What Happens When Transformers Fail

TRANSFORMER: A transformer is an electrical device that transfers electricity between two or more circuits via electromagnetic induction and consisting of  two or more coils.

• Its network is based on two ports.
• Its not an energy conversion device.
• It follows Faraday's laws of Electromagnetic Induction.
• A transformer converts high-voltage electricity into 120 volts that is usable in daily households.

  FACTORS OF FAILURE According to National Fire Protection Association (NFPA) there might be several factors that can trigger a transformer failure:

• The sudden surge when they’re burdened with more energy than their capacity.
• Lightning strikes can also cause the transformers to overload, resulting in an explosion.
• A faulty wire may also be a reason.
• The mineral oil that is used as a cooling agent may caught fire due to the melting of circuits which occurs as a result of overload.

EFFECTS OF FAILURE Modern Electrical Safety Courses warn us several dangers that might arise due to a failing transformer, which are as follows:

• SHOCK

When electricity passes through the body for short period of time and only causes minor injuries.

• ELECTROCUTION

When electricity passes through the body for relatively delayed time period and result in serious injuries such as Involuntary Muscle Contraction, and other internal injuries, or even death.

• ARC FLASH

An exothermic reaction due to a faulty wire or overload that causes significant surge in temperature, resulting in sparks that may cause the transformer to catch fire and explode.
