Our Working Process
CORE
The Core is built from laminations cut from cold rolled grain oriented silicon steel sheets and special grade of lamination like MOH Grade, Laser Materials. The laminations are interleaved and usually have partially mitred or fully mitred joints.
The limbs and yokes are of graded section, thereby maintaining the same flux density and facilitating the assembly of cylindrical coils. In all cases the core is electrically earthed by means of copper strip.
WINDINGS
The Windings are made from electrolytic copper or aluminium conductor covered with either paper or enamel. The coils consist of any one of the following types:
- Spiral or Helical Coil
- Cross-over Coil
TESTING
Prior to despatch each transformer undergoes all routine tests as per relevant specifications.
- Ratio Test at all taps
- No load test at rated voltage and frequency
- 50% and 100% Load Loss test at rated current, rated frequency and impedance volts applied
- Temperature Rise Test
- Pressure Test
- Measurement of Zero Phase Sequence Impedance Test.
