How-To: Calculate the Prospective Short-Circuit Current …

WebOct 2, 2024 · It means that the protective device that we will use must have a short circuit capacity of more than 20 KA. It will help the Over Current Protective device (OCPD) to safely interrupt this amount of fault current. This blog has just provided you a basic idea of how we will calculate the amount of short circuit current for a small power system. WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3).
