Calculation of setting values ​​for distribution network relay protection

Calculation of setting values ​​for distribution network relay protection

This calculator performs basic distribution system protection calculations, including base current, secondary current, plug setting multiplier, and relay operating time. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. Calculation Example: This calculator helps in determining the settings and operating time of overcurrent relays in a distribution. This technical report refers to the electrical protections of all 132kV switchgear. [pdf]
