Delta to delta transformer connection:

This diagram shows how to make Delta to Delta transformer connection. In this circuit, we will describe how to connect the delta to the delta transformer. A type of three-phase power transformer known as a delta-wye transformer includes coils connected in a delta pattern on the primary side and coils connected in a wye or star pattern on the secondary side. The Y connection can be completed with a neutral wire. Either a single three-phase transformer or three single-phase transformers can be used to create it. The delta-star transformer is its alternative name.

Components used to make the Delta to delta transformer connection:

01. Transformer:

The primary voltage of the transformer is 11 KV and the secondary is 0.4 KV high voltage. This is a delta star transformer, the high voltage of this transformer uses a delta connection and the low voltage uses a star connection.11KV power transformers are commonly used in power transmission substations to step down high-voltage transmission to distribution levels. 11KV transformers are more often used in distribution substations and on utility poles to further step-down voltage for supply.

Frequently asked questions

Why Delta is used in the transformer?

Why do we use delta-star in the transformer? The low voltage side of the main transformer is triangulated to eliminate the third harmonics. Prevent a large number of harmonics to the system, resulting in power grid voltage waveform distortion.

Why Delta-delta transformer is not used?

Delta-star connected transformers were widely used in low power supply distribution with the primary windings providing a 3-wire balanced load to the utility company while the secondary windings provide the required 4th-wire neutral or the earth connection.

What is a Delta delta connection in a 3-phase transformer?

the delta connection, the line voltage was equal to the phase voltage. The line current is equal to √3 times of phase current supply. The delta-connected 3ϕ transformer could be used for both balanced and unbalanced loading. In the delta connection, the 3rd harmonic component flows rounds the closed loop of the delta.

Where is the delta transformer used?

The delta/delta connection, as shown in Figure 1, was used for applications where only one 2nd voltage was required or where the majority of the load consists of 3-phase equipment, such as factories that have large 3-phase 480 V or 240 V motor loads or relatively small 120 V lighting and receptacle the loads.

Can I connect two transformers?

3 conditions must be met before you can connect transformers in parallel. 1. The transformers must have the same primary and 2nd voltage ratings. If the voltage ratings of the transformers were not the same, large circulating currents would flow in both the primary and secondary windings.
