Disturbance recorder function

The three conductor currents, the current in the directly earthed conductor,

binary signals, and the voltages, can be recorded in each BU. 

Recording can be started, for example, by a protection function or an input signal. 

The disturbance recorder data are stored in the REB 500. 

They can be read out directly on the BU or at the central unit in COMTRADE format and stored on the PC. 

An evaluation program (eg, WINEVE) is used for further processing.

REF542plus Multifunction Protection and Switchbay Control Unit integrates all the secondary functions in a single unit. 

This multifunctional unit also features a selfmonitoring function. 

All functions are designed as freely configurable software modules. 

Therefore, a wide range of operation requirements in MV stations can be met without any problems. 

The versatility of the software makes it possible to use the REF542plus on every 

switchboard independent on the specific application required.

Overcurrent-time protection

This is a back-up protection function which is calculated locally in the BU and used to provide simple,

autonomous feeder protection in each BU.

REF542plus success story

„ Market launch 2000

„ Delivered units approx. 50,000

„ Applications ranging from low voltage to high voltage

„ In service worldwide

„ Many different protection and control functions

Event recording

All events are stored with a resolution of 1 ms in the central unit and in the BUs.

System, protection and test events can be generated.

Protection events refer to the protected busbar and include the changes in the disconnector and breaker positions,

trips, etc. Test events are recorded during testing with the test signal generator.

System events describe the diagnostic and fault messages of the NBP system as a whole.
