6. ROUTINE TESTS
Each transformer produced is routine tested in accordance with IEC 76
The tests performed are:
Winding resistance
Voltage ratio and phase displacement
Short-circuit impedance and load loss
No-load loss and current
Dielectric

7. TYPE TESTS Type tests are performed on each new design per IEC 76
List of type tests performed
Temperature Rise
Impulse Test
Short circuit tests can be performed on request. This is a special test described in IEC 76 part 5.

8. WHY USE ABB? Manufacture complies with:
-ISO9001 Quality system
-ISO Environment Management System (Certification due Q1 2003)
Transformers are successfully in operation for over 50 years
Units designed using proven ABB common technology
Units can be optimised to suit particular loss requirements
ABB is a volume producer
ABB has experience of many specifications

9. WHY USE ABB? Short cycle times leading to shorter lead-times
The galvanised tanks ensure long life
Good quality and reliability
Pressure testing insures leak free products
Units have been successfully short circuit tested
