Several different real-time simulation hardware manufacturers can be found on the market. However, RTDS from Canada ( is a leading company in this field, as their simulators are of modular design and exceptional characteristics, which results in several references from all over the world. Real-time simulation requires extremely short integration time-step and RTDS simulator can reach even as low as 50 μs (for small-time-step modelling even 1.5 μs). Simulator is applicable on many different fields, especially for equipment close-loop testing, such as protection relays and different control systems.
