STAROIP – Taking up the challengeDue to increased in-feed from renewable energy and more severe cycling loads higher requirements for transformer bushings exist.
STAROIP is the new generation of OIP (Oil Impregnated Paper) condenser bushing, designed and manufactured to satisfy even the most critical service conditions and cycling loads.
The industry-wide issue of copper migration was also considered in the design and testing.
The STAROIP series complies with international standards, and has been especially designed and tested according to IEEE C57.19.01-2004.
Our long term experience in transformers and bushings are the basis for a unique design that meets your transformer and reactor applications.
DesignThe fine capacitance graded core is wound onto the winding support inserting alumi-num foils to control the electrical field both radially and axially.
The head and flange consist of a weather resistant aluminum alloy. All O-ring seals are in a self-contained chamber and are made of temperature resistant elastomers.
Insulating OilThe bushing is filled with mineral oil as a part of the insulation.
The oil used in STAROIP bushings has a very low affinity of solubilizing copper, therefore the copper migration phenomenon into the insulation is avoided.

STAROIP – an OIP insulated bushing designed for the new challenges in the transformer industry
STAROIP – Unique design• New market requirements and
industry-wide issues considered• Oil volume compensation with
stainless bellow• Proven materials with long-term
experience• Rigorous test program performed
to simulate real life conditions way beyond IEEE standard requirements
3
Design features• Stainless steel bellows in the bushing head are
an advanced solution ensuring correct oil volume compensation, without overpressure / low pressure inside the bushing and eliminating the presence of gas in contact with the insulating oil. This solution replaces the common technology for oil volume compensation available on the market, which consists of a nitrogen cushion
• Stainless steel material used for bellows, in order to ensure the maximum reliability during the bushing’s lifetime
• Bellows are used and proven in other high-voltage applications such as Instrument transformers
• Superior corrosion proof resistance in severe ambient conditions
Basic characteristics• Air side insulator: Porcelain cemented into the flange
for increased cantilever withstand capability• Oil side epoxy insulator providing high impact
resistance and reduced size• Embedded end shield in the epoxy insulator eliminates
external shielding in draw lead applications up to 230 kV and provides greater internal clearances
• Horizontal transportation and storage possible• Draw lead adapters to allow replacement
of old draw lead bushings without modification of the existing stud & cable
• Standard creepage distance of 44 mm/kV (heavy pollution) USCD as per IEEE C57.19.100-2012 and 54 mm/kV (extra heavy pollution) available for ratings up to 230 kV Flange detail: test and voltage tap
Stainless steel bellows assembly
STAROIP – Your benefits• Solution also for cycling loading conditions
and for renewable energy applications• Maximum reliability due to special design,
rigorous testing and use of proven materials• Constant oil pressure, i.e. bushings operate
at same oil pressure as during routine test• More robust electrical design validated by highest
requirements of IEEE and IEC standards• Bellow design allows transportation, storage
and installation in different positions• High interchangeability with existing IEEE designs
makes them suitable for many retrofitting cases

Test tapSTAROIP – IEEE bushings rated 69 kV and below are provided with a test tap. This tap is usually grounded and is intended for measurement of power factor, capacitance from conductor to tap, as well as offering the possibility to connect to an on-line monitoring system. Since the capacitance from tap to ground is not controlled, the tap is not intended for use as a voltage divider during normal operation.
Bottom terminals according to IEEE Std. C57.19.01-2000
Additional terminals available
Voltage tapBushings with rated voltage starting from 115 kV and above are provided with a voltage tap as required by IEEE Std. C57.19.01-2000. Under normal operation the tap cover is installed and the tap is grounded. When opening the cap, it’s possible to connect the bushing to a monitoring device.
Oil sampling plugThe oil sampling valve is available on all voltage levels at the flange position. The plug allows all mainte-nance operations to be performed as described in the instruction manual.

Rigorous testing for maximum lifetime reliability
The new STAROIP condenser bushing with OIP active part is tested with stringent requirements: Type tests performed as per IEEE Std. C57.19.00-2004, but at highest electric values between IEEE and IEC
Additional special tests
1. Temperature cycle tests under operating voltageBushing under permanent operating voltage with simultaneous application of thermal cycling, to reproduce the severe cycling load conditions.
2. Mechanical withstand tests for bellows (> 10.000 full cycles)– Cycles are repeated until the
tightness is broken– Systematic tests for every bellow
design
3. Transportation tests as per ASTM D4169-01, including impact hazard and shake table test– Standard practice for performance
testing of shipping, containers and systems
– Tightness tests and routine electrical measurements repeated as acceptance criteria
