Frequently Asked Questions

1. Can transformers be operated at voltages other than the prescribed voltages?

Transformers can sometimes be used at voltages that are lower than the rated voltage. However the voltage rating of a transformer should NEVER be exceeded unless taps are provided for this reason. Note, when operating below the rated voltage the KVA capacity is reduced correspondingly.

2. What is meant by impedance in transformers?

Impedance is the transformer’s ability to restrict current and is expressed in percentage.

3. What does a transformer rating mean?

The rating of a transformer is the maximum power which can be drawn from it without the temperature rise in the winding to go over what is considered safe for the specific kind of insulation used.

Frequently Asked Questions

1. How often should transformers be inspected and serviced?

The amount of use and the surroundings where the transformer is stored, determines how frequently it needs maintenance. The best environment for a transformer is one that is dry and clean; in this setting, the unit just needs annual inspections and maintenance. However, transformers kept under environmental conditions where the air is contaminated by substances like chemical fumes or dust, will need more frequent (every 3-6 months) inspections.

2. What is the difference between a power transformer and an instrument transformer?

A power transformer is primarily used in power transmission and distribution to either step up or step down a voltage level. While an instrument transformer is used in a circuit for the measurement of voltage or current.

?3. How much would a new transformer save?

Since transformer technology has advanced dramatically over time, there are more benefits to upgrading an outdated transformer. An old transformer may have an average energy efficiency rating of 85%, which means 15% of the energy is wasted. The energy efficiency of a contemporary low loss transformer can reach 99.75%.

Frequently Asked Questions?

1. Why is the transformer used in kVA?

Transformers are used and rated in kVA, to account for power losses. The total heat losses in a transformer depends on volt-ampere (VA) only and not on the power factor of the load. That is why the transformer rating is given in kVA and not in kW.

2. How much is 1 kVA in Watts?

1 kVA is equal to 1 kW. That means that 1 kVA is equal to 1,000 watts. So to determine your transformers rating in watts, multiply the transformer’s kVA power rating by 1000.

3. Why do transformers hum?

The repetitive expansion and contraction of the steel core inside the transformer is what causes transformer hum or noise. The expansion of the core depends on the amount of flux passing through it, which in turn depends on the applied voltage and the number of turns of transformer coils.

Frequently Asked Questions

?1. What does a transformer rating mean?

The rating of a transformer is the maximum power which can be drawn from it without the temperature rise in the winding to go over what is considered safe for the specific kind of insulation used.?

?2. Can transformers be operated at voltages other than the prescribed voltages?

Transformers can sometimes be used at voltages that are lower than the rated voltage. However the voltage rating of a transformer should NEVER be exceeded unless taps are provided for this reason. Note, when operating below the rated voltage the KVA capacity is reduced correspondingly.

3. How much would a new transformer save?

Since transformer technology has advanced dramatically over time, there are more benefits to upgrading an outdated transformer. An old transformer may have an average energy efficiency rating of 85%, which means 15% of the energy is wasted. The energy efficiency of a contemporary low loss transformer can reach 99.75%.?
