Benefits that add value

Get a drive solution that meets the requirements of your application and

ensures high productivity and the optimum performance of your operations.

Benefit from the built-in expertise of our medium voltage drives and take

your business forward with everything working like clockwork.

The S100 I/O process interface modules for Advant Controller 400 series process controllers come with connection units,

simplifying cable termination and keeping noise and destructive spikes away from the central electronics.

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.
