New EMTP version 4.0

Highlights
  • EMTP 4.0 contains many improvements on several fronts.
  • The GUI EMTPWorks now allows to draw diagonal signals (at any angle) and offers new line editing features. This will simplify the drawing tasks for large scale transmission and distribution grids.
  • The new View Steady-State tool offers many new load-flow and steady-state visualization options.
  • The new Wideband transmission line and cable model with its new fitter is a major milestone. It delivers the most stable and accurate model in the industry for switching and lightning transients. It also delivers higher accuracy for DC cables in HVDC transmission.
  • The new TRV breaker contains the TRV standards in its mask and simplifies engineering tasks for TRV simulation and analysis.
  • The new line differential relay allows protection engineers to setup and test line relays to avoid spurious tripping during line energizations, current transformer saturation, etc.
List of new features
  • Line Styles – allows signal lines to be displayed with a variety of bold colours and patterns to highlight function or status
  • Diagonal Lines and Line editing features – allows more flexibility in signal line drawing
  • Unicode String Format – EMTPWorks can now be adapted to any international language so users can display notations in their own language and use many special symbols
  • Many new customization features, script methods
  • New View Steady-State tool: shows sequence currents and phase currents, automatic subnetwork view, new reporting features
  • Changes and improvements in devices (upgrades in data input)
  • Better support of high resolution screens, including 4K

  1. New TRVbreaker: TRV studies made easy!

The new breaker for TRV helps engineers to interpret their TRV simulation results.

It draws on the same graph the system prospective TRV obtain by EMTP simulations with the circuit-breaker rated TRV obtain from IEC 62-271-100-2008 and IEEE C37.006-2008 standards.

Without any efforts, engineers can complete the full TRV analysis without having to interpret the circuit-breaker standards.

  1. New line differential relay model

The new line differential relay allows protection engineers to accurately verify their relay settings toward challenging scenarios like line energization or current transformer (CT) saturation.

They even have the option to display the Alpha Plane to verify the restraint.
