The invention discloses an electronic sensing type high-voltage metering device and remote testing system. The electronic sensing type high-voltage metering device and remote testing system comprises a voltage sensor, a current sensor, an optical fiber transmission system, a merging unit, a remote testing system and a digitalized electric energy metering device, wherein the secondary outputs of the voltage sensor and the current sensor are digital optical pulse signals which are transmitted to the merging unit through the optical fiber transmission system; optical fiber signals output by the voltage sensor and the current sensor are merged and then are transmitted to the digitalized electric energy metering device through an optical cable; the digitalized electric energy metering device is connected with the remote testing system. The electronic sensing type high-voltage metering device and remote testing system has the beneficial effects that the optical fiber signals output by all the sensors are merged on the side of the sensors and are transmitted to the digital electric energy metering device through the optical cable, a secondary signal transmission loop is simplified, and the site construction workload is greatly reduced.
