A 3 phase transformer star-star connection is considered to be the backbone of electrical power distribution even if they are meant to be used as a Delta or Star connected windings. Typically speaking, a transformer will not act as a phase changing device and change a single phase one into a three phase or vice versa.

To make the transformer connections well suited with three-phase supplies, the manufacturer will need to connect them together in a specific way such that it forms a 3 Star Transformer Configuration.A three phase transformer or a 3 phase transformer star connection could be constructed either by connecting together three single-phase transformers, which would then result in the formation of a so-called three phase transformer bank. Or another way could be by using one pre-assembled and balanced star delta 3 phase transformer which consists of three pairs of single phase windings, that are then mounted onto one single, but laminated core.

The advantages of building a single delta star connection of 3 phase transformer is that for the same kVA or Kilo-volt-ampere rating it would be smaller, cheaper and lighter as compared to three individual single phase transformers connected together. This is because the 3 phase delta star transformer calculations also has addition of certain elements such as copper and iron core, which can be used more effectively. The methods of connecting the primary as well as the secondary windings are the same, whether using just a single delta-star 3 phase transformer or three detached Single Phase Transformers.

The primary and secondary windings of a star star connection of 3 phase transformer could be connected in different configuration such that the transformers 3 star cast can practically meet any requirement. For instance, in the case of windings, according to the 3 star transformer manufacturer in himachal Pradesh,  three forms of connection are possible i.e. – star or wye or 3 star transformer specification, delta which is referred to as mesh or 3 phase delta star transformer  as well as interconnected- star which is also known by its zig-zag form.

To learn more about the price of these from 3 star transformer manufacturers in India. The combinations of the three windings could be  interchanged in such a way that these 3 star rating transformer follow either the primary delta-connected and the secondary star-connected, or star-delta, as well as the star-star or delta-delta, depending on the use of the 3 phase transformer star delta connection.

A 3 phase star transformer has three sets of primary and secondary windings. Depending upon how these sets of windings are interconnected, the 3 star transformer manufacturer Mumbai will  determine whether the connection is to be either a star or delta configuration.

Star Rated Transformers are energy effective transformers begun as a “Green Campaign”. These are transformers that carry standard details as per Bureau of Energy Efficiency (BEE). The referred Indian Standard are IS1180 (part 1) Outdoor type three-phase distribution transformers upto and counting 200kVa, 11kV – detail, IS2026 (part 2). The standard evaluations secured beneath this pilot energy naming scheme is 16, 25, 63, 100, 160 and 200kVa and non standard evaluations from 16 to 200kVa.

The notable highlight of the 3 star rating transformer is the truth that only add up to losses are indicated, both at 50% loading and at 100% loading, so that the manufacturer may utilize his plan skill and ideal materials to attain the given losses. Individual loss figures (no load loss and load loss) are not indicated. We’ve accomplished 3-Star BEE names for these evaluations, with tests of each rating being Type Tested in a NABL Lab before accomplishing the Star Name. These transformers are majorly obtained by SEBs/DISCOMs & by Turnkey Companies executing projects on behalf of SEBs/DISCOMs.

Υ – Δ (Star – Delta ) Connection (OR Wye-Delta)

• The primary winding is star star (Y) connected with grounded neutral and the secondary winding is delta connected.
• This connection is mainly used in step down transformer at the substation end of the transmission line.
• The ratio of secondary to primary line voltage is 1/√3 times the transformation ratio.
• There is 30° shift between the primary and secondary line voltages.

 

---

Υ – Υ (Star – Star) Connection

• Star-star connection is generally used for small, high-voltage transformers. Because of star connection, number of required turns/phase is reduced (as phase voltage in star connection is 1/√3 times of line voltage only). Thus, the amount of insulation required is also reduced.
• The ratio of line voltages on the primary side and the secondary side is equal to the transformation ratio of the transformers.
• Line voltages on both sides are in phase with each other.

Δ – Υ (Delta – Star) Connection(OR Delta-Wye (Δ-Y))

• The primary winding is connected in delta and the secondary winding is connected in star with neutral grounded. Thus it can be used to provide 3-phase 4-wire service.
• This type of connection is mainly used in step-up transformer at the beginning of transmission line.
• The ratio of secodary to primary line voltage is √3 times the transformation ratio.
• There is 30° shift between the primary and secondary line voltages.
