4.1
General
The design and construction of the transformers and their components and parts
must be Fit for Purpose and Fit for Duty in all respects as described in this
specification and its applicable documents.
The transformers shall be suitably stiffened and braced to prevent distortion or
damage under service conditions and during handling and transport.
All sharp points on the transformer’s exterior surfaces will be removed to prevent
injury. All fixings shall conform to Australian metric standards and shall be
galvanised mild steel unless otherwise specified. Compatible materials shall be
used for all fixings to prevent corrosion.
4.2
High Efficiency Low Loss Design
Horizon Power’s regional business has historically operated under the burden of
high generating costs for the electricity it distributes. Horizon Power is alert to the
possibility of reductions in the life-cycle costs of its MV Distribution Transformers
through the use of developed high-efficiency transformer technologies. Horizon
Power seeks to assess the life-cycle cost of (so-called) “low loss” transformer
technologies in the hope of not only achieving superior energy efficiencies but of
also making cost savings for its customers.
It should be clearly understood that Horizon Power has NOT committed to the
purchase of alternative transformer designs to time-proven, industry standard
distribution transformers. This transformer specification does NOT exclude
industry standard distribution transformers.
Information and data submitted by Vendors of transformer design will be
evaluated by Horizon Power with a strong focus on whole-of-life costs.
4.3
Loading
The transformers shall be suitable for loading in accordance with AS 2374,
Part 7. No part of the transformer (e.g. bushings or tap changer) will impose
restrictions on the loading capabilities.
4.4
Radiators
For transformers requiring cooling radiators, the radiators shall be of the fin-wall
type and shall be welded directly into the tank sides and/or tank ends. Fins shall
be mechanically stabilised to the approval of Horizon Power.
Special attention shall be given to ensuring that all surfaces of the fins are
galvanised or painted to the same standard as the external tank surfaces. Refer
to Section 4.13 for painting.

4.5
Tanks and Lids
Transformers shall be of the sealed tank construction type as per
AS/NZS 60076.1 Clause 8.2. Sealed transformers shall not be pressurised, nor
shall they contain gases other than dry air or suitable inert gas. Diaphragm
sealing is not acceptable.
All surfaces will be designed to prevent the accumulation of water. All seams will
be electrically welded and oil tight.
On the external areas of the tank, welding of horizontal and vertical joints will be
on both sides of the joint. Welding in all cases will be continuous.
All metal work will be electrically bonded to the tank to permit earthing by the
Purchaser. If a part cannot be adequately bonded it will be constructed from a
suitable insulating material instead of metal.
The tanks will be so designed that, with a top oil temperature of 105°C, the oil
level in the tank will be below the tank lid flange.
4.6
Joints and Gaskets
All bolted joints shall be rendered oil tight by the use of neoprene cork gaskets or
other sealing methods. All gaskets/seals shall be designed to last the life of the
transformer. Joints in gaskets shall not occur at bolt holes. Where tank covers
are bolted rather than fully welded, the sealing method must be submitted to
Horizon Power for approval.
4.7
Core
The transformer core material will either be cold-rolled, grain-oriented silicon
steel or amorphous silicon type. The effect of the offered core material on core
losses is expected to be a key point in assessing the whole-of-life cost of the
transformers offered.
The core and winding assembly shall be supported by the main tank and not by
the cover.
The transformer core shall be centrally located in the tank and secured at both
the top and bottom of the core-coil assembly to prevent damage during
transportation.
The core and all metalwork shall be electrically bonded to the tank. The bonding
of core/cores shall be brought to one point only.
4.8
Windings
All transformers shall have electrically separate medium voltage and low voltage
windings. Winding connections shall be in accordance with AS/NZS 60076.1.
Vendors may offer transformers with either copper or aluminium windings.

4.8.1
Single Phase Transformers
Single Phase Transformers shall have two low voltage windings which may be
connected in series or parallel. The ends of all windings shall be brought out to
external bushing terminals so that either a series 3-wire 500/250 volt or parallel
2-wire 250 volt supply can be conveniently selected by means of pre-formed
links.
The series/parallel connecting links shall be supplied with the transformer. The
transformer shall be supplied with the links configured for 250 volt operation.
The voltage regulation of either low voltage winding shall not exceed the value
permitted by AS/NZS 60076.1. The voltage regulation is measured when one low
voltage winding supplies load equal to half of the transformer rating and the other
low voltage winding is open circuited.
4.8.2
Three Phase Transformers
Three Phase Transformers shall be connected in accordance with the vector
group symbol given in Table 7, Other Requirements for Three Phase Aerial
Transformers.
4.8.3
Single Wire Earth Return Distribution Transformers
Single Wire Earth Return (SWER) Transformers shall operate with one end of
the medium voltage winding connected to earth. The end of the winding to be
earthed shall be brought out of the tank to an earth return terminal through an
adequately rated bushing. A removable tinned copper earth strap of section
20 mm x 1.5 mm or equivalent shall be provided and connected between the
earth return terminal and the tank.
These transformers shall also comply with the requirements for Single Phase
Transformers with two low voltage windings as set out in this specification.
4.8.4
Isolation Distribution Transformers
Isolation transformers shall have two primary MV bushings (A1 & A2) for
connection to the MV network, one MV bushing (a1) for connection to the SWER
MV network and one LV bushing (n) for connection to earth.
4.9
Tappings
Each transformer will be capable of off-circuit tap changing by means of an
externally operated seven position tapping switch complying with AS 60214.1.
Seven tap positions will be provided on the high voltage winding. The tapping
range for each unit will be +10% to –5% of rated voltage with a tapping step of
±2.5%. Tap position 1 will correspond to the full winding in circuit.
The tapping switch will have a permanent overload capability of 50% i.e. 150% of
nameplate full load current of the transformer.
The tapping switch will be located near the top of the transformer for ease of
access and to readily facilitate un-tanking of the transformer.

