Hello, Thanks for your query. If I understood your question property, then this characteristics are derived using mathematical questions (generally inverse time equation), testing and all...It's provided bh manufacturers. Thus, when you solve the numericals, the data points always mentioned.
It's from the characteristics. Manufcature supplies the these characteristics which are derived using equations (but exact equations depends on type of relay), testing , calibration etc. The interpretation of time corresponding to PSM means that how relay reacts according to the severity of fault. If fault is more severe, relay trips quickly.
Mam your lecture is best and easy to understand!
Thank you🙂
Wonderful Lectures...Madam
Glad you like them!
Very good. Thanks 🙏🙏🙏🙏
Glad to know you liked it!
Man what is psm characteristics how it is come

Man how the time corresponding psm came
What it actual meaning
