 | | | | | - 8 models and 9 protective elements | | | | - Implements 0.5 class measurement precision through a dedicated protection and
measurement algorithm.
- Displays measurement values using 4-line VFD to allow easy identification.
- If an accident occurs, the screen automatically displays the accident situation to
show the cause of the accident. | | | | | | | - Uses standard protocol Modbus to ensure compatibility of communication.
- Use of ProNET-iMC enables high-speed communication.
- Adopts composite data transmission method which acquires all data by a single request to improve the response
speed of a main system. | | | | - HRR enables convenient configuration of a monitoring panel via telecommunication, by providing 8 auxiliary input
points in addition to CB ON, OFF input whose status is displayed on the front of a relay. | | | | - Microprocessor and self diagnosis function by hardware improve system reliability.
- Has built-in SOE function used to save the accidents and change of values. | | | | - A single unit includes protection, measurement function, switches and display lamps to simplify wiring work and
cost when creating a panel.
- One can set the CT and PT ration in 1A and 1V units by manipulating the front key, so they are applicable to all
systems.
- Draw-out type enabling easy maintenance.
- Allows one to know the breaker replacement timing by providing the number of breaking times of a breaker, and
conducting period information. | | | | | | | Item | HPR-MD | HPR-FD | HPR-TR | HPR-OC | HPR-ROC | | | HPR-FD/G1 | HPR-FD/S1 | HPR-
