Title:
VOLTAGE MEASUREMENT DEVICE AND VOLTAGE MEASUREMENT SYSTEM
Document Type and Number:
Japanese Patent JP2016101005
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a voltage measurement device having a transformer that is small in size and can be easily attached for measuring a residual voltage.SOLUTION: The voltage measurement device includes a first capacitor whose one end is electrically connected with a power line of a motor. A second capacitor is connected between the other end of the first capacitor and a reference voltage source. The transformer is connected in parallel to the second capacitor. The voltage measurement instrument is connected with the transformer and measures a voltage based on a residual voltage of the motor.SELECTED DRAWING: Figure 1
