AdvaSense

Medium voltage AdvaSense indoor sensors offer an advanced solution for measurement, protection and control of the medium voltage distribution network.

Towards a smarter and more resource-efficient future 

 

Medium voltage indoor sensors, also called Low-power Instrument Transformers (LPITs), are based on alternative principles (Rogowski coils or voltage dividers) and can successfully replace conventional instrument transformers significantly reducing size, increasing safety, while providing greater rating standardization and a wider functionality range. These well-known principles can only be fully utilized in combination with versatile Intelligent Electronic Devices (IEDs), such as protection and control relays among others.  

ABB’s main product line for medium voltage indoor sensors is called AdvaSense. ABB’s medium voltage AdvaSense indoor sensors, for IEC standards, up to 48 kV, are designed for a wide dynamic range of input parameters. Under ABB’s AdvaSense product line, we offer several types of indoors sensors: 

  • Indoor current sensors for primary and secondary air- and gas-insulated medium voltage switchgear, up to 4000 A, for current measurements with high linearity and wide dynamic range, based on the principle of Rogowski coil.
  • Indoor voltage sensors for primary and secondary air- and gas-insulated medium voltage switchgear, up to 48 kV, for voltage measurements with high linearity and wide dynamic range, based on the principle of voltage divider.
  • Indoor combined sensors and sensors for special applications, up to 40.5 kV, for current and voltage measurements as well as voltage indication integrated in the same compact cast resin part, based on the principle of Rogowski coil and voltage divider.

To provide connectivity between sensors and IEDs with different types of connectors, ABB designed a group of accessories. Beyond the connectivity, accessories also offer special protection schemes with sensors. 

 

Built to withstand the rigors of the most demanding environments, ABB medium voltage indoor sensors are available for original equipment manufacturers (OEMs), panel builders and non-panel builders’ applications, Engineering, Procurement and Construction (EPC) partners, utilities, as well as end-users to incorporate in their own installations. 

ABB supports customers and partners in staying ahead of increasing electrification needs, technology, and regulatory changes, providing the power to adapt to a rapidly evolving energy landscape.

Sensor accessories

To provide connectivity between sensors and intelligent electronic devices (IEDs), such as protection and control relays, with different types of connectors, ABB designed a group of accessories. The purpose of the connector adapters is to adapt the sensor connector type to the IED connector type if they do not match directly. Beyond the connectivity, accessories also offer special protection schemes with sensors.
