摘要（英）：

The invention provides a GIS zinc oxide lightning arrester live-line tester for the purposes of realizing a GIS lightning arrester live-line test by obtaining voltage signals through a maintenance power supply or a 220 power supply in a station and reducing errors in the test. In order to realize the purposes, the GIS zinc oxide lightning arrester live-line tester comprises a host, a voltage isolator and a data transmission system, wherein the host comprises a reference signal input end, a current input end, a wireless signal receiving end and a grounding end; the voltage isolator comprises a reference voltage input end and a voltage signal output end; and the host is also internally provided with a phase detector, the phase detector is connected with a phase calibrator, and the phase calibrator is connected with the maintenance power supply or the 220 power supply in the station for obtaining the voltage signals. Through such arrangement, the GIS zinc oxide lightning arrester live-line tester can simultaneously measure three phases of an MOA, can also perform single-phase measurement and can automatically compensate interphase interference.
