3 Surge Arresters Tyco Electronics Energy Division covers a wide range of porcelain and polymeric transmission surge arresters. The Bowthorpe EMP range of arresters has demonstrated reliable performance in environments all over the world for over 60 years. Bowthorpe EMP, unlike other manufacturers, recognise that some Power Utilities require the need to maintain the conventional ZnO porcelain surge arrester. A program of continuous design update and development on the porcelain arrester has provided a range of surge arresters to meet the demands of most system voltages. Design Evaluated and Type Tested at the HV Laboratory in Brighton. Bowthorpe EMP were the first manufacturer to develop the polymeric housed arrester for commercial operation (1983). Range of HV surge arresters in service under the severest climatic conditions up to 550kV system.

4 H, 2H & 3H Modular Single Column Polymeric Surge Arresters The essential feature of the international construction is the homogeneous resin and glass fibre bond over the complete insulated surface of the ZnO varistor elements. The arrester module has good conductivity even when high cantilever loads are applied and provides a uniform dielectric at the insulated surface of the ZnO elements. No air gap therefore no internal ionisation Light weight compared to porcelain Ease of installation Non shattering housing Vandal proof Electrical Performance Specification: IEC Classification: 10kA Voltage Rating: 3kV to 132kV High Current Performance: 100kA Line Discharge Class: 2 Energy Capability: 4.5kJ/kV at Ur according to IEC (Clause table 5 and 8.5.5) HSR Rated Voltage to 48kV 2HSR Rated Voltage to 84kV 3HSR Rated Voltage to 126kV Insulation Material: Silicone Rubber 110kV Surge Arresters - Estonia Typical Applications ARC Furnace Transformers TLA Transmission Line Arresters Cable Terminations Substations Extended Creepage HSREP45 Surge Arrester 66kV Surge Arresters - Statkraft, Norway 4

8 Series Parallel Modular Polymeric Surge Arresters The series parallel construction comprises individual surge arrester modules rated between 30 and 45kV interconnected by means of corona free aluminium alloy cross arm. Each surge arrester module is completely impervious to the ingress of moisture and utilises the high mechanical strength properties of the ZnO varistors bonded by cured resin impregnated glass fibre. The seismic performance of the 500kV arrester has been proven in two leading test facilities. Bonneville Power USA performed at Portland State University and NEL East Kilbride UK. No air gap therefore no internal ionisation Light weight compared to porcelain Ease of installation Non shattering housing Vandal proof Tolerance to seismic disturbances Patented glass fibre core design gives high mechanical strength and void free construction Optimised voltage stress grading eliminates need to oversize stress grading ring, therefore the compact series parallel can be installed in tight spaces without infringing electrical or surge safety clearances. The diameter of the series parallel design has been calculated to reduce the radial field stress to a minimum, even under adverse environmental conditions.

16 Station Class Porcelain Surge Arresters Porcelain surge arresters are available for applications up to 400kV systems. Porcelain housing designs have been used by us for over 55 years. From 1945 we produced porcelain surge arresters to the gapped silicone carbide pattern and since 1980 we have produced arresters to the gapless ZnO design. The design consists of porcelain housing which conforms to IEC-815 with an Aero Dynamic shed profile. The varistors, spacers and locating rings are assembled under compression with pressure relief diaphragms at either end. The air void is evacuated and replaced with dry air, then sealed. Routine tests are carried out to show that the manufacturing conforms to the current International standard.

32 There are few places more exposed to direct lightning strikes than an airfield. In such situations lightning strikes within the vicinity of the airfield can result in permanent damage to electrical equipment. Airfield lighting circuits are particularly vulnerable as the associated cable networks present an attractive low impedance path for lightning surge currents to earth. The result of a nearby lightning strike can be permanent damage to the control circuits unless a suitable lightning arrester is fitted to the lighting control equipment. The Lightning Arrester Type 2DCAFL4 is designed to protect airfield lighting control equipment from the effects of direct or indirect lightning strikes. The arrester is provided with two metal oxide active elements which are connected in parallel with the supply cables. Installation requires only the cutting of the supply cables at a convenient place close to the control equipment and connection of the arrester to a good electrical earth. Arrester 2DCAFL4 can be fitted to new equipment but is primarily designed to be quickly installed on existing circuits. The SPG1 Spark Gap is designed for use with traction circuits to provide virtually instantaneous protection of both equipment and personnel from power system faults. The unit also provides protection against lightning generated voltages which would otherwise cause damage to signalling and cable circuits. The SPG1 is constructed in stainless steel of rugged design allowing the SPG to be installed in harsh environments such as track side locations without additional weather protection. Suitable for use on circuits where standing/induced voltages do not exceed 110v RMS. Fast operation Typical 5 microseconds with 11kA fault current. Internal spark gap module unit easily replaced after fault current operation. Fail safe feature ensures safety to personnel and equipment. Service proven performance. High internal impedance with low capacitance does not interfere with track signalling circuits. The Bowthorpe EMP range of Surge Arrester monitoring instruments are fully tested for use with any manufacturers surge arrester. The SC12 is a Surge Counter only, whilst the SC13 provides the additional measurement of total leakage current. The analogue instrument provides a means of monitoring the current through the arrester and the leakage current over the surface of the arrester housing. Significant changes after installation may indicate a deterioration in the arrester or a build up of surface contamination. These instruments, which require no auxiliary supply, are designed for installation in the earth connections of a single surge arrester or alternatively the SC12 may be used with the common earth of a three phase set. Fully weatherproofed and sealed for life they are housed in a one piece gravity die cast aluminium case coated to enhance its already rear of the case providing a single high degree of resistance to surface clearance hole for the galvanised corrosion. The glass viewing window steel M12 bolt supplied. is sealed in place, using a silicon rubber adhesive, and a desiccator is The SC12 and SC13 are service enclosed to ensure any residual proven and require no special moisture trapped during sealing is maintenance or servicing apart from absorbed for the service life of the general cleaning of the glass counter. Mounting is effected by viewing window and the moulded means of an integrally cast lug at the epoxy resin line terminal bushing.
