1 Single Phase IEC and EATS Distribution Transformers
INTRODUCTION TO RANGE Single Phase IEC and EATS Distribution Transformers

2 INDEX Range Standard Features Optional Features Routine Tests
Type Tests Why use ABB?

3 RANGE Single phase 15kVA to 100kVA Smaller kVA available on request
Voltage level - primary voltage of up to 36kV Units manufactured to IEC, EATS or Special requirements

4 STANDARD FEATURES Sealed or free breathing tank
Hot dip galvanised tank Lifting lugs Rating plate and connection plate Earth tag Upper and lower pole mounting brackets

5 OPTIONAL FEATRUES Lid or turret mounted bushings
2 or 3 wire arrangement Internal HT fuses Single or dual ratio Off circuit tap switch or internal link board Arcing horns Surge arresters Oil level on free breathing units

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
