ABB VIPA972-0DP01 Profibus-DP bus connector

Protection functions

The IED offers directional and non-directional overcurrent and thermal overload protection as

well as directional and non-directional earth-fault protection. 

Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be

used in addition to directional earth-fault protection. 

Further, the IED features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, 

overvoltage and undervoltage protection, residual overvoltage protection, positive-sequence undervoltage 

and negativesequence overvoltage protection. 

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.

Frequency protection, including overfrequency, underfrequency and frequency rate-of-change protection,

is offered in IEDs with standard configurations H and J. 

The IED also incorporates optional three-pole multi-shot auto-reclose functions for overhead line feeders.

Enhanced with optional hardware and software,the IED also features three light detection channels 

for arc fault protection of the circuit breaker, busbar and cable compartment of metalenclosed 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.
