5 Introduction Tyco Electronics has been manufacturing surge arresters for over 60 years. Our knowledge and experience we use to develop our surge arrester range today. Tyco Electronics is well known for their insulation and protection products worldwide. The range of HV surge arresters up to 550 and line discharge classes from 2 up to 5 operates in 130 countries in diverse climates from the artic circle to the tropics. Since 1988 Tyco Electronics have designed the patented series parallel metal oxide surge arrester which unique in construction and provides many advantages over conventional single column and multiple columns porcelain and polymeric housed arresters. They were designed and tested to meet defined abnormal service conditions as detailed in Annex A of IEC (1991). The unique construction of this series parallel surge arrester provides electrical and mechanical properties that cannot be obtained with single or multiple column types. In particular the geometry and unitary construction provides inherent voltage grading that does not require additional grading rings or further correction of the maximum continous operating voltage (Uc) required for arresters of conventional construction. Benefits Low residual voltages Superior protection margins Superior TOV performance Inbuilt stress grading along the full length More effective grading per unit length than a single column type Similar stress distribution like single column type, but without stress grading ring Resistant against Radial stress based on the gap free Bowthorpe patented construction Safe non-shattering short circuit behavior to higher current levels High-energy handling Direct molded housing to prevent moisture ingress Hydrophobic and tracking and erosion resistant silicone housing Superior pollution performance Excellent cantilever and tensile performance Excellent mechanical, vibration and impact withstand capability Extremely strong mechanical strength Low thermal ageing of varistor insulation Smaller footprint than equivalent single column SA with grading ring Modular design for quick installation and commission Light weight Capable to withstand seismic condition Uniform current sharing Maintenance free Tested in accordance with IEC at independent accredited laboratories Certified to GOST requirements and has accreditation in Russian Federal network and Ukraine Power Ministry Quality design and manufacturing, ISO 9001 and compliant Application This range of Silicone Rubber housed surge arresters is applicable for substation equipment and transmission lines. Because of their high cantilever strength, they n b used to replace the able support insulators n HV terminations. This results in simplified installation for HV terminations at reduced cost which is aesthetically m acceptabie to the general pubiic. It should b noted that this type of installation n not b achieved with other surge arresters of lower strength construction. 3

6 Design Concept 1-column porcelain housed and nonintegrated polymeric housed type surge arresters have a lot of weaknesses. A few of them are the control of uniform stress grading and the radial field strength which are the most important issues in these surge arrester design types. The high radial field would lead to discharge in the surge arrester enclosure between the porcelain inside and the metal oxide varistors. I. Single Modules for Series Parallel Surge Arrester B. Housing material Housing material is service proven formulation of Silicone Rubber. The silicone housing was developed using the knowledge accumulated over 35 years of internal Tyco Electronics materials science expertise and experience, resulting in an optimum shed profile and a material with excellent tracking and erosion resistance. This range of Silicone Rubber housed surge arresters has b n fully tested to meet the very severe pressure-relief tests. A. Construction The Tyco Electronics Bowthorpe patented surge arrester construction overcame this weakness by eliminating this air gap by direct moulding of the silicone rubber housing onto the wrapped ZnO varistor elements and the terminal assembly. The applied ZnO varistors ensure a very good electrical behaviour. The polymeric housing and the shed form (figure 1a) shows a good performance in salt-fog tests.

7 Voltage across this surge arrester section Thermal ageing of the varistor would be caused by the lack of self limiting under the combination of high stress and low source impedance. The series parallel surge arrester design has eliminated both, thermal and partial discharge ageing to the metal oxide arrester. The Series Parallel surge arrester has no internal air gaps and therefore requires no grading ring to avoid internal ionisation. Figure 2a shows the coaxial circuit approximation model l and figure 2b shows typical results obtained and confirmed the near uniform longitudinal voltage stress distribution. Unlike other designs the Series Parallel surge arrester does not require external means such as grading rings, to aid the voltage distribution. 3,275m radius 0.19 м (R) 0.14 м (r) 0.46 м (d) Figure 1b: Equivalent electric circuit network and the additional capacitance introduced by the series parallel surge Earth Plane 6.60 m II. The Module Series Parallel Design A. Voltage distribution and stress grading The voltage distribution is largely governed by the surge arrester geometry and intermediate plates. The intermediate connection plates of the series parallel surge arresters provide additional natural grading capacitance. The intermediate connection plates have stray capacitances which cascade and shunt to earth. Furthermore, the resistance and capacitance of the non-linear varistors also provide voltage grading. The equivalent cascade capacitance network (Fig. 1b) gives more uniform electric field distribution when compared it with a single column porcelain or nonporcelain house surge arrester with or without grading ring. Intermediate connecting plates assist the reduction in radial stress at the highest voltage sections. The overall geometry of the modular surge arrester is such that both radial and longitudinal voltage stress was at an acceptable value at the highest system operating voltage.

