Abstract
Sposób pomiaru polega na próbkowaniu stanu komparatorów porównujących wartości mierzonych wielkości z napięciem referencyjnym, a następnie dokonaniu obliczeń wartości skutecznej. Charakteryzuje się tym, że próbkowanie stanu komparatorów wykonuje się ze stałą częstotliwością i wszystkie wyniki próbkowania wprowadza się do bufora danych. Następnie z bufora danych do jednostki obliczeniowej przesyła się wyniki wybrane losowo za pomocą generatora impulsów o losowej długości czasu odstępu pomiędzy generowanymi impulsami uzupełnionego układem formującym sygnał losowy. Układ do pomiaru wartości skutecznych napięcia składający się z co najmniej jednego komparatora, źródła napięcia referencyjnego oraz jednostki obliczeniowej. Wyjście każdego komparatora (1) połączone jest z wejściem bufora pamięci danych (2), a wyjście sygnałowe bufora pamięci danych (2) połączone jest z jednostką obliczeniową (3). Ponadto do wejścia wpisującego bufora pamięci danych dołączony jest generator impulsów (4) o losowej długości czasu odstępu pomiędzy generowanymi impulsami uzupełniony układem formującym (5) sygnał losowy.The method of measurement consists in sampling the state of comparators comparing the measured values with the reference voltage, and then calculating the RMS value. It is characterized by the fact that the comparators state sampling is performed at a constant frequency and all sampling results are entered into the data buffer. Then, from the data buffer to the calculation unit, the results selected at random by means of a pulse generator with a random length of time between the generated pulses supplemented with a random signal forming system are sent. A system for measuring RMS voltage consisting of at least one comparator, a reference voltage source and a calculation unit. The output of each comparator (1) is connected to the data memory buffer input (2), and the signal output of the data memory buffer (2) is connected to the calculation unit (3). In addition, a pulse generator (4) with a random length of time between the generated pulses is added to the input input of the data memory buffer, supplemented with a random signal forming system (5).
