HOW DOES DUVAL SURGE ARRESTOR PROTECT MY ELECTRICAL AND ELECTRONIC EQUIPMENT?

When lightning strikes and hits the ground, lightning current will travel underground to enter our building via the incoming cable through the main switchboard and damage our electrical equipment. Grounding system works by transferring the lightning current at the ground to the earth chamber, and then the earth chamber will function to discharge the current. Therefore, it is recommended to check the grounding system once a year due to the soil resistance level.

WHEN LIGHTNING HAPPENS, WHY MY ELECTRONIC EQUIPMENT IS ALWAYS DAMAGED BY LIGHTNING?

All type of electronic equipment are subjected to lightning damage if it is not protected by lightning surge arrestor. To protect them from lightning damage, it should be protected with both Duval Powerline surge arrestor at the main incoming switchboard and Duval Dataline surge arrestor to protect the computer, key phone, home theatre, CCTV and etc.

DURING THUNDERSTORMS, MY HOUSE INCOMING SWITCHBOARD ALWAYS TRIPS AND CAUSES ME MUCH INCONVENIENCE. HOW TO PREVENT THIS? CAN SURGE ARRESTOR HELP?

Frequent tripping occurring during thunderstorms can be due to nuisance tripping, for example, tripping caused by sudden high voltage, and not because of leakage in your electrical switchboard. For this nuisance tripping happening during thunderstorm, it is recommended to install both Duval surge arrestor and Duval RCCB with auto reset system to reduce inconveniences. Any RCCB in a switchboard will trip if leakage power is detected. Previously we have to manually turn on the RCCB when tripping occurs. Now we have Duval Auto Reset which function by automatically turning on the RCCB when tripping occurs. When there is nobody in the house when tripping occur, the electronic equipment such as refrigerator, aquarium water pump, and others will function normally after installing Duval RCCB with auto reset system

HOW DO WE PROTECT OUR HOUSES FROM DIRECT LIGHTNING STRIKES?

Installation of Satelit+G2 ESE lightning conductor can protect your building from direct lightning strike. Satelit + G2 ESE lightning conductor functions by capturing the lightning at the highest possible point before it strike and transfer it to ground via the properly installed earthing system.

WHY AFTER INSTALLING OF THE SATELIT + G2 ESE LIGHTNING CONDUCTOR, THE ELECTRIC EQUIPMENT INSIDE MY HOUSE ARE STILL BEING DAMAGED BY LIGHTNING?

Satelit + G2 ESE lightning conductor is installed to protect building structure, roof top and surrounding area. For electric equipment within your house, you need to install suitable models of Duval Lightning Surge Arrestor at the incoming switchboard or at sub switchboard located within your house.
