What is a transformer explosion?
Figure 1-1 explosion of transformer
A transformer explosion is a catastrophic accident that occurs when a transformer is in operation due to internal influences or external influences. In a explosion of transformer, the electrical energy built up inside the transformer is rapidly released, usually accompanied by a loud bang or a series of explosions. This release of energy causes structural damage to the transformer, with transformer fragments flying in all directions. The intense heat generated may start a fire. Further exacerbating the situation and posing a significant threat to buildings, infrastructure, and personnel in the surrounding area. Transformer blowing up can cause a very large amount of economic damage.

We as electrical industry practitioners, we all have a great curiosity about the causes of exploded transformer, what actually causes the transformer blew up? what makes a transformer blow?
Next, we will show real cases in shinenergy practice to reveal the causes of transformer blowing at night for you one by one:
How does a transformer blow? Internal factors leading to transformer exploding:

Overloading causes the transformer to explode
The customer of shinenergy, which is involved in photovoltaic power generation, placed an order for a transformer with a rated capacity of 1,000kVA to convert the DC power generated by the solar panels into AC power and transmit it to the grid.
Initially, the power station was designed for an installed capacity of 800kW and the transformer was working fine. The maintenance team inspected the transformer electric components to ensure there were no signs of wear that could lead to a power outage. However, the power station decided to expand and upgrade the capacity by adding more solar panels, bringing the total installed capacity to 1,200 kW. During the expansion, the transformer was overloaded for a long period of time.
The transformer, which was originally rated at 1000kVA, had to carry a load of 1200kW for a long period of time. The load on the transformer was continuously high. After several months of continuous operation, a slight burning odor could already be detected in the vicinity of the transformer.
This indicates that the insulation inside the blown transformer fuse blown may have been damaged to some extent. Eventually, the insulation of the transformer was severely degraded, leading to a partial short circuit fault where the transformer fire into flames, which was fortunately detected in time without too much damage. After the transformers blast off, emergency services were on high alert, quickly responding to the scene.

Insulation failure leads to transformer blows up
why would a transformer blow? As we learned in the real-life example above, when a transformer is overloaded causing the temperature of the transformer’s operating environment to exceed its designed temperature rise range, the transformer’s insulating paper can burn and become damaged. Therefore, insulation within the transformer is critical to prevent arcing between different transformer components. Over time, the insulation may deteriorate due to factors such as damage, aging, moisture intrusion or chemical exposure. Once the insulation fails, arcing can occur, generating intense heat and potentially leading to blowing transformer.

Manufacturing defects cause transformers blowing up
what makes transformers blow? Sometimes transformers produced by some irresponsible manufacturers may have inherent manufacturing defects that can affect their performance and reliability. These defects may include faulty winding connections, substandard insulation or improper assembly, all of which increase the risk of trafo explosion.

Power surges cause exploding electrical transformer
what does it mean when a transformer blows?Voltage surges in the grid, whether from lightning or other sources, can place excessive stress on the insulation and components of a transformer, leading to a potential exploding electrical transformer.
External factors leading to electric transformer explosions:
Lightning strikes cause current transformer explosions:
why do power transformers blow? Substations are often vulnerable to lightning strikes. A direct hit or a nearby lightning strike can generate very high voltages and currents in a transformer, overwhelming its protection system and causing fusing.
Short circuits cause transformers to explode:
Figure 1-7 why do transformers blow
why do electrical transformers blow up? Internal or external short circuits can cause large amounts of current to flow through a transformers blowing up The sudden increase in current generates excessive heat, damaging the windings and causing fusing.
Other external factors cause transformers to explode:
Figure 1-8 electrical transformer explosion
what causes a transformer to blow up? Things such as vibration, mechanical stress or poor maintenance can also cause transformers to fail. For example, vibrations from nearby machinery or transport can loosen connections and cause internal damage over time, leading to electrical transformer explosion.

How can we prevent transformer explosions?
Figure 6-1
To prevent transformer exploded, we’ve got to approach it from a few different angles. Regular maintenance is crucial, just like changing the oil in your car. It keeps everything running smoothly and catches potential issues before they become big problems. We also need to monitor the load on transformers to avoid overloading them. It’s like not asking your car to pull a load it’s not designed for. Keeping the temperature in check is another important aspect. Overheating can cause the insulation to break down, leading to short circuits and potential transformers explosions, much like how an engine can seize up if it gets too hot.
High-quality insulation is a must, as it can handle higher voltages and reduce the risk of short circuits. When it comes to weather, especially thunderstorms, we should have lightning protection to safeguard transformers from being struck. Short-circuit protection is also essential. It’s like having a parachute in case something goes wrong, allowing the transformer to cut power quickly and avoid a catastrophic failure. The liner power transformer’s efficiency has been improved with the latest cooling technology, reducing the risk of overheating.
Purchasing transformers from reputable manufacturers is key. It’s not the place to cut corners. We also need to ensure transformers are in environments that won’t cause them to corrode or degrade, similar to how you wouldn’t leave a car out in the elements without protection. Proper training for those who operate and maintain transformers is non-negotiable. It’s like ensuring your mechanic knows how to fix your car correctly.

It can take anywhere from a few hours to several days or even longer in some cases.
Why do transformers blow during storms?
- Lightning Strikes: Direct hits or nearby strikes can cause extreme voltage surges that exceed the transformer’s insulation capabilities, leading to explosions.
- High Winds and Debris: Strong winds can knock down trees or other objects that crash into transformers or power lines. It causes short circuits or physical damage that may lead to a transformer blowing.
- Flooding: Water can cause electrical shorts and damage the transformer’s insulation, leading to failures.
- Overload: Storms can lead to increased demand for electricity for heating or cooling. Which can overload transformers if they are not designed to handle the extra load
