Rated current IN 1 A, 2 A or 5 A Rated voltage UN 100 V or 200 V Rated frequency fN 50/60 Hz Thermal ratings: continuous for 10 s for 1 s surge (half-cycle) 4 x IN 30 x IN 100 x IN 250 x IN (peak) Thermal rating of voltage circuit: continuous during 10 s 2.25 x UN 4 x UN Burden of the current inputs Burden of the voltage inputs <0.2 VA/input at IN 2 IN - for I∆ ≤2 IN ≤30 ms ≤50 ms Accuracy of pick-up value of g ±5% IN (at fN) Features: • For two- and three-winding transformers • Three-phase function • Current-adaptive characteristic • High stability for external faults and current transformer saturation • No auxiliary transformers necessary because of vector group and CT ratio compensation • Inrush restraint using 2nd harmonic Settings: g-setting 0.1 to 0.5 IN in steps of 0.1 IN v-setting 0.25, 0.5 b-setting 1.25 to 5 in steps of 0.25 Max. trip time (protected transformer loaded) - for I∆ >2 IN - for I∆ ≤2 IN ≤30 ms ≤50 msconventional protection equipment. The following data can be viewed: a) The system values as measured by all protection functions. The corresponding functions do not have to have picked up for this purpose. b) Analog inputs. The amplitudes, frequency and phase relationships of all the analog inputs can be viewed without jeopardizing the operation of the protection functions. c) Digital input and output signals. The status of each signal can be viewed. Apart from the self-monitoring routines, the fact that the measurement data can be viewed all the way from the input transformers to the digital signals also confirms the correct functioning of the digital processors and the data bus. Using software HMI „Test functions“ The desired protective function may be selected from the list of available active functions. The test operation is based on simulated numerical values. One or more channels may be selected for testing the tripping or signalling outputs. The test function is mainly used for commissioning purposes when the system is out of service. Redundancy Hardware and software redundancy is adapted to the functional requirements. Two independent groups of protection functions are accommodated in either two separate hardware racks or in only one rack, but with two completely independent hardware groups. Injection testing A 100% test of the system can be carried out by injecting test voltages and currents using, for example, a test set type OMICRON. Provision is made for injection testing with a test set at the terminals of the input transformer assembly 216GW62. The terminals enable primary system PT circuits to be interrupted and CTs to be short-circuited.
