Transformer Vector Group Test Method

This post categorized under Vector and posted on September 12th, 2018.

Vector Group Test of Transformer The vector group of transformer is an essential property for successful parallel operation of transformers . Hence every electrical power transformer must undergo through vector group test of transformer at factory site for ensuring the customer specified vector group of transformer.55(2)The transformer vector group is indicated on the Name Plate of transformer by the manufacturer. The vector group indicates the phase difference between the primary and secondary sides introduced due to that particular configuration of transformer windings connection.Answer vinod. Vector group is punched on the name plate based on the user requirement by the manufacture. Aim of vector group test is at site is to check if their is any damage in the windings

Transformer Vector Groups Definition The transformer vector group show the phase difference between the primary and secondary sides of the transformer. It also determines the high voltage and low voltage windings arrangement of three phase transformers.The three phase transformer is connected in Nov 07 2004 The test-method in my previous answer came out of the J&P Transformer Book pg310 (12th edition) Ive taken a small 3-phase 1200380V 4kVA trsf (Dy11) and have done a few tests with a voltmeter to determine vector-groups.May 23 2012 Vector Group of Transformer Displacement of the low voltage winding vector varies from zero to -330 in steps of -30 depending on the method of connections. In star-star transformer how can we do vector group test Reply. Fuad Arshad says August 23 2013 at 656 am. Thanku I liked ur post. Regards.

The method of comparing the vector couple voltages also allows measuring the angle (phase slip) between vectors at the same time.. 2. Determining the Connection Group. Depending on the type of the transformer the input and output windings of a multi-phase transformer are connected either as star ( Y ) or delta ( D ) or zigzag ( Z ).The phase angle between the high voltage and the low voltage
