摘要:
A leakage current measurement apparatus for measuring leakage currents is disclosed. The leakage current measurement apparatus automatically selects one of non-inductive shunt resistors of 10Ω, 100Ω, and 1000Ω and measures leakage currents of an outdoor isolation material for an ultra-high voltage. Additionally, the leakage current measurement apparatus is capable of measuring a relatively wide range of leakage currents with a relatively high precision, even at a remote location, as a measurement range is automatically adjusted within measurement ranges preset by a user when leakage currents of an outdoor isolation material change, and being protected against a surge possibly generated by an ultra-high voltage. Also, it can remotely measure in real-time leakage currents of an outdoor isolation material installed at a remote location over Ethernet.

A washing machine including a drying apparatus. The washing machine including the drying apparatus quickly dries wet laundry by efficiently condensing and adsorbing vapor from humid air of high temperature flowing from a water tub during a drying-mode operation. The drying apparatus includes a condensing duct and a blower duct respectively mounted on a rear surface and an upper surface of the water tub. The condensing duct has an ultrasonic atomizing unit, a condensing unit and a water adsorption unit therein, while the blower duct has a blower fan and a heater therein. An inner space of the condensing duct is partitioned into a first condensing path, a second condensing path and a third condensing path by a first air guide and a second air guide. The ultrasonic atomizing unit, the condensing unit and the water adsorption unit are installed in the first condensing path, the second condensing path and the third condensing path of the condensing duct, respectively, thus condensing and adsorbing vapor from the humid air which sequentially passes through the first to third condensing paths, thereby dehumidifying the air providing dry air which is fed to the water tub to dry the wet laundry.

A piezoelectric motor for generating an elliptic motion by adding a longitudinal vibration to a bending-direction vibration is provided. The piezoelectric motor includes a piezoelectric member which generates a first vibration mode and a second vibration mode simultaneously by an applied power and a frictional member of which a portion is insertedly attached into a concave portion indentedly formed on one side of the piezoelectric member, wherein the frictional member is in an elliptic motion by the vibration generated by the piezoelectric member, so that an influence of the attachment of the frictional member to a resonance frequency can be minimized. Accordingly, a driving efficiency of the piezoelectric motor can be improved. In addition, attachment strength of the frictional member can be improved.
