Title:
CURRENT MEASUREMENT ADAPTER DEVICE FOR VOLTAGE-CURRENT MEASURING INSTRUMENT OF THREE-PHASE POWER
Document Type and Number:
WIPO Patent Application WO/2022/114419
Kind Code:
A1
Abstract:
The present invention relates to a current measurement adapter device used in a voltage-current measuring device of three-phase power and, more specifically, to a current measurement adapter device capable of preventing a wiring error of multiple terminals when measuring current by using a voltage-current measuring device. In a current measurement adapter device for a voltage-current measuring device of three-phase power according to one aspect of the present invention, the voltage-current measuring device of three-phase power has: a voltage measuring terminal having two R terminals, two S terminals, and two T terminals formed therein; and a current measuring terminal having an Ri terminal, an Ro terminal, an Si terminal, an So terminal, a Ti terminal, and a To terminal formed therein, wherein the current measurement adapter device may be detachably mounted on the voltage measuring terminal such that the two R terminals communicate with each other, the two S terminals communicate with each other, the two T terminals communicate with each other, and only any one R terminal, any one S terminal, and any one T terminal are externally connected. According to the present invention, when the current measurement adapter device is mounted on the voltage-current measuring device, an operator can measure the current without separately connecting the voltage measuring terminal and the current measuring terminal. Accordingly, it is possible to prevent an error that may be caused due to incorrect wiring between the voltage measuring terminal and the current measuring terminal.
