A method for enabling communication of data relating to samples of electric measurements, the method being performed in an intelligent electronic device, IED, including a cellular radio module, the IED being configured to protect power system equipment. The method includes the steps of: detecting channel quality using the cellular radio module, the channel quality relating to a channel between the IED and a base station; transmitting packets using the cellular radio module, each packet including data relating to samples of electric measurements for protecting power system equipment; and increasing sample rate of the electric measurements when the channel quality is worse than a first threshold.
