BE1-11t, Transformer Protection System

* Optional

• Entering protection settings with confidence is easy with BESTCOMSPlus® software that provides intuitive settings with graphs, built-in error checking, and summary screens.
• Complex protection is easy to configure and understand with preprogrammed schemes, drag-and-drop logic, user labels, and notes provided by BESTlogic™Plus.
• The Offline Simulator in BESTlogic™Plus helps identify and troubleshoot the logic without the need for expensive physical hardware.
• Adaptable coordination for difficult applications is made possible by 24 industry-standard timing curves and five user-defined curves.
• More efficient maintenance scheduling is possible by using through-fault counter data.
• Meet your modern communications needs with 10/100Mbit copper or 100Mbit fiber-optic Ethernet with IEC 61850, DNP, or Modbus®.
• Connection is easy, even when using multiple large wires, with large screw terminals for all terminations.
• Get the information you need for system analysis with distance-to-fault, oscillography, demand metering, power quality, breaker monitoring, and other data provided by the BE1-11.
• Increased security and selectivity provided with differential protection.
• Provides more accurate detection of inrush current on modern transformers by using shared harmonic blocking.
• Easily navigate settings and metering with the intuitive Human Machine Interface (HMI) menu and large LCD display.
• Customize displayed information to meet different application needs with user-definable indicators and labels.
• Direct control of internal logic using Select and Operate buttons available on the front panel.
• Reliable protection even during abnormal operation events such as high ambient temperature, or blocked cooling with the optional RTD module.
• Optional RTD module with fully configurable analog outputs can be used to drive analog meters. Easily assigned trip points can be scaled by the user to reflect measured parameters.
• Up to 14 combined alarm and trip temperature monitoring points are possible using an optional RTD module.
• Reduce installation costs and improve reliability by mounting an optional RTD module near the point of measurement to minimize cable lengths.
