The PGC5000 analyzer “must be so designed and

constructed as to prevent ignition sources arising,

even in the event of frequently occurring

disturbances or equipment operating faults, which

normally have to be taken into account”. The design

of the analyzer is capable of functioning within the

established operational parameters and of ensuring

a high level of protection necessary for the intended

classified Ex zone 1 area.

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.
