IEC 61660 Standard

Benefits of using IEC 61660 / Benefits / IEC 61660 in ETAP - Benefits

• Accelerate Efficiency
  • Adhering to the IEC 61660 standard involves using element models with non-linear characteristics and an iterative solution process. Calculating multiple faults in large scale systems with common branch scenarios is a time intensive solution. Using ETAP to perform short-circuit analysis complying with the IEC 61660 standard allows users to advance past the calculation process and analyze the results instantaneously, this includes viewing result annotations, comprehensive reports, and plots.
• AC/DC Interconnectivity
  • ETAP allows users to interweave AC and DC systems together for a robust analysis with elements such as Charger (Rectifier), UPS, and Inverter. The Charger (Rectifier) element, modeled in accordance with IEC 61660 takes into account AC fault contributions and AC system impedance in order to solve for DC system faults
• Fault Analysis
  • There are many aspects to a successful short-circuit analysis such as device duty evaluation and protective device coordination. Using ETAP with the IEC 61660 standard facilitates users to perform device duty evaluations based on the peak short-circuit contributions as well as the quasi steady-state results. Users also have the option to perform a device duty evaluation using the total bus fault current or based on maximum through fault current.
