Surge Arrester

A surge arrester works by diverting the extra voltage into the earth wire, rather than flowing through the electronic devices, while at the same time allowing the normal voltage to continue along its path.

Surge Arrester: is a device used to protect the electrical installations and equipment from electrical surges and transient voltage caused by electrical faults, switching, short circuits, sparks and lightning etc. Surge arresters are installed inside the panels to cancel out the surges.

Lightning Arrester: is a device used to protect the electric circuit and connected devices from the lightning strikes having high voltage transient surges. Lightning arresters are installed outside to ground the harmful effects of lightning spikes.

Surge Suppressor: Also known as transient suppressor or surge protector is a device installed in the home panel board to protect the connected circuits from electric surges and voltage spikes known as transients.

Lightning Rod: It is a device installed on the height location i.e. top of the building and transmission towers to provide a path to ground the lightning strokes. The lightning rod protects the structure from lighting surges.
