4. Effect of current sensors on the features and functions of digital protection

   The principles currently used in the protective function of the digital protections are generally based on the evaluation of analog signals in current and voltage of the protected object. This input analog signals have been provided by instrument transformers from the origin of electrical protections. With the advent of sensors that are increasingly replaced the above conventional instrument transformers, is to be expected qualitatively and quantitatively different type of input signal to digital protection. With respect to this fact, may also be reviewed a number of protective functions, which the concept was based just on the cooperation with conventional current instrument transformers. This work should consider the influence of the used transducers (Rogowski coil or current transformer instrument) to a particular protective function and not only with regard to the parameterization, but also on the principles used to evaluate the fault states of protected system.
