Repair and replacement of electric and electronic equipment are expensive, and many industries spent quite a hefty amount due to the obvious ones. Theft and vandalism, which can be controlled and limited by incorportating secqurity and surveillance systems. Still, issues like lightning and power surges demand more and need to be tackled with well designed stringent measures.
While you have a plan to include in the lightning and surge protectin devices for your electric safety, it should be a complete and permanent solution per recommended standards. Safety standards evolve, Yet surge protectors are not something new or out of the ordinary. Surges can be generated due to artificial or natural phenomena where they induce into your facility to initiate fire and below off your electrica/ electronic equipment. Utilising surge suppression modules as per IEC 61643 and UL 1449 is an excellent investment for the effective detection of surge events, and voltage clamping has been around for decades.
There is always a necessity for such a protector as surges are frequent across attached components due to technological advancement in equipment manufacturing. We customize SPDs for every other application and the critical system as per appropriate voltage/current ratings. Surges are electrical faults that cause immense damage to a person and his property. Direct lightning is the real and the foremost cause for a surge of the overhead electric cables and transmission lines.
As per the standard, the site/ building is surveyed, and the risk assessment is conducted before installing the lightning protection system and surge protection devices. Lightning risk assessment is done IS/ IEC 62305 using the flecible design software, and then lightning strike density is evaluated for the particular area/ Zone. As per the level of protection, lightning arrester, down conductor mesh and earting systm is installed.
Further for indirectly generated surges inside the facility, we provide transient surge suppressioon unites based on voltage-controlled resistors and spark gaps (discharge paths), Metal oxide varistor, GDT, silicon avalanche diode, etc. or a combination of thse technologies can also be applied.
Details Regarding the Case of Surge Events:
Derect lightning imposes damage to your structure, and indirect surges, i.e. lightning effect, switchning surges and electromagnetic induction, etc., can cause damage to the equipment inside the system. Direct lightning is of waveform 10/350 microseconds which is the most dangerous from pushing unbearable current to pass through electric circuits and reaching the outlets. Intentional or unintentional whithching device malfunctioning or damages over an extended time.
Preventing This Short-Live Increase in Voltage Called Surge:
For protection from the devastating effect of lightning, strategies and designing of proper structural lightning protection is required as per IEC 62305. Here is the standard recommends using air terminals and a down conductor network connected to the ground providing various parallel paths for the lightning strikes to dissipate into the environment safely. Te traditional lightning rod and down conductors can be installed at the building's construction stage or an already existing structure and are ideal for intercepting lightning strikes.
For internal protection of equipment from surges, the surge suppressor complying with IEC 61643-11 and UL 1449 is potent and installed in the main switchboard or the electricity meter. SPDs effectively shield and adequately protect from high derect strikes in 10/350 and switching surges in 8/20 us and are an inevitable part of AC power installationn.
The Essential part of evety electronic protection system is the installation called maintenance free earthing system, which is the final stage to disconnect any fault occurrencces and divert it to the ground.

Because many equipment needs electricity, the power outlet needs a larger capacity because otherwise it will cause fire. However, if you play tunnel rush, you do not need the device that needs electricity to still play.
