generally result from: Outright damage to sensitive electronic systems, such as computers etc, occurs when transient overvoltages between L-PE or N-PE exceed the withstand voltage of the electrical equipment (i.e. above 1.5 kV for Category I equipment to BS 7671 Tables 44.3 & 44.4). Atmospheric origin (lightning activity) through resistive (see Figure 1) or inductive coupling and/or Electrical switching of inductive loads. Equipment damage leads to unexpected failures and expensive downtime, or risk of fire/electric shock due to flashover, if insulation breaks down. Transient overvoltages significantly damage and degrade electronic systems. Figure 1: Resistive coupling Figure 2: Equipment risk DAMAGE DAMAGE Degradation > 1.5DAMAGE kV (L-PE/N-PE) Safe Operating Area Degradation Degradation Safe Operating A > 2x peak operating voltage (e.g. 715 V L-N) Safe Operating Area Degradation DAMAGE Nominal system voltage Degradation (e.g. 230 V) DAMAGE Protect additional metallic services For protection measures against direct lightning strikes, and against transient overvoltages on additional metallic service lines (e.g. data, signal & telecoms), BS 7671 refers to BS EN 62305 (534.1 NOTE 2). Full protection of electronic systems can only be achieved if all incoming/outgoing metallic services, including data, signal and telecoms lines are protected. Data/ Telecom Power IMPORTANT: Equipment is ONLY protected against transient overvoltages if all incoming / outgoing mains and data lines have protection fitted.

BS 7671 Section 443 states that‚ transient overvoltages transmitted by the supply distribution system are not significantly attenuated downstream in most installations (443.1.1 NOTE 3). The illustration demonstrates how effective protection comprises a service entrance SPD to divert high energy lightning currents to earth, followed by downstream SPDs at appropriate points to protect sensitive and critical equipment. BS 7671 Section 534 therefore recommends that SPDs are installed at key locations in the electrical system: Selecting appropriate SPDs SPDs are classified by Type within BS 7671 (534.2.1), following the criteria established in BS EN/IEC 62305. –– As close as practicable to the origin of the installation (usually in the main distribution board after the meter) (534.2.1) Where a building includes a structural LPS, or connected overhead metallic services at risk from a direct lightning strike, equipotential bonding SPDs (Type 1 or Combined Type 1+2) must be installed at the service entrance, to remove risk of flashover (534.2.3.4.2). –– As close as practicable to sensitive equipment (sub-distribution level), and local to critical equipment (534.2.1) Figure 3 shows a typical installation on a 230/400 V TN-C-S/ TN-S system using Furse SPDs, to meet the requirements of BS 7671. Installation of Type 1 SPDs alone however does not provide protection to electronic systems (534.2.1 NOTE 3).

Combined Type 2+3 performance of the SPD installed at sub-distribution protects downstream sensitive equipment against transient overvoltages. Plug-in ESP MC with Type 3 performance protects critical equipment at local level against switching transients. Enhanced Total Solution Lightning Protection Zone (LPZ) Concept The Lightning Protection Zone (LPZ) concept was introduced in BS EN 62305, particularly to assist in determining the Surge Protection Measures (SPM) required within a structure. The general principle is that the equipment requiring protection should be located in an LPZ whose electromagnetic characteristics are compatible with the equipment stress withstand or immunity capability. In general, the higher the number of the zone (LPZ 2; LPZ 3 etc) the lower the electromagnetic effects expected. Typically, any sensitive electronic equipment should be located in higher numbered LPZs and be protected by its relevant SPM.

Therefore, for maximum transient overvoltage protection the SPDs connecting conductors must be kept as short as possible. BS 7671 Clause 534.2.9 defines that for SPDs installed in parallel (shunt), the total lead length between line conductors, protective conductor and SPD preferably should not exceed 0.5 m and never exceed 1 m. Current loops should be avoided. Best practice Poor installation can significantly reduce effectiveness of SPDs. Therefore, keeping connecting leads as short as possible is vital to maximize performance, and minimize additive inductive voltages. Best practice cabling techniques, such as binding together connecting leads over as much of their length as possible, using cable ties or spiral wrap, is highly effective in cancelling inductance. The combination of an SPD with low voltage protection level (Up), and short, tightly bound connecting leads will lead to an optimum controlled installation meeting the requirements of BS 7671. For SPDs installed in-line (series), the lead length between the protective conductor and SPD preferably should not exceed 0.5 m and never exceed 1 m.

These cross-sectional area values are based on the surge current that these SPD connecting leads need to handle, not the supply current. Selection of the appropriate OCPD in-line with the SPD must ensure sufficient discrimination with the upstream OCPD of the main supply load. Installers should refer to OCPD manufacturers’ operating characteristics to ensure discrimination, particularly where an installation includes a mixture of types of OCPD. However, in the event of a short circuit, for example due to the end of life condition of the SPD, the connecting leads to the SPD would need to be protected by a suitable Overcurrent Protective Device (OCPD). Therefore an SPD needs to be protected against short circuits through the use of an appropriate OCPD capable of eliminating the short-circuit. In effect, the SPD should have a dedicated OCPD installed in-line on its connecting leads, ensuring that this OCPD to the SPD discriminates with the upstream OCPD of the main supply. However, as a general rule of thumb, the OCPD for the SPD should be rated at approximately half the value of the upstream supply OCPD.
