发明名称 Voltage detector with improved accuracy
摘要 The present invention is a voltage detector that is capable of measuring AC voltages, especially the high voltages encountered by electric utility linemen, with improved accuracy. To obtain these improvements in accuracy the present invention includes a novel circuit, which can be incorporated into a standard digital voltage detector. This circuit is able to accurately determine the magnitude of external capacitive reactance, which allows the voltage detector to compensate for variances in the external capacitive reactance that, if uncompensated, could adversely affect the voltage measurement; consequently, this invention provides the user with an AC voltage detector having improved accuracy characteristics.
