Relay Protection CT Saturation Issue
Relay Settings Consideration 🏭 Factory Experience: X/R Ratio Matters: In systems with X/R > 15, always use gapped core or TPY class CTs. The DC component will saturate conventional CTs within one cycle. Commissioning Check: After installation, perform excitation tests on. describe how CTs saturate in a simple and intuitive way. We then describe the CT equivalent circu t and how it results in the familiar CT excitation graph. ANSI ratings of. Current Transformers (CTs) are critical components in power systems, used to step down high currents to safe levels for protection relays, meters, and monitoring devices. While CTs are generally reliable, they can experience saturation, which leads to inaccurate measurements and potential. CT saturation occurs when the magnetic core of a current transformer reaches its magnetic limit & cannot respond linearly to increasing primary current. However when the magnetic flux exceeds the. point). Beyond this point, increases in primary current produce little or no increase in secondary current.
