ARCTEQ INNOVATIONS

At Arcteq we design and manufacture the most accurate power grid protection in the world. We work hard every day to ensure that we are always one step ahead of our competitors.

We are proud to give you this brief look into our most essential innovations.

Intermittent Earth fault protection

Underground cabling makes distribution networks less vulnerable to disturbances, but also leads to higher earth fault currents and difficult intermittent earth faults. Read about Arcteqs patented solution for this.

Generator and Motor Commander

The generator and motor commander is a unique innovation combining machine protection and
control into one unit. The Commander is ideal for any power plant or industrial application where both
protection and control of generators or motors is needed.

Re-usable arc quenching device for medium
and low voltage

The quenching device extinguishes an occurred arc fault in as fast as 5 ms, by creating a low impedance path for the fault current. The quenching device absorbs up to 100 kA for 200 ms time.

The AQ 1000 quenching device for LV networks

Cable end differential protection

Compensated cable end differential protection
during a small earth-leakage current. Due to natural
unbalance compensation the function can alarm correctly even on extremely small differential currents.

Arcteq is the first protection relay manufacturer in the world to supply a protection relay with 0.2S measurement accuracy.

 

Disturbance recorder and
documenting power quality

The short story

The disturbance recorder in AQ 200 series IEDs is a high capacity and fully digital recorder integrated to protection relay. Maximum sample rate of the recorder analog channels is 64 samples per cycle. The memory capacity in AQ 200 series IEDs allows for up to 100 non-volatile records with total of 500 second recording time with full sample rate and maximum number of recorded channels.
