Accessories - AS0094500 GNSS Surge Protector

Summary Information

Protects the GNSS receivers from surges and transients.

Full Description

GNSS receivers are very sensitive devices and are vulnerable to a phenomenon known as voltage surges and electrical transients. Sources of electrical surges are numerous. The most common is a nearby lightning strike, which affects nearby lines through induction. Industrial transients are also significant because they are man made disturbances caused by switching and commuting of electrical motors. The operation of such devices can cause abrupt shifts in the ground potential that can generate a current flow through a nearby cable in order to equalize the ground potential.
