Queensland’s export Awards program is an annual event open to all Queensland exporters, large and small, regional and metropolitan.

Now in its 23rd year, the awards program is the state’s highest recognition of exporting achievement. the awards program provides a showcase for top exporters and recognises enterprising excellence for the export of goods and services and the positioning of Queensland in the international market.

“Growing exports in this challenging global environment is no mean feat,” said Queensland Premier

Campbell Newman in a statement. “these Queensland companies [recognised in the awards] have achieved great success through innovation and determination to meet the changing needs of the global export market.” mr Newman made specific reference to NOJA Power. “NOJA Power switchgear is a Queensland company at the top of its game, providing electrical infrastructure to countries with swelling populations and industries,” he said. “[the company] epitomises the success story of a Queensland company which has started out small, and gone on to bigger things.”

NOJA Power was formed in 2002 by Neil O’sullivan, Oleg samarski, Jay manne and Quynh Anh le. the founding directors still run the company that now employs 150 people and exports to 80 countries on every continent.

the company’s products are used in the distribution of electricity by utilities, improving the reliability of supply, lowering the cost of power, easing the challenge of integrating renewable energy into the grid and helping to reduce carbon emissions from generating stations.

“NOJA Power’s very first sale was to an overseas firm and the company has grown up with an export focus ever since,” said NOJA Power managing director Neil O’sullivan.

“Nonetheless, to win this export award even once was a major achievement for the firm; to win it three times in six years is exceptional and a testament to the hard work and commitment of all NOJA Power’s staff.”

Accepting the award, mr O’sullivan said the company’s international success comes as a result of giving quality service and tailoring specific products to meet the needs of growing regions. NOJA Power has increased its export sales by 90 percent in the last year alone.

“Our continued investment in research and development to create quality products recognised as leading-edge technology in the world today underpins our business success,” he said.

As a Queensland export of the Year, NOJA Power now progresses to the Australian export Awards, a program it also won in 2009. the Prime minister’s Australian exporter of the

Year will be announced on November 27, 2012, at Parliament house in Canberra.

international standards were introduced to detail minimum specifications for reclosers such that the products performed reliably and safely. NOJA Power highlights the importance of type test Certificates to overcome confusion in the market as to which independent test house documentation proves that products fully comply with the standards.

Brisbane, Qld, Australia – electrical switchgear engineers NOJA Power today highlights the importance of type test Certificates as proof of compliance with international standards such as ieC62271-111 and ieee C37.60 for automatic circuit reclosers (see “About ieC/ieee international standards” below).

NOJA Power is clarifying confusion over test documentation by informing customers that only type test Certificates issued by independent test houses prove that a product has been verified to meet full ieC and ieee standards. the company advises that while alternative documentation such as reports of

Performance can be useful for recording tests on particular aspect of a recloser’s switching at 630 A, cable charging, line charging, dielectric withstand capability including 170 kV Bil across the open gap and 195 kV Bil phase-to-phase and phase-to-ground, wet and dry power frequency, temperature rise and mechanical operations testing.

the Osm38 recloser passed testing and NOJA Power received three type test

Certificates from dNV KemA, confirming successful testing and full standards compliance.

type test Certificates – certificates with a gold label issued by KemA, are the only documents which certify that medium-voltage switchgear products have completed and passed testing to verify that they meet international standards such as ieC62271-111 and ieee C37.60

electrical function, they are not proof of compliance to international standards covering recloser electrical functionality and do not even state whether the product has passed or failed testing.

“type test Certificates – such as certificates with a gold label issued by KemA, an independent test laboratory - are invaluable and unique because they are the only documents which certify that medium-voltage switchgear products (and all other components used in systems for the transmission and distribution of electrical energy) have completed and passed testing to verify that they meet international standards such as ieC62271-111 and ieee C37.60,” said Joop hooijmans, General manager of KemA high-Power laboratory in Arnhem (see

“About dNV KemA” below).

“Other types of documentation, for example reports of Performance, are useful but should never be taken as proof of product compliance with international standards as they are not intended for that purpose. Other types of documents always have to be studied carefully,” noted hooijmans.

NOJA Power’s Osm reclosers (see “About the NOJA Power Osm recloser range” below) have been subjected to full type testing by independent test consultants dNV KemA. the Osm38 recloser, for example, was tested for electrical performance including interruption duty cycle at 12.5 kA, load type test photo and details from NOJA Power Osm recloser type test Certificate report the Osm15 and Osm27 products have similarly been tested and received type test certification from dNV KemA.

“Our advice to utilities is to ask the manufacturer for a type test Certificate from an independent laboratory to be sure that the recloser complies with the relevant aspects of the international standards and will perform reliably for many years,” explained Oleg samarski, NOJA Power’s service & Quality director. “At NOJA

Power we ensure all our Osm reclosers are certified so that our customers are reassured that our products perform reliably and are completely safe.

