Differential Stability Anlyzer is the single free tool available on internet of its kind.Differential Stability Anlyzer is used to predict the effect of C.T.Ratio change , C.T.Ploarity change , Phase reversal , wrong Delta configuration ,Open circuit in differential circuit.It automatically calculate the HV current,LV current & Operating currents probably to be seen by the differential relay in realistic conditions.
During an unstable condition of Differential Protection of Power Transformer, we can simulate the possible causes by this software.We can save the current patterns for a different situations and can search a situation from the database in future by query.
It is a handon tool for Every Electrical/ Power Engineer / Student for studying the various factors which affects the Differential Protection Stability of Power Treansformer.It also includes module for Overcurrent/Earth fault settings.
Following conditions may be simulated by Differential Stability Anlyzer.
- Wrong Delta Connection.
- Wrong C.T. Ratio
- C.T. Polarity Reversal
- Phase Sequence Reversal in Differential circuit
*** IMPORTANT : "The software may only be used for education purpose only as www.epowersofts.com won't be responsible for any practical error/deviation of result values in field situations."

Differential Protection is used to protect the Generators & Transformers from internal faults.Differential Protection Relays are used to do so.Before the energisation of power transformer,it must be ensure that the connections doen for differential protection are in order.
Wrong connections/C.T. polarity may cause mal-function of Differential Protection Relays
Differential Stability Analyzer can simulate different abnormal conditions of differential circuits of a Yy0 group power transformer
