SURGE COUNTER

摘要

A surge counter is disclosed for absorbing and counting current surges in power supply lines or communications lines. The counter comprises a plurality of parallel surge absorbing elements each having a specific impulse discharge starting voltage, connected to surge invadable lines. The surge absorbing elements each include a gap type discharge tube connected to a nonlinear resistor. A light sensitive element is placed close to each of the discharge tubes in a light receiving relationship therewith for detecting the light emitted thereby, and a counter circuit is provided in series with each light sensitive element for counting the signals generated by the light receiving elements. Surge current values are accurately sorted and the number of invading surges is counted using a simple and reliable circuit design.
