“How can we control the moisture in a transformer?”

 

Transformers are some of the most fundamental pieces of critical infrastructure. However, they can also be quite delicate. If there is too much moisture near the insulating material, it can induce a fault. So how can we use our engineering mindset to solve this problem? Well, what if we were to attach a cylindrical filter filled with silica gel at the entrance of the transformer so that any air that passes through will have its moisture taken out? Well, this is known as a Transformer Breather and is vital for transformer operations.

“How can we cool the oil in a transformer?”

 

Transformer oil is vital for winding insulation. However, in order for optimal performance, it must be kept at a cool temperature. So how can we use our engineering mindset to accomplish this? Well, what if we were to simply have the transformer oil circulate in tubes near a cooling source? This is the idea behind Transformer Cooling Tubes and is a staple of transformers in the world.

“Can energy become so cheap that prices become negative?”

 

The more supply relative to demand that cheaper a product is. And energy is no exception to the rule. States such as Germany, California, and Hawaii are now generating so much energy from Distributed Energy Resources and conventional power during low period times that electricity prices are going negative! To avoid great imbalances, these areas are now selling their energy to neighboring states to create grid balance.

“How can we reject transformer oil in the case of a fault?”

 

Transformer oil is vital for maintaining electrical insulation. However, sometimes a transformer fault can occur and overheat the system. So how can we use our engineering mindset to prevent drastic damage? Well, we can simply build an Explosion Vent in the system. When an explosion occurs in the system, transformer oil will rush out and be ejected safely.

“How can we control a transformer’s temperature?”

 

A transformer fault from overheating can rupture an entire distribution grid. So how can we use our engineering mindset to prevent this? Well, how about we take a note from other cooling systems and run a coolant around the wires and core and reject the heat to the ambient space? This is the fundamental idea behind Transformer Cooling which saves tons of transformers each year.

“Is oil used to insulate transformers?”

 

Transformers are an inseparable part of Critical Grid Infrastructure. And part of their day-to-day functioning requires insulation material. However, such material will have to be able to withstand high temperatures and sudden electric discharges. This is commonly solved using Transformer Oil, a substance employed all around the world.

“How can we use insulators to make a transformer function?”

 

Transformers are made by applying a voltage in one pair of wires to induce a secondary voltage in another. However, these two wires must never interfere with each other, since it could cause a rupture in the system. To prevent this, we can use Insulating Materials in a Transformer that prevents such contact from taking place.

“What keeps the winding in a transformer together?”

 

Electrical winding makes up the very core of a transformer. Or so it is thought. The actual Transformer Cores are the support structure for the metal windings. Not only this, but it provides reluctance to magnetic flux and prevents the spread of eddy current and hysteresis loss. The core’s diameter size is proportional to copper loss and inversely proportional to iron loss.
