Section 2 Safety information

GUID-7CDA9FB7-5CD6-4BD5-A1D2-AAB8E7BF87A3 v2

Dangerous voltages can occur on the connectors, even though the auxiliary

voltage has been disconnected.

Non-observance can result in death, personal injury or substantial property

damage.

Only a competent electrician is allowed to carry out the electrical installation.

National and local electrical safety regulations must always be followed.

The frame of the IEDs has to be carefully earthed.

Whenever changes are made in the IEDs, measures should be taken to avoid

inadvertent tripping.

The IEDs contain components which are sensitive to electrostatic discharge.

Unnecessary touching of electronic components must therefore be avoided.

3.1.1 Bay/Station protection — function overlapping signal

3.1.1.1 Signal designations

GUID-473B447A-C76B-4A92-923D-D0987D089E87 v1

The BP/SP function overlapping (general) signals correspond to the signal numbers

nomenclature of the station protection system (for details, see

REB500 Technical Manual

).

For example, 19205_Block BP (5 digit signal number)

3.1.1.2 Outputs generated by BP and used as SP inputs (default signals)

GUID-9B46ED80-5132-49AE-BD97-776AD0CFFAB8 v1

Table 1: BU_ BP outputs to SP inputs (default signals)

Parameter Description

11120_BP External TRIP This is the tripping signal generated by bay protection of REB500. It trips faults

on a line with the aid of the REB500 tripping contact. Tripping thus takes

account of the busbar configuration at the time. The signal is activated by the

bay protection directly and does not therefore appear as binary input signal.

11125_BP External TRIP BB

zone

This is a tripping signal generated by the bay protection of REB500 which is

used to trip the entire bus zone to which the bay is connected. The tripping

command is applied to all the bay units of the bus zone and sections of busbars

interconnected by an isolator (intertripping).

13210_BP Block BFP This signal is directly activated by the bay protection and doesn’t therefore

appear as a binary input signal. The operation of the breaker failure protection

of the corresponding feeder is blocked. When the blocking signal is cancelled

and providing a starting signal is present and current is flowing, the timers start

again at t = 0.

13610_BP Trip transfer Reserved for the special application “trip transfer”.

This signal is directly activated by the bay protection unit and does not

therefore appear as a binary input signal.

13761_BP Start BFP L1L2L3_5 This signal is functionally identical to signal 13760_Start BFP L1L2L3_5, but it is

directly activated by the bay protection and does not therefore appear as a

binary input signal.

13770..13780_BP Start BFP Lp Breaker failure protection with phase-selective starting (p = 1, 2 or 3). The

breaker failure protection timer starts when this signal is activated by BP

functions and the BFP measures a current in the corresponding phase. This

signal is directly activated by the bay protection and does not therefore appear

as a binary input signal.

13785_BP Start BFP L1L2L3 Breaker failure protection with three-phase starting. The breaker failure

protection timer starts when this signal is activated and the BFP measures a

current in any phase.

This signal is directly activated by the bay protection and does not therefore

appear as a binary input signal.

13790_BP External start BFP Breaker failure protection with three-phase starting. The breaker failure

protection timer starts when this signal is activated regardless of the current

measurement.

This signal is directly activated by the bay protection and does not therefore

appear as a binary input signal.

Parameter Description

13797_BP Start BFP L0 Breaker failure protection with L0 - starting. The breaker failure protection timer

starts when this signal is activated by BP functions and the BFP measures a

current in the neutral system. This signal is directly activated by the bay

protection and does not therefore appear as a binary input signal.

16760_BP Global Start DR Starts those disturbance recorders in the bay units that are configured. The

signal Central start DR in the bay units must be configured. This signal is

directly activated by the BP unit and does not therefore appear as a binary input

signal.

29110_BP TRIP Three phase tripping commands of the bay protection functions grouped to one

three phase tripping command.

29115_BP TRIP L1 Phase L1 tripping commands of the bay protection functions grouped to one L1

tripping command.

29120_BP TRIP L2 Phase L2 tripping commands of the bay protection functions grouped to one L2

tripping command.

29125_BP TRIP L3 Phase L3 tripping commands of the bay protection functions grouped to one L3

tripping command.

Table 2: BU_ Inputs to BP

Signal Description

19205_Block BP The BP output signals of the respective bay unit are blocked. (Internal

processing of the functions continues and therefore, measurements and

signals continue to be displayed on the local HMI.)

19600_Activation BP ParSet_1 The protection functions and settings assigned to parameter set 1 are

active. They remain active after the signal has been reset.

19605_Activation BP ParSet_2 The protection functions and settings assigned to parameter set 2 are

active. They remain active after the signal has been reset.

19610_Activation BP ParSet_3 The protection functions and settings assigned to parameter set 3 are

active. They remain active after the signal has been reset.

19615_Activation BP ParSet_4 The protection functions and settings assigned to parameter set 4 are

active. They remain active after the signal has been reset.