About IEC/IEEE international standards the Geneva-based international electrotechnical Commission (ieC) and New

York-based institute of electrical and electronic engineers (ieee) publish international standards for the electrical, electronic and related industries. international standards ensure that manufacturers develop products that meet defined specifications. since 2002, ieC and ieee have collaborated to avoid duplication when developing, adopting or revising international standards in order to accelerate their issue. ieC62271-111 and ieee C37.60 (“high voltage switchgear and controlgear – Part 111: Overhead, pad-mounted, dry vault, and submersible automatic circuit reclosers and fault interrupters for alternating current systems up to 38 kV”) covers the design, manufacture and test of automatic circuit reclosers, was first issued in 2005 as a harmonised international standard and carries the logos of both organizations.

NOJA Power commends ieC for international standard revision specifying testing of arc containment and venting in cases of catastrophic failure due to phase-to-earth arcing in single-pole configured reclosers as it will encourage manufacturers to design products to fail in a controlled manner.

in the event of arcing, NOJA Power’s Osm pole-mounted recloser directs hot gasses towards the pole and upwards, minimising the risk to maintenance staff or members of the public that may be on the ground below

Brisbane, Qld, Australia – October 26, 2012 – electrical switchgear engineers

NOJA Power today advises that an amendment to the international standard ieC

62271-200† recognises that phase-to-ground arcing in single-pole configured reclosers can be a cause of catastrophic failure and the units should be tested for such an eventuality. Previously the standard mandated testing solely for three-phase units; now the standard calls for additional single-phase testing obligating recloser manufacturers to ensure appropriate arc fault containment is incorporated into their products.

the most likely cause of arcing is lightning strikes causing a voltage spike that overwhelms the recloser’s surge arrester and exceeds that Bil rating of the insulation system. failure could also be the result of multiple lightning strikes that degrade the insulation over time.

Although phase-to-phase arc faults in modern reclosers using vacuum interrupters embedded inside cyclo-aliphatic epoxy resin poles are unlikely, phase-to-earth faults can occur and units that incorporate no arc fault containment and venting can fail in a catastrophic and uncontrolled manner.

reclosers that have been appropriately designed for arc fault containment will fail in a controlled manner, eliminating danger to the general public, electricity workers and other equipment. the amendment to the standard details how the containment of these products should be tested.

section 6 and Annex AA of edition 2.0 of the standard comprehensively describe the

An arcing test demonstrates how a recloser designed for arc fault containment fails in a controlled manner internal arc test requirements for metal-enclosed switchgear and controlgear, intended to be qualified as internal arc classified (iAC).

in recognition of the importance of testing single-pole configured products, the standard goes on to note that the “arc fault current” is defined as “three-phase and

– where applicable – the single phase-to-earth rms value of the internal arc fault current for which the switchgear and controlgear is designed to protect persons in the event of an internal arc”.

Previous editions of the standard included iAC testing of phase-to-phase arcing in three-phase configured equipment, but omitted any requirement to classify phase-to-earth arcing in single-phase units.

“NOJA Power commends the ieC for addressing the earlier omission in the latest version of ieC 62271-200,” said Neil O’sullivan, CeO, NOJA Power.

“As a responsible and experienced switchgear producer, NOJA Power has always ensured that our solid dielectric auto recloser products have complied with the requirement for arc fault containment and venting as defined by ieC62271-200. if failure occurs, internal arcing is contained and any gases generated during arcing are safely vented,” explained O’sullivan.

“what the amendments to this standard now imply is that all solid dielectric equipment – even with single pole configurations

– need to be arc fault contained and vented and this is an important step forward for this standard and the safety of polemounted switchgear.”

Arcing test includes examining the effects of recloser failure on fabric samples designed to mimic human skin. directing hot gasses towards the pole and upwards maximises the safety of personnel below the recloser

NOJA Power’s Osm range of medium-voltage (15, 27 and 38 kV) reclosers (see “About the NOJA

Power Osm range”) feature patented arc fault containment and venting achieved by manufacturing the tank from stainless steel and providing an arc vent in the pole side of the unit. in the event of arcing, the hot gasses are directed towards the pole and upwards, minimising the risk to maintenance staff or members of the public that may be on the ground below the recloser.

the products have passed arc fault containment and venting testing conducted by test & Certification Australia and covering the five criterion specified in the international standard: correctly secured doors and covers do not open; no fragmentation of the enclosure for the duration of the test; no projection of small parts, up to an individual mass of 60 g; arcing does not cause holes in the accessible sides of the enclosure up to a height of 2 m, and indicators do not ignite due to the effect of hot gases.
