    An advanced kWh-meter can be used simultaneously both for versatile billing tariff measurements and for power quality monitoring. The needs and potential for developing dip measurements, and experience with new fairly inexpensive sparse sampling kWh-meters, are discussed. The effects of sparse sampling on the accuracy of voltage dip measurements impose on the sampling rate are analyzed. Priciples, simulations, laboratory tests and field measurements are presented. Evaluation of phase-to-phase dips from phase to neutral measurements are also discussed. The sampling rate of the tested meter was about 409 Hz. The ability to measure voltage dips has been quite an important new feature of this kWh-meter and has promoted its use.
