Our homes and businesses are highly reliable on continuous uninterrupted power supply. But transient over voltage and direct/indirect lightening strikes can give major damages to the home and commercial appliances. In these cases we use Surge Protection Devices. There are many devices available in India. Some of them are below.

Type 1 SPDs : Used for Low Voltage Distribution and direct lightning strikes
Type 2 SPDs : Used generally in  Distribution/ Transmission system and indirect lightning strikes
