Time Dial Setting Cross-Reference
Although the time characteristic curve shapes have been optimized for each BE1-11m, time dial settings
of Basler Electric protection systems are not identical to the settings of electromechanical induction disk
overcurrent relays. Table 82-3 helps you convert the time dial settings of induction disk relays to the
equivalent setting for Basler Electric protection systems. Enter time dial settings using BESTCOMSPlus.
For more information, refer to the Inverse Overcurrent (51) Protection chapter.
Using Table 82-3
Cross-reference table values were obtained by inspection of published electromechanical time current
characteristic curves. The time delay for a current of five times tap was entered into the time dial
calculator function for each time dial setting. The equivalent Basler Electric time dial setting was then
entered into the cross-reference table.
If your electromechanical relay time dial setting is between the values provided in the table, it will be
necessary to estimate the correct intermediate value between the electromechanical setting and the
Basler Electric setting.
