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

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

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

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

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

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.

WHY USE ABB? Manufacture complies with: -ISO9001 Quality system -ISO 14001 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

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
