Toepassingen van D/I meetsystemen

IN POWER GRIDS VOLTAGES AND CURRENTS SHOULD BE RELIABLY MEASURED DURING OVERVOLTAGES, SWITCHING EVENTS AND FAULT SITUATIONS BUT ALSO DURING 50 Hz OPERATION. THE MEASURING SYSTEM WHICH LINKS THE POWER SYSTEM, FOR INSTANCE A SUBSTATION, TO THE DATA HANDLING, SHOULD CORRECTLY ADAPT THE SIGNALS TO THE MODERN ELECTRONICS. OTHER SPECIFICATIONS ARE THE SYSTEM’S EMC QUALITY, ITS BANDWIDTH, LINEARITY AND COST AND ITS APPLICABILITY IN OPEN AND CLOSED SUBSTATIONS. A COMPLETE SYSTEM IS DESCRIBED THAT EXCELLENTLY FITS ABOVE REQUIREMENTS. THE APPLIED DIFFERENTIATING/INTEGRATING PRINCIPLE IS SIMPLE, HAS A LARGE BANDWIDTH AND HIGH EMC QUALITY, AND CAN BE USED WITH LONG COAXIAL CABLES. GLASS FIBERS ARE NOT NEEDED. WE APPLY THE SYSTEM IN OUR HIGH-VOLTAGE WORK, FOR SUBSTATION MEASUREMENTS AND IN MANY THIRD PARTY EMC PROJECTS, OFTEN WITH RESPECT TO LIGHTNING PROTECTION
