Abb high voltage ring main unit energy storage

How ABB responds to the increasing demand for ring main units?

The increasing demand for reliability and effectivness of distribution networks requires higher flexibility and more automated ring main units. As one of the biggest player in the medium voltage distribution segment, ABB replies to this demand by installation of grid automation devices.

What makes ABB safeplus unique?

The current ABB SafePlus range satisfies the most complex system specifications. The most unique specialization is the development of the cable ring switchgear. The numerous public distribution substations requested a unified switching functionality which evolved into the ring main unit concept.

What is the difference between ABB safering and ABB safeplus?

ABB SafePlus offers more in terms of flexibility and electrical capacity. Both switchgear offer the same customer interface. The applied functionality in ABB SafeRing and SafePlus is a result of input from customers all over the world. Key customers are continuously involved with ABB design staff to ensure optimized switchgear operation.

What are ABB safety interlocks?

ABB safety interlocks enable the highest level of reliability, even in the case of an accidental error, and ensure operator safety. The use of key interlocks is very important in realizing the interlocking logics between panels of the same switchgear, or of other medium, low and high voltage switchgear.

Which metering module is available for ring main unit?

• Solution is available for 3-or 4-way units for 12 and 24 kV. The measurement has to be taken from the right-hand side. No need for separate metering module in typical ring main unit applications with one incoming/ outgoing feeder. Integrated voltage and current transformers used for tariff metering. CTs Class 0.2 S

What GIS solutions does ABB offer?

ABB offers two GIS solutions: the ZX line rated up to 40 kA/5000 A and the SafePlus line up to 25 kA/600 A (ring main units). Both solutions offer a minimum 30-year lifespan with gas leakage rates of less than 0.1% per year.
