Explanation of several of the terms used in the tablets (in alphabetical order)
I0H: Zero variation of Io after overloading with a DC of tenfold the rated value (RM = RMN)
I0t: Long term drift of Io after 100 temperature cycles in the range -40 bis 85 °C.
tr: Response time (describe the dynamic performance for the specified measurement range), measured as delay time
at IP = 0,9 . IPmax between a rectangular current and the output current.
∆t (IPmax): Delay time (describe the dynamic performance for the rapid current pulse rate e.g short circuit current)
measured between IPmax and the output current ia with a primary current rise of di1/dt = 100 A/µs.
UPD Rated discharge voltage (recurring peak voltage separated by the insulation) proved with a sinusoidal voltage Ve
UPD = √2 * Ve / 1,5
V
vor Defined voltage is the RMS valve of a sinusoidal voltage with peak value of 1,875 * UPD required for partial discharge
test in IEC 61800-5-1
V
vor = 1,875 *UPD / √2
V
sys System voltage RMS value of rated voltage according to IEC 61800-5-1
V
work Working voltage voltage according to IEC 61800-5-1 which occurs by design in a circuit or across insulation
