전위차 해소기 SGP는 안테나, 파이프, 건물 옥상의 구조물 등 접지가 연결되지 않은 설비라인에 연결하여 설비라인에 직낙뢰가 칠 동안 표면 방전으로 인한 위험을 감소시키기 위해여 설치 

This spark gaps are designed to protect metallic elements,
like anttennas,poles,pipes,roofing equipment...which are not
conne
cted to earth for operation reason, against the risk of
flahover dring a lightning strike on the installation.

When a large or exposed metallic element is not connected,
for operating reasons, to connect between the element and
the grounded structure (or lightning conductor) a spark gap,
which allows a puctual and a brief connection to earth during
the lightning strik.

In stand-by situation, the spark gap insulates the elem-
ent from the earth. During the lightning strike, the spark
gap fires to create equipotentiality and to avoid destru-
ctive flashovers.


SGP 의 특징Air spark gap with high sparkover voltage (1000 and 2500 
V) and heavy discharge current. Connection on threaded 
pin.
