Copper Losses

“How is electricity lost in copper?”
Current flow is one of the basis of operation for transformers. However, when the current will heat up the transformer, causing energy losses. These are known as Copper Losses and must be taken into account during transformer design.

“How does the electrical grid control power flow?”
The modern grid is becoming more and more digital than ever. To control everything going on, Energy Control Systems are used to monitor and dispatch loads when necessary.
Synchronous Compensators

“How can we use synchronous motors to stabilize the grid?”
Synchronous Motors are great for precision control applications. But their usage can be applied to grid stabilizations. Since voltage in a grid can fluctuate, by running synchronous motors at no-load speeds we can effectively have a load that adds inertia to the system, therefore mellowing out the voltage fluctuation. These devices are known as a Synchronous Compensators and are a vital part of the modern grid.
Synchronous Motors

“How can motors be synchronized with current?”
AC Motors can convert electrical energy supplied by current into mechanical energy. But are there motors where the frequency of the shaft’s rotation is equal to the frequency of the supply current? Well, it turns out these machines are known as Synchronous Motors and are used in cases where motor speed needs to be very precise.
