Introduction to Per Unit Systems

Learn about Per Unit System in Power Systems

To handle values in different units or with various representations is quite tough. To make the calculations easier and simplify the circuits, per unit representation is used. Did you explore about per unit representation of a power system’s model before? Do you know how to calculate per unit values? Have you ever realized the significance of a per unit system? What are the different advantages of a per unit system? How to change base values in per unit system? We have tried to explain all these basics with the help of examples in the best possible way here.

Protection Coordination Tutorial

Learn about Power system selective coordination

Selective coordination is the selection of protective device closest to the fault to open first and prevent the upstream devices from tripping. Do you know how protection coordination is achieved? What are the goals of protection coordination? Are you familiar with the definite and inverse time strategy? Have you ever heard of TCC curves? How TCC curves are helpful in achieving coordination among various protective devices? What are thermal magnetic breakers and electronic trip units? We deliver all these basics in descriptive way here.
