Introduction Tyco Electronics Bowthorpe has been manufacturing surge arresters for over 60 years. Our knowledge and experience we use to develop our surge arrester range today. Tyco Electronics Bowthorpe is well known for their insulation and protection products worldwide. The range of HV surge arresters up to 550 kV 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 Bowthorpe 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 60099-4 (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. Application This range of Silicone Rubber housed surge arresters is applicable for substation equipment and transmission lines. Because of their high cantilever strength, they саn bе used to replace the сable support insulators оn HV terminations. This results in simplified installation for HV terminations at reduced cost which is aesthetically mоге acceptabIe to the general pubIic. It should bе noted that this type of installation саn not bе achieved with other surge arresters of lower strength construction.

Design Concept The patented series parallel polymeric metal oxide surge arrester is unique in construction and provides many advantages over conventional single column porcelain and polymeric housed designs. 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 The 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 shows a good performance in salt-fog tests (figure 1a).

The range of Silicone Rubber housed surge arresters has been fully tested to meet the very severe pressure-relief tests.

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 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 (figure 1b) gives more uniform electric field distribution when compared it with a single column porcelain or non-porcelain house surge arrester with or without grading ring. 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. Thus the intermediate connection plates of the series parallel surge arresters are constructed to assist the reduction in radial stress at the highest voltage sections and provide additional natural grading capacitance.

Figure 2a: Field plot of series Figure 2b: Filed plot result of series parallel Surge arrester using a coaxial surge arrester Circuit approximation model A – Varistor non-conduct B – Varistor partially conduct C – Varistor fully conduct Figure 2a shows the model 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. After confirmation the basic dimensional requirements of the modular design, attention is also turned to materials and manufacturing techniques. 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 a 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. Based on the laboratory tests and service experience, the series parallel surge arrester design has eliminated both thermal and partial discharge ageing to the metal oxide arrester. It has been established that partial discharge activity in close proximity to metal oxide varistors will lead to rapid ageing and premature failure. The equivalent circuit network of Series Parallel surge arrester (Fig. 1b) 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 the capacitance that dictates the surge arrester voltage grading. Beyond the turn on point the varistors resistance and this dominates the voltage grading. Furthermore for the former case, although the varistor or varistors are seeing high stress the equivalent circuit network, as shown in Figure 3, has a high source impedance. Under these conditions the voltage across the varistor will collapse as soon as any significant current commences to flow. The high series impedance effectively limited the voltage and current that can be applied to the varistor elements located in the top surge arrester section high stress region. Based on a high series impedance for each surge arrester section the thermal increase in a series parallel surge arrester will be reduced to a minimum.

6

Thermal ageing of the varistor would be caused by the lack of self limiting under the combination of high voltage stress and low source impedance. Therefore, the conventional single column arrester requires a grading ring for the additional reasons other than uneven field or thermal considerations. In contrast the Series Parallel surge arrester has no internal air gaps and therefore requires no grading ring to avoid internal ionisation.

Figure 3: Voltage across a surge section and it’s Thévénin equivalent circuit network C. Comparison between series parallel and single column design There are differences and similarities between the field plot to a single 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 a but not for the gap free (integrated housing) Bowthorpe patented construction D. Electrical Tests for Series Parallel Surge Arrester The following standard IEC routine testing will be done for every series parallel surge arrester: - Reference voltage measurement - Partial discharge measurement - Leakage current measurement - Residual voltage measurement 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. F.

Transmission Line Surge Arresters - TLA

Generic Technical data Specification IEC 600099-4 Classification 10 kA Voltage Rating 10 to 192 kV High Current Performance 100 kA Line Discharge Class 2 Minimum Energy Capability acc. to IEC 60099-4 at Ur 4,5 kJ/kV Disconnect Device tested in accordance with IEC 60099-4 Insulation Material Silicone Rubber Vibration Tested Report No. BOE002000 Features & Benefits • HV arrester suspended from a

transmission line giving enhanced transmission line performance Increasing system line voltage on standard insulated transmission lines

• Minimising circuit beaker operation with possible system outage resulting from back flachover on the transmission line

• Switching overvoltages are absorbed over the length of the line reducing the severity of surge at the substation

• Transmission systems can be operated even where sub-oil gives poor tower footing resistance

• Eliminating interrupted power supply for sensitive industrial processes

• Installing TLA on a standard 3 phase voltage system along the line, at calculated intervals, allows for optimum performance of the TLA, to give an increased system line voltage. Therefore eliminating the need to increase the standard insulation level required on conventional system upgrade.

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.

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.
