Abstract
In order to protect a load from surges which may occur on an AC line, a pair of metal oxide varistors (MOV) are serially coupled across the AC line. A series circuit of a gas tube and a capacitor is coupled from the terminal which joins the two varistors to ground.
Claims5
A surge protector for protecting a load from surges which may occur on an AC line coupled to said load, said surge protector comprising a pair of impedances coupled across said AC line, and a series circuit of a spark gap and a capacitor coupled to said impedances.