8 B. Thermal ageing and partial discharge An exponential longitudinal voltage grading of a surge arrester is undesirable phenomenon for varistor disks especially for those which are in top of the Surge Arrester. Low energy ionisation of the parallel air gap due to the high electrical stress would lead to ageing and failure of the varistor insulation. It has been established that partial discharge activity in close proximity to metal oxide varistors will lead to rapid ageing and premature failure. Therefore, the conventional single column arrester requires a grading ring for the additional reasons other than uneven field or thermal considerations. Equivalent circuit network (Fig. 2a) can only handle the varistor element in its linear model either before or after the threshold turn on point. For the former, varistors have high resistance and it s capacitance that dictates the surge arrester voltage grading. Beyond the turn on point the varistors have low resistance and this dominates the voltage grading. Further more for the former case, although the varistor or varistors are seeing high stress, the equivalent network as shown in figure 3, has high source impedance (Z). Under these conditions the voltage across the varistor will collapse as soon as any significant current commences to flow. The high equivalent source impedance effectively limited the voltage and current that can be applied to the varistor elements located in top surge arrestor section high stress region. It is in this context that further consideration must be given to actual ageing mechanism. Voltage across this surge arrester section C. Comparison between series parallel and single column design There are differences and similarities between the field plot to a single column porcelain house surge arrester and the Series Parallel design. They are summarized as follows: The Series Parallel arrester has more effective grading per unit length than the single column type Specially a Series Parallel 4P type exhibits similar stress distribution to the IEC example calculations, but without use the oversize diameter voltage grading rings Radial stress is an issue for porcelain housed design due to the inbuilt air gap between the varistor and the housing inner wall but not for the gap free (integrated housing) Tyco Electronics patented construction D. Series Parallel surge arrester electrical tests The following standard IEC routine testing for every series parallel surge arrester units: - Reference voltage measurement - Partial discharge measurement - Leakage current measurement - Residual voltage measurement High series impedance CURRENT (2.0 ka/div) CH 1 CH 2 CH 3 0 TIME (µs) 10 ka In addition, a proprietary internal procedure was introduced to check the current sharing of parallel columns within a series parallel surge arrester. A proprietary process ensures that between parallel columns the lowest practical differences in characteristics can be employed in one complete series parallel surge arrester. Therefore, residual voltages, energy absorption and heat dissipation are shared among the parallel units. E. Installation and maintenance advantages of the series parallel design Good stress grading without the need of oversize grading ring Light weight no heavy lifting equipment is required for installation Light weight no heavy duty foundation is required for the surge arrester Modular design - quick installation and commission Lattice structure - exceptional strong mechanical strength Non shatter of the surge arrester housing transportation easiness Non shatter of the surge arrester housing - no damage to personal and nearby expensive equipments Good pollution performancemaintenance free Environmental acceptable materialmaintenance free The series parallel design is capable to withstand seismic condition set in the current international standards which guarantees reliable maintenance in all regions.

22 Transmission Line Surge Arresters - TLA Lightning is responsible for approximately 65% of all of the non-scheduled outages occurring on transmission lines. Power supply utilities have verified the load losses due to voltage sags in their systems from transitory outages caused by lightning activity and in some regions they have found serious permanent damages on important lines. The effect of transitory disturbances on transmission lines can also be more critical in areas with high ground resistivity when associated with high lightning activity. Although a fault time is shorter than 1 minute, in many cases this is still unacceptable. This loss of supply is critical for all modern industries, electronical equipment and especially production processes. In most cases line arresters (TLA), electrically connected in parallel with the insulating string, have been considered as the most effective method currently applied to improve transmission line performance, especially when associated with improvements of the grounding system and usually presents the best benefit versus cost relationship in reducing flashovers of the insulator string due to excessive voltages.

24 Surge Counters Type SC 12 & SC 13 The Tyco Electronics Bowthorpe EMP range of Surge Arrester monitoring instruments are fully tested for use with any manufacturers surge arrester. The SC 12 is a Surge Counter only, whilst the SC 13 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 SC 12 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 high degree of resistance to surface corrosion. The glass viewing window is sealed in place, using a silicon rubber adhesive, and a desiccator is enclosed to ensure any residual moisture trapped during sealing is absorbed for the service life of the counter. Mounting is effected by means of an integrally cast lug at the rear of the case providing a single clearance hole for the galvanized steel M 12 bolt supplied. The SC 12 and SC 13 are service proven and require no special maintenance or servicing apart from general cleaning of the glass viewing window and the moulded epoxy resin line bushing.
