Abstract
A lightening arrestor system (30) for a pad mounted distribution transformer (18') incorporated in an underground loop distribution circuit has a lighting arrester (32) secured to the transformer parking stand (P) and attached to the pad ground connection. The arrester has a well (38) into which a cable elbow (A) formerly mounted upon a primary terminal bushing (H1B) is inserted. The arrester includes a varistor assembly including metal oxide disks (58). An elbow arrester (24') is mounted upon the terminal bushing which formerly mounted the cable elbow. The arrester obviates the employment of a feed-through device (28).
