STAND FOR TESTING THE FUNCTION OF HIGH-VOLTAGE VOLTAGE TRANSDUCERS Russian patent published in 2022 - IPC G01R31/28 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and can be used to test the function of voltage transducers intended for measuring and converting a primary DC voltage signal in the 0 to 1,500 V range into a proportional current signal in the 0 to 5 mA range. The stand includes a measured signal unit, a meter unit, a data recording unit, and a power supply unit, interconnected by means of electric cables, wherein the measured signal unit and the meter unit are placed in a control panel made in the form of an industrial body. The measured signal unit is made in the form of a miniature high-voltage DC voltage source, and an interface converter unit is additionally installed between the meter unit and the data recording unit, intended for galvanic isolation of the series interface and protection of the USB port against pulse interference.

EFFECT: arrangement of a workplace for testing the function of voltage transducers with a high DC input voltage in the 0 to 1,500 V range without applying large-sized high-voltage equipment, thereby ensuring the electrical and fire safety during work and leading to a reduction in the overall dimensions of the stand, as well as allowing testing of the function of high-voltage transducers both in the manual and automatic modes.
