DPR-350 User Manual Ver_01 Firmware V-1.0

The DPR-350 controller offers constant time and 12 different variable time curves for protection functions.

Current / time curves are usually calculated using the equation below:

Here :

t(I) = Trip time as a function of input current I

I = Instantaneous secondary current value of the phase

Is = Fault threshold for secondary current

T = Time coefficient (TD for IEEE, TMS for IEC)
β = Constant for the given curve
α = Constant for the given curve
L = Constant for IEEE, 0 for IEC

C = Constant additional delay
