Title:
LOW-POWER VOLTAGE TRANSFORMER HAVING TEMPERATURE COMPENSATION APPLIED THERETO, AND TEMPERATURE COMPENSATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/076128
Kind Code:
A1
Abstract:
The present invention relates to a low-power voltage transformer having temperature compensation applied thereto and to a temperature compensation method thereof, wherein the reliability of measured values can be increased for temperature changes in a low-power voltage transformer, and the temperature standard of IEC61869-6 is satisfied by attaching and calibrating temperature sensors around the low-power voltage transformer. The low-power voltage transformer having temperature compensation applied thereto of the present invention comprises: a voltage sensor to which a first temperature sensor is attached and which senses the voltage of a digital transformer; and a secondary converter to which a second temperature sensor is attached and which performs secondary conversion to transmit measured voltage information to a merging unit.
