The surge arrester comprises of a number of ZnO elements situated within a Porcelain housing and sealed against moisture ingress. TE Connectivity HV surge arresters are designed and manufactured to the current IEC : 2014 standard and the following tests have been successfully performed: Test performed on metal oxide blocks: IEC Clause 8.3 Residual voltage test IEC Clause 8.4 Test to verify long term stability under continuous operating voltage IEC Clause 8.5 Test to verify the repetitive charge transfer rating, Q rs * IEC Clause 8.7 Operating duty test IEC Clause 8.8 Power frequency voltage versus time test IEC Clause 8.15 Test to verify the dielectric withstand of internal components Test performed on complete surge arresters: IEC Clause 8.6 Heat dissipation behavior of test sample IEC Clause 8.10 Short-circuit test IEC Clause 8.11 Bending moment test IEC Clause Seal leak rate test IEC Clause 8.14 Radio interference voltage (RIV) test Insulation withstand tests on surge arrester housing: IEC Clause 8.2 Insulation withstand tests include Dry lightning impulse Wet power frequency Wet switching impulse *New test introduced in the IEC : 2014 standard.

3 DESIGN CONCEPT Aluminium end flange Pressure relief diaphragm The seal design for porcelian surge arresters is a critical componant of the surge arrester to ensure a long service life. To prove the seal design the following development and verification tests were carried out. Ageing test on seal material Environmental and pollution test Mechanical and seal leak test Porcelain Housing ZnO Varistors Locating ring HV surge arrester helium leak test chamber for routine testing Aluminium spacer Vent ports PAGE 3

12 Surge Counter options The TE Connectivity range of surge counters and monitoring instruments are fully tested for use with any manufacturers ZnO surge arrester. The surge counters, are designed for installation in the earth connections of a single phase surge arrester. The SC12 can be installed to used on a 3-phase set of arresters Fully weatherproofed and sealed for life they are housed in a one piece gravity die cast aluminium case, epoxy powder coated to enhance its already high degree of resistance to surface corrosion. SC12 The glass viewing window (SC12 and SC13) is sealed in place using a silicon rubber adhesive, and a desiccant 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 M12 bolt supplied. Available options: SC12 The SC12 gives a visual indication of the quantity of surges the arrester has received; this is via an integrated 6 digit cyclometer. The SC12 can be supplied with an auxiliary volt free contact rated at 1 A V for connection to remote signalling equipment. SC13 SC13 The SC 13 provides the additional measurement of total leakage current. The analogue instrument provides a means of monitoring the leakage current through the surge arrester and over the surface of the surge arrester housing. Significant changes after installation may indicate deterioration in the surge arrester or a build up of surface contamination. The SC13 can be supplied with an auxiliary volt free contact rated at 1 A V for connection to remote signalling equipment.
