1) "Io measured" is always used.
2) "Uob measured" is always used.
3) Master trip is included and connected to the corresponding HSO in the configuration only when the BIO0007 module is used. If additionally the ARC option is selected, ARCSARC is
connected to the corresponding master trip input in the configuration.
4) The Iunb measurement values are taken from this block and put in the Measurent view.
5) Power quality option includes only current total demand distortion.
6) Power quality option includes current total demand distortion, voltage total harmonic distortion, voltage variation and voltage unbalance.
7) Available only with IEC 61850-9-2
8) Available only with COM0031-0037

3. Protection functions

The relay offers three-phase overload protection with
undercurrent and reconnection inhibit functionality for
capacitors, single or three-phase current-based unbalance
protection for capacitors including compensation for natural
unbalance and a current-based switching resonance
protection.
The relay features non-directional overcurrent and thermal
overload protection as well as non-directional earth-fault
protection.
Additionally, the standard configuration B includes directional
earth-fault protection, residual voltage protection, overvoltage
protection and undervoltage protection functions.
Enhanced with optional hardware and software, the relay also
features three light detection channels for arc fault protection of
the circuit breaker, busbar and cable compartment of metal-
enclosed indoor switchgear.
The arc-fault protection sensor interface is available on the
optional communication module. Fast tripping increases staff
safety and security and limits material damage in an arc fault
situation. A binary input and output module can be selected as
an option - having three high speed binary outputs (HSO) it

further decreases the total operate time with typically 4...6 ms

4. Application

REV615 is intended for the protection of capacitor banks used
for reactive power compensation in utility substations and
industrial power systems. REV615 offers protection
functionality especially for H-bridge, double star and single star
connected capacitor banks and the feeder cable.
The protection relay can also be used for the protection of
harmonic filter circuits, if the highest significant harmonic
component is the 11th.
Standard configurations A and B offer three-phase overload
protection, unbalance protection with compensation for natural
unbalance and switching resonance protection for capacitor
banks. An integrated undercurrent function in the overload
protection function block detects the disconnection of a
capacitor bank and inhibits the closing of the circuit breaker as
long as the capacitor bank is still partially discharged. A three-
phase thermal overload protection can be used for the thermal
protection of the reactors and resistors in the harmonic filter
circuits. The relay features non-directional overcurrent and
earth-fault protection for the feeder cable and the capacitor
bank.
