A development of a high-voltage high-resolution digital sampling wattmeter system for on-site/in-situ calibrations of metering systems for high-voltage power/energy measurements is described in the paper. The current input uses an optically isolated hybrid two-stage current transformer with electronic circuitry that performs A/D conversion. Data is transmitted to a ground station through a fiber optic...
The development of a high-voltage (HV) current measurement system for on-site/in-situ calibrations in power systems is described in the paper. The system is based on an optically isolated hybrid two-stage current transformer with electronic circuitry that performs A/D conversion. It uses a fiber optic link for data transmission to a ground station and a laser-driven fiber optic link for supplying...
The development of a high-voltage reference current measurement system for on-site/in-situ calibrations in power systems is described in the paper. The system is based on an optically isolated hybrid two-stage current transformer with electronic circuitry that performs A/D conversion. It features a fiber optic link for data transmission to a ground station, and a laser-driven fiber optic link for...
