AC STANDARD FOR ELECTRIC POWER QUALITY INDEXES CALIBRATOR
Abstract
Transfer measurements from the standard of direct voltage to the standard of alternative voltage is widely used in measurement and instrumentation. Well known method is based on the usage of thermo converter of voltage. There are some drawbacks of this method such as instability of error, hand mode of calibration and inertia of reproduction process. The new method of reproduction AC (AV) value proposed by usage of inertia’s properties of links of the parallel-resonance circuit to transfer measurements from the standard of direct current to the standard of alternative current. The paper illustrates the mechanism of action of AC-calibrator based on proposed method of reproduction, where AC signal is coming through L-inductor without its changes.
