Are you tired of manually calculating Transformer Voltage Drop? Let’s enhance your knowledge, add some humor, and learn the formula in a code format.
V_d = KVA * (R_p * cos(theta) + X_p * sin(theta))
Where V_d is the Voltage Drop in Volts, KVA is the apparent power in Kilo Volt-Amperes, R_p is the resistance in Ohms, X_p is the reactance in Ohms, and theta is the phase angle between voltage and current.
