Abstract
Phase difference measurement between two sinusoidal electric voltages using three voltmeter method is presented. Uncertainty of phase difference measurement is evaluated in two methods: according to Guide for expression of uncertainty in measurement (GUM) and according to Supplement 1 to GUM - Propagation of distributions using a Monte Carlo method. Those results for measurement uncertainty are compared.
