ISM/TEL-12-20/630-150 Tavrida ISM series is the lightest and most compact medium voltage circuit breakers available on the market today. • All components are assembled along a single axis, with three mono-stable magnetic actuators (one per pole). • The actuators are mounted in a steel frame and are mechanically linked by a synchronizing shaft. • Long mechanical and interrupting lives • The actuators drive a pulling insulator that in turn connects to the advanced Tavrida vacuum interrupters at the top of the breaker. This single-axis design results in the highest reliability available today: Maintenance free with a total life expectancy of > 30 years, and up to 150,000 close - open operations. The Tavrida ISM can be installed in any orientation which makes it equally suitable to either new switchgear or retrofit applications. 19

SCHIRTEC – Lightning Conductor 21

SCHIRTEC – Lightning Conductor • The air terminal has enough size and quality to conduct the biggest lightning strike. Ion generator, induction coil and the protector have high impedance. The generator is located inside of a special epoxy resin. So ion generator is protected from the environmental conditions. • Accelerator and atmospheric electrodes are designed in a way that can be charged with different potentials and with this feature, it is aimed to make work of the electrodes as both additional ionization producing resource and as accelerator. The regulation is made with the number of electrodes and ion generator’s impedance, lets the difference protection capacities in the SCHIRTEC E.S.E Lightning Conductors All Early Streamer Emission lightning conductors are tested in compliance with NF C 17-102 standard. 22

SCHIRTEC OPERATION The efforts which have been carried out until today to increase the radius of action of the lightning conductors were based mainly on the improvement of the excitation time of the upward leader. However, the effectiveness of a lightning conductor does not depend only on the excitation time of a leader to the rod but as well and above all of the capacity to propagate this leader on a large distance to capture the downward leader. SCHIRTEC has developed a new revolutionary generation of lightning conductor and thus keeps its technology advance. The operating principle of the SA 60µs consists, not only to initiate the upward leader, but moreover, provides enough energy to ensure its propagation until the junction with the downward leader. 23