The tapping switch will be capable of being locked in every position. The locking
arrangement will make it impossible to lock the switch between tap positions.
Each tapping selector switch position will be identified by a number clearly and
indelibly stamped on to either the switch operating handle or the transformer
tank.
The MV connection to the tapping switch shall be made by means of bolted or
crimped connections.
A sealing gland will be provided on the tapping selector switch operating shaft
where it passes through the transformer tank to prevent any breathing or leaking

Performance Criteria
4.15.1
Minimum Power Efficiency (MEPS)
All transformers must meet or exceed the minimum power efficiency levels
specified in Table 1 of AS 2374.1.2 - Minimum Energy Performance Standard
(MEPS). Transformers with efficiencies not meeting or improving performance
upon these MEPS levels are unacceptable.
During the term of the Contract, the Purchaser reserves the right to negotiate
with the Vendor to enhance the Transformer Power Efficiency levels to meet any
future amendments to the MEPS requirement in AS 2374.1.2.
4.15.2
Guaranteed Transformer Losses
In evaluating the Tenders, the Purchaser will capitalise the guaranteed losses
and determine the economic advantages of the transformers offered.
Transformer losses will form a major part of the proposal assessment.
Capitalisation of losses will be based on the guaranteed losses, at the required
power rating for each item to be provided by the Vendor as stated in Appendix C,
Technical Schedules. Load losses will be those applying on the principal tapping.
The following formula will be used for the purpose of making a fair economic
comparison on the Life Cycle Cost (K) of the transformer based on the average
cost of energy.
K = A + Ci*Wi + Cc*WC
Where:
A = cost of purchasing AUD$;
Ci = capitalised cost of no-load loss, given as $62,635.00/kW *;
Cc = capitalised cost of load loss, given as $2,029.00/kW;
Wi = no-load losses (iron loss), kW; and
Wc = load losses (copper loss), kW
for the transformer.
The economic life of a transformer is assumed to be 50 years.
* NOTE:
DM# 3678175
The typical value in Australia for the value of Ci, in equation above, is
between $5,000.00 and $7,200.00.

4.15.3
Allowable Tolerance for Transformer Losses
As specified in AS 60076.1, the maximum allowable tolerance for the total losses
for all transformers to be supplied to this specification is +10%. For any
transformer, the maximum allowable tolerance for either the no-load loss or load
loss is +15%, provided that the total loss meets the above requirement of +10%.
Where the total loss exceeds the +10 % tolerance or either the no-load loss or
load loss exceeds the +15 % tolerance, the Purchaser reserves the right to reject
the unit.
4.15.4
Transformer Impedances
The impedance voltage at rated current on principal tapping will be generally as
specified in Tables 6 to 10.

GROUND-MOUNTED TRANSFORMERS
6.1
Supply of Packaged Substations
Ground mounted transformers used by Horizon Power form part of singletransformer packaged substations which are supplied as integral units. Ground
mounted transformers shall be supplied under this specification in customised
packaged substations which are similar to, but not necessarily identical to,
packaged substations currently used by Horizon Power. Packaged substation
units are required to provide the functional features of existing packaged
substation units in all essential respects.
It is desirable that packaged substation units supplied under this specification are
compatible with existing packaged substations in certain key respects. The key
respects include:
1)
the same operating and maintenance features as existing packaged
substations;
2)
the same arrangement of bushings;
3)
the same mounting heights for MV and LV cables;
4)
a similar overall footprint of transformer-and-MV/LV cubicle assembly.
The Vendor is requested to pay close attention to providing physical compatibility
with the existing packaged substations. All points of physical incompatibility with
existing substation packages should be noted in Appendix E, Departures from
the Technical Specification.
It should be understood that physical variations from the existing packaged
substation designs will not automatically be treated as non-compliances with this
specification. Horizon Power will consider the consequences of accepting
changes from the existing packaged substation designs. The Vendor’s attention
is drawn in this context to dimensional changes which would compromise
Horizon Power’s ability to replace or interchange packaged substation units.
There are three basic types of packaged substations in Horizon Power’s
business. The physical arrangements and key dimensions for the packaged
substations are shown in Appendix G and listed in Section 2.3. The three basic
types are:
1)
Modular Packaged Substations (MPS)
2)
Non-Modular Packaged Substations (Non-MPS)
3)
Single Phase Rural Packaged Substations (SPUDS)
The functional features of existing packaged substations are described in the
following sections. These descriptions are provided for information purposes and
can be taken as representative of the existing packaged substations. Similarly,
the drawings in Appendix G are provided for information purposes.
