专利汇可以提供Electrical device having current limiter and spark gap专利检索,专利查询,专利分析的服务。并且An electrical device such as a watthour meter has a movement located within an enclosure. Terminals pass through the enclosure for the purpose of establishing connections between the device and an external circuit. A spark gap is secured to the enclosure and is positioned externally of the enclosure for the purpose of establishing a shunt path to ground for surges appearing on the external circuit. A silicon carbide block is located internally of the enclosure and is connected in series with the spark gap for the purpose of limiting the current flowing through the spark gap after breakover of the gap takes place.,下面是Electrical device having current limiter and spark gap专利的具体信息内容。
