Products»EuroProt+»DAUT» E3-HSBT High Speed Bus Transfer device
Overview
HSBT
The E3-HSBT is a control IED made for realizing high speed bus transfer for busbar sections supplying induction machine load; the device provides solution for bus transfer applications where quickness might be a crucial factor even to a point of a live bus transfer. It is a member of the DAUT product type in the EuroProt+ product family. The EuroProt+ family complex protection in respect of hardware and software is a modular device. Because of the modular architecture, the modules are assembled and configured according to the user’s requirements; from that point on, the software determines the functions.

Devices of the DAUT product type are configured for various automation purposes of the electric power system.

The EuroCAP configuration tool, which is available free of charge, offers a user-friendly and flexible application for protection, control and measurement functions to ensure that the IED-EP+ devices are fully customisable.

Application
HSBT
Power energy availability is crucial for providing reliable power production for essential processes in power stations and industrial plants where lots ofinduction motors are applied. The E3-HSBT devices are designed to perform automatic high speed switching to a back-up power supply if the main feeder gets tripped.

In addition, the function takes into consideration the changing voltage and frequency of high power induction motors operating on the unsupplied busbar by controlling the moment of switching in order to avoid high current surges and mechanical stress for the rotating machines.

The IED includes wide range of control and supervisory functions which provide full control and user defined interlocking schemes for the primary switchgear at the substation.

SCOPE OF APPLICATION

  • Provide reliable, safe and uninterrupted supply
  • Support for simple and complex busbar applications (one HSBT function for each CB)
  • Guarantee of the shortest possible high speed switching time and the highest possible level of safety
  • Guarantee of an optimum safeguarding of energy supply
  • Instantaneous/Fast/Slow operation according to amplitude, frequency, angle, df/dt conditions, status signals and parameters.
  • The switching-over can be initiated automatically or manually as well
Protection & Control functions
The E3-HSBT configuration measures three-phase voltages from each side of the handled circuit breakers. The main function is the High Speed Bus Transfer function - the configuration contains as many instances of it as many CBs there are to transfer between. Each configuration is unique according to the actual bus arrangement which may vary largely but still can be handled thanks to the highly configurable logic of the device.

Protection & control functions IEC ANSI *Inst.
High Speed Bus Transfer 83 3
*The INST. column contains the numbers of the pre-configured function blocks in the factory configuration.These numbers may be different in order to meet the user’s requirements.
