Productomschrijving

All MR protection relays are based on microprocessor technology. They present the generation of our most efficient protection relays, because of their capabilities to process the measuring values digitally and to perform arithmetical and logical operation.

Additional advantages such as very low power consumption, adaptability, possibilities for selfsupervision, flexible construction, selection of relay characteristics are completely utilized. Some IR protection relays are based on microprocessor and some on analog technology. They present our low-priced protection relay generation and are used for all basic protection application.

The following properties of the IR protection relays, such as:
• Integration of multiple protection functions into one compact housing,
• User-friendly setting procedure by means of DIP-switches,
• Compact design due to SMD-technique,
are their superiority over the traditional protection systems.

For all applications of a more complex nature, e.g. directional earth fault detection and where operating convenience, fault analysis and communication ability are required, MR-relays are used. All relays of the HIGH TECH LINE are available for through panel mounting and in 19“ racks. Connection terminals are of plug-in type. All IEC/DIN regulations required for the individual application are reliably met by these relays.

The voltage relay IRU1-DC is used for supervision of DC voltages. This relay is used e.g. for supervision of intermediate circuits, station batteries or starter batteries.

The voltage supervision relay IRU1 generally protects power generating systems, consumers or electrical equipment in case of under- or overvoltage. Among other the relay can be used:
• to detect voltage increase or decrease in power-generating systems and energy supply networks
• to protect from dangerous overvoltage in case of a faulty voltage controller
• to protect motors against undervoltage
• to protect the generator stator against earth-fault (IRU1-E only)
• earth-fault supervision in isolated or compensated networks (IRU1-E only)
