How TSTLP® Early Streamer Emission (E.S.E.) Lightning rod works ?
Check Flash Video at http://youtu.be/wxpmdJ9BBRk
A: TSTLP® ESE terminal’s lower electrodes gather energy from naturally occurring ambient electrical fields that increase as much as ten thousand volts per meter as the storm approaches.
B: TSTLP® ESE terminals collects the electrical energy and stores in capacitors inside the TSTLP® ESE terminal. Just before a lightning strike the atmospheric electrical field increases rapidly,activating the patented triggering device.
C: TSTLP® ESE terminal’s trigger releases the stored energy in the capacitors through the upper electrodes at the tip of the air terminal and initiates an upward leader at the optimum moment.
D: TSTLP® ESE terminal’s upward leader connects with the downward leader and the result is a lightning strike that directed safely to ground through the air terminal, downleads, and grounding system.
Lightning Surge Protection is NECESSARY !!!
Each year there are million and million of lightning strikes all over the world.The enormous energy of lightnings have inflicted huge damages to propertyand also endanger human lives, to avoid these damages, lightning/surge protection devices shall be installed.In present days, with the rapid development of electronic communicationdevices & much more sensitive operational voltages, these led to equipmentcan be easily damaged by lightning & surge.

Sources of Lightning/Surge
Lightning strike includes direct lightning strike, close lightning strikeand distant lightning strike (Fig.3).The amplitudes and energy of theimpulse currents and voltages generated are especially dangerousto the electronic system to be protected.
Due to the existence of the earthing resistance, a direct or closelightning strike may cause a high voltage drop from earthing resistance to the distance surrounding, this is a great threat to theelectrical & electronic equipment in the building. Besides the highvoltage drop at the earthing resistance, the induction of theelectromagnetic wave caused by the lightning will also producesurges to the system & equipment (Figure 3: 1c).
Distant lightning strike is that the strike point is at a distance fromthe protected devices, or striking at the high voltage overhead linesand its vicinity, or the lightning discharge between the clouds(Figure 3: 2a,2b,2c).
Surge caused by switching operation
— Open or close electrical circuit on inductive load(e.g. Transformer, magnetic core, motor)
— Ignition or interruption of electric arc(e.g. arc welding Device)
— Operation of circuit breaker
Lightning discharge
All conductors may conduct lightning current(Figure.4).Such as:
۱٫ Power supply lines
۲٫ Data lines
۳٫ Air termination devices (or earthing system)
۴٫ Antennas
Figure 4: All conductors may conduct lightning current
Step voltage
When lightning occurs, the adjacent trees could become a conductorfor lightning current, if the lightning strikes the trees,a huge voltagedifference will be formed around the trees because of the largecurrent. If a man’s feet standing on the ground separately, a deadlystep voltage difference U will develop, this voltage difference could Obe life threatening(Figure 5).
Figure 5: Step Voltage
Lightning protection system is consisted of:
external lightning protection and internal lightning protection.
External lightning protection includes:
* Air termination device (lightning rod, belt and grid);
* Down conductor;
* Earthing system
Internal lightning protection includes:
* Shielding;
* Equipotential bonding;
* SPD installation
External Lightning Protection Mainly for Building & Structure Internal Lightning Surge Protection for Electronic Equipment
