Why Gridscale X Advanced Protection Assessment?

Protection engineers face a growing set of challenges as power systems become more complex. Digitalization, rising volumes of protection data from relays and substations, pressure to improve grid reliability, and increasing regulatory demands all add to their workload. Advanced Protection Assessment (formerly PSS®CAPE) supports engineers in transmission and large distribution utilities, as well as some generation owners, across their entire protection workflow - from detailed data collection and electronic setting management to setting calculations and validation.

With its extensive library of high‑fidelity relay models and modular protection tools, it enables engineers to efficiently manage large, complex network datasets, detect potential issues early, and evaluate alternative solutions.

Key benefits

Optimize grid operations with an integrated solution

Complete analysis and simulation to solve data management issues, uncover potential network and protective device problems, and evaluate alternatives.

Gain market-leading capabilities

Run simulations on networks of any size ranging from under 100 buses to 10,000 buses – including protection systems with 20,000 to 50,000 relays or more.

Perform regulatory compliance studies

Setup, save and store study parameters in Advanced Protection Assessment to be able to rerun the same compliant study in the future, compare study results over time and document results to prepare compliance reports.
