What will happen if voltage applied is more than rated voltage of transformer?

As the higher voltage gives a higher current (Ohms Law). the current on the primary does increase, so the power (voltage * current) will be much higher, and the transformer will overheat and burn out.

What happens if you apply too much voltage to a motor?

The overvoltage can cause excessive current to flow as well as creating excessive voltage stresses. In both cases, the electrical insulation system inside the motor or equipment can be degraded reducing life or causing damage.

What is the effect of over voltage?

EFFECTS OF OVER VOLTAGES ON POWER SYSTEMS damage to them when it frequently occurs. Over voltage caused by surges can result in spark over and flash over between phase and ground at the weakest point in the network, breakdown of gaseous/solid/ liquid insulation, failure of transformers and rotating machines.

What will happen if power rating of a device is exceeded when operating under normal conditions?

Exceeding the power rating of a device by more than the margin of safety set by the manufacturer usually does damage to the device by causing its operating temperature to exceed safe levels.

What happens if voltage is too high on a component?

Exceeding Input Voltage Limits – Component Failures Component failures occur when a component is damaged and/or no longer operates as intended. Applying a voltage that exceeds a component’s maximum operating voltage is a simple way to damage any component.

What is the difference between primary and secondary voltage of transformer?

The no-load voltage(referred to the primary) of the transformer is the primary voltage. As the load increases to full load, current flows in the windings of the transformer and there is a voltage drop across the transformer, and the referred value of the secondary voltage is no longer equal to the primary voltage.

What happens if voltage is too low on a power supply?

When operating a power supply below the minimum operating voltage, the current in many components will increase proportionally. The fuse, rectifier, switches, and other components that carry this increased current will all dissipate more power, leading to an increased temperature and chance of failure.

Why does a boost converter not work with power factor correction?

In the case of a boost converter, it only outputs a voltage higher than the input voltage. If an ac-dc power supply with power factor correction is operated with an input voltage greater than the output of the boost converter voltage, the boost converter will not work and fail to correct the power factor.
