| Presentation | The application of powerful microprocessors with MR and IR-relays of the HIGH TECH RANGE provides a large variety of advantages over power protection systems of the traditional type. The MR-protection relays are based exclusively on the microprocessor technology. They represent our most efficient generation of power protection systems. Because of their capabilities to process measured values digitally and to perform arithmetical and logical operations, they are superior to the traditional analog systems. Besides, the digital protection relays offer important additional advantages such as very low power consumption, adaptability, flexible construction, selection of relay characteristics etc. The IR-protection relays are based on the microprocessor technology or on the analog technology. They represent a more cost saving generation of relays of the HIGH TECH RANGE, used for basic equipment protection. The IR-protection relays are superior to conventional protective devices because of their following characteristics: Integration of multiple protective functions into one compact housing User-friendly setting procedure by means of DIP-switches Compact construction type by SMD~technology MR-protection relays are used for more complex protective functions, such as earth fault directional detection, and also in cases where easy operation, quick fault-analysis and optimal communication capabilities are required. All relays of the HIGH TECH RANGE are available for flush mounted installation, as well as for rack mounting. Plug-in technology is used. Of course, all relays comply with the IEC/DIN regulations required for the specific protection application. |
