Connected current sensing unit puts teams on alert for quick fault fixing

ABB’s easy-to-use Software-as-a-Service solution adds remote monitoring of CSU-2 current sensing unit to options for facilities – delivering instant arc incident alerts and highlighting root causes faster


ABB has extended the capabilities of the ABB Ability™ Energy and Asset Manager now integrating data from the CSU-2 current sensing unit. This latest addition to the cloud platform gives facility control centers complete visibility of their low- and medium-voltage switchgear, assets and system status in one place.

The addition will be of particular benefit to ships and marine applications, data centers and process industries such as steel and paper manufacturing where distribution systems are complex and electrical loads can vary significantly.

Andrea Temporiti, Head of Digital at ABB Electrification, said: “The breadth and depth of ABB’s digital ecosystem is industry-leading. By integrating CSU-2 current sensing units into the ABB Ability™ Energy and Asset Manager, customers have real time data and remote monitoring of their distribution panels. No other hardware is needed, – just this simple device – demonstrating ABB’s commitment to making digital energy and asset management more accessible for everybody.”

Part of the ABB Arc Guard SystemTM, the CSU-2 current sensing unit makes arc flash protection systems more precise, easier to monitor and control. For facilities with complex distribution systems or load variations, the CSU-2 provides an additional layer of protection against downtime for main- and sub-distribution switchboards.

The CSU-2 can continuously monitor the three phases used in industrial power applications, as well as the neutral current used for safety and load balancing – and feeds the data to the ABB Ability™ Energy and Asset Manager. With cloud monitoring of the device and its diagnostics, operators receive instant digital alerts when situations require a swift response, identifying arc incidents sooner, minimizing downtime and improving operational performance.

Analyzing the complete switchgear also makes it easier to identify the root cause of any incidents. With all events logged by theABB Ability™ Energy and Asset Manager, analysis of old events and identification of future improvements for the switchgear becomes effortless.

The CSU-2 sends data to the cloud using the secure Modbus RTU communication protocol.  ABB Ability™ Energy and Asset Manager is a state-of-the-art cloud solution that integrates all the energy and asset data into a single, intuitive dashboard. The Software-as-a-Service (SaaS) solution gives users flexibility, adding or removing subscription-based services as needed, to help users minimize cost and risk, while maximizing safety and performance across their operations.
