Minimise system forced outages and relay mal-operations resulting from setting design and application errors. The protection system analysis/design undertaken by Applied Power Technologies uses sophisticated network and protection system models. Network models employ detailed bus configurations to facilitate the accurate placement and summation of measurement transducers supplying protection devices. Detailed relay specific models of the main and supervisory elements capture the manufacturer’s comparator equations, internal logical functions and actual tap settings. External scheme logic, typically composed of permissive/blocking signals and intertrips, completes the mathematical representation. The analysis undertaken using these network and protection models reflect the exact behaviour of the relay in the field. The response in steady state or time domain simulations, informs you on how your installed protection will respond to disturbances. Contact us for more information on how we can help.
