Special Case Study
AIT also offers special case studies for our clients with regards to
power system analysis and faults studies.
The extend of our capabilities as follows:
1. Power System Fault Studies
accurate fault studies to provide the data needed to specify substation
equipment, size switchgear, and set protective relays.
When you need
fault study results, AIT can deliver, either alone, or as part of a
larger project. For applications involving three-phase and complex
network, AIT uses Electromagnetic Transient Program (ATP/EMTP) to
simulate the required conditions.
2. Digital Simulations
ATP is a universal
program system for digital simulation of transient phenomena of
electromagnetic as well as electromechanical nature. ATP-EMTP is used
world-wide for switching and lightning surge analysis, insulation
coordination and shaft torsional oscillation studies, protective relay
modeling, harmonic and power quality studies, HVDC and FACTS modeling.
Typical EMTP studies carried out by AIT are:
Evaluation of Relay Protection Schemes
Lightning overvoltage studies
Switching transients and faults
CVT Transient Response
Transient stability, motor startup
Transformer and shunt reactor/capacitor switching
Transmission Line Switching
Circuit breaker duty (electric arc), current chopping
Protective Device Testing
