Lightning Arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arrester has been designed and type tested according to IEC standard. Standard.

As the ground charge builds immediately before the lightning strike, the lpi stormaster ese air terminal accumulates ground charge. In the instant before the strike, when the stepped leaders are branching down from the cloud, the stormaster ese terminal emits a series of pulses of ground charge, forming a streamer from itself before streamers emit from other structures. Its streamer reaches the stepped leaders before competing streamers, thereby winning the competition. Ground charge accumulation and streamer triggering is done by lpiÆs stormaster ese air terminal.
