Abstract
An arrangement for temperature measurement at high-voltage potential is disclosed. The energy for measuring the temperature of an optical current transformer is provided by a single photodiode. The photodiode is supplied by light emitted by a light source and guided to the photodiode via an optical waveguide.
Claims16
A device for measuring a temperature at a high-voltage potential, comprising:
- an optical current transformer at a high-voltage potential,
- an electronic temperature sensor configured to measure a temperature of the current transformer, the electronic temperature sensor having exactly one photodiode,
- a first light source configured to emit light,
- a first optical waveguide configured to guide light emitted by the first light source to the photodiode of the electronic temperature sensor,
- a second optical waveguide configured to transmit data indicating the temperature measured by the electronic temperature sensor to a ground station.
