Difference Between Power Transformer and Distribution Transformer

Whereas power transformer is designed for maximum efficiency at 100% load as it always runs at 100% load being near to generating station. Distribution Transformer is used at the distribution level where voltages tend to be lower . The secondary voltage is almost always the voltage delivered to the end consumer.

What are the 3 types of transformers?

There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical. The electromagnetic voltage transformer is a wire-wound transformer. The capacitor voltage transformer uses a capacitance potential divider and is used at higher voltages due to a lower cost than an electromagnetic VT.

What is the difference between power transformer and distribution transformer in core losses and copper losses?

In Power Transformer, the iron and copper losses take place throughout the day but in distribution transformer, the iron loss takes place 24 hours i.e., throughout the day, and the copper losses depend on the load cycle.

What is the use of distribution transformer?

A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.

What is the difference between 33kV and 11kV?

The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.

What are the two main types of transformer?

There are two types of potential transformers; the conventional wound type (or electromagnetic type) and the capacitor voltage (potential) transformer.

Who is the main transformer?

The Autobots (also known as Cybertrons in Japan) are the heroes in the Transformers toyline and related spin-off comics and cartoons. Their main leader is Optimus Prime, but other "Primes" have also commanded the Autobots such as Rodimus Prime. They are constantly at war with the Decepticons.

Which transformer is used in distribution?

In electrical, step down transformers are used in electrical distribution system which works on very high voltage to ensure low loss and cost-effective solution for long distance power delivery requirements. To convert the high voltage to a low voltage supply line, Step down transformer is used.

What are the functions of no load current in a transformer?

While primary winding carries a small current I₀ called no-load current which is 2 to 10% of the rated current. This current is responsible for supplying the iron losses (hysteresis and eddy current losses) in the core and a very small amount of copper losses in the primary winding.

What is the transformer efficiency?

The Efficiency of the transformer is defined as the ratio of useful output power to the input power. The input and output power are measured in the same unit. ... Transformer efficiency is denoted by Ƞ.

What is the symbol of a transformer?

When a transformer has a centre tap, the symbol consists of two circles with a line joining one of the circles. Here is alternative qualified version, which also has dots to indicate the instantaneous voltage polarity.

Which transformer is used in home?

In distribution networks, the step-down transformer is commonly used to convert the high grid voltage to low voltage that can be used for home appliances.

What is the kVA rating of a transformer?

kVA stands for Kilovolt-Ampere and is the rating normally used to rate a transformer. The size of a transformer is determined by the kVA of the load. In many circumstances the power required by the load is equivalent to the rating of the transformer expressed in either VA or kVA.
