Introduction

REB500 includes continuous comprehensive self-supervision and diagnosis of the software and
hardware components. By setting up a proper signaling scheme while commissioning the system, most
failures are signaled externally (see
failures in primary and secondary systems that influence the response of the protection. Other failures
that are not detected (for example, interrupted tripping circuit) are located and cleared while carrying out
periodic inspection and maintenance (see Commissioning manual). Checks and measurements while the
system is in normal operation (no active alarms) are therefore unnecessary.
An alarm (external or on the local HMI) can concern a failure in the REB500 system (for example,
hardware failure) or in the associated primary plant (for example, incorrect disconnector status signal).

Operation

5.3.1 Introduction
Operation in the case of the busbar protection system is confined to supervising the proper function of
the system and assessing the system data.
There are different ways of viewing operating, disturbance and tripping data:
•

Local HMI

• PC running HMI500
• Remote HMI
• Station automation system (SCS)
see Section

Section
Normal operation without any faults is also indicated by the fact that only the green
protection LED is lit and the alarm page LED is not lit on the local HMI.
Should the system generate an alarm, inform the trained maintenance personnel
responsible.
Checks and maintenance on the REB500 system may only be carried out by properly
trained personnel.
Only properly trained and authorized personnel should be in possession of the HMI500
password.
