Title: | Accuracy limit of high precision stochastic watt-hour meter | Authors: | Pejic D. Vujicic V. |
Issue Date: | 1-Jan-1999 | Journal: | Conference Record - IEEE Instrumentation and Measurement Technology Conference | Abstract: | Stochastic watt hour meters are applied with several differences: stochastic digital signal is derived from a two-bit A/D converter; the A/D converter is a two-bit flash converter with uniform dither; and the logic circuits are supplied with only one voltage. It was connected in distribution net in parallel with standard induction three phase watt-hour meter which accuracy class was 0.2. The maximum daily difference was 0.07%, typical daily difference was 0.03% and total difference was 0.01%. The instrument has advantages of simple hardware and easy implementation of parallel measurement. The idea is very convenient for application in multichannel real-time RMS, power and energy measurements. | URI: | https://open.uns.ac.rs/handle/123456789/13952 |
