Avid designed, assembled and tested a 33kV kiosk for the Karratha Airport. Designed to integrate renewable energy (solar) sources at the site with conventional power supplies, the kiosk comprises integrated transformer, ring main unit (RMU), switchboard and controls for power management at the site. Undertaken for CPS National, Avid worked closely with enclosure manufacturer Aerison for design and assembly of the transportable frame and portals, ensuring compliance with both Australian Standards and the environmental considerations for the location (including certification for Region D wind conditions and ensuring sufficient airflow for the ambient design temperatures).
The kiosk utilised Eaton 415V switchgear assembled at Avid’s workshop, integrated with ComAp inteliPro and Woodward MRU4 protection relays. The 33kV RMU and assorted metering cubicle were a Tyree supplied Efacec FLUOFIX 36. All the electronic devices were fitted with RS232 communications modules for integration with the Solar control system.
The installation integrated the earth grid, 1MW solar photovoltaic installation (using cloud predictive technology), Horizon Power’s grid and the Airport distribution system to ensure a reliable and sustainable power supply for the critical infrastructure at Western Australia’s second-busiest airport.
Tronox case study
Perth firm Avid Group says it will partner with a global leader in hydrogen technologies to bring leading-edge fuel-cell modules to the Australian market.
Avid will offer 1.4kW hydrogen fuel cells as an alternative power supply to traditional diesel backup generator sets in a partnership with UK firm Intelligent Energy.
Avid hopes to provide an alternative to diesel generators by offering a fuel-cell module that can provide back-up electricity without the associated emissions and noise of the diesel-fuelled options.
AVID Group is proud to launch our 2019 apprenticeship program whereby you will be contracted to an electrical contractor such as AVID Group to learn and become qualified in the electrical trade. It combines practical experience in the workplace with structured off the job-training at a contracted training provider such as the College of Electrical Training or TAFE you decide to join.
Our apprenticeships program at AVID Group offers you the ability to earn money while you learn a qualification and build practical skills. Applicants must be able to demonstrate the following:

There is a perception among some companies that electrical system tests are unnecessary, disruptive and costly, according to electrical contractor and Avid Group’s business development manager Aaron Teo.
Safe Work Australia reported that an average of 11 Australian workers were killed in Australia between 2003 and 2015 through contact with electricity, and that the risk of injury and death increased when working with electrical equipment outdoors, in damp environments or cramped conditions.
But this month’s World Day for Safety and Health at Work (28 April) is a timely reminder for mining companies to get their electrical systems checked, Teo said.
“No one talks about electricity, until there’s a major disruption or incident in their workplace,” he added.
Five electrical tests are recommended for heavy industry. The first one is to conduct a yearly audit to obtain a detailed assessment of the entire power network, update electrical drawings and get recommendations for new equipment or modifications to existing equipment.
Routine maintenance of equipment should also be regularly checked and maintained to ensure they are in serviceable condition and any possibility of an unplanned failure is mitigated.
The third electrical test is an assessment of the configuration of the existing electrical distribution system as well as testing points of failures.
Companies should also conduct a load flow assessment to demonstrate where electrical assets may be over- or under-utilised, identify which electrical assets are critical and which require upgrading to support connected loads.
The last test involves an equipment lifecycle assessment which tests the current condition of the existing electrical distribution system, age, availability of spares and compliance with the applicable standards.
These tests can be done at night, with minimal or no disruption to normal business operations, according to Teo.
“Too many companies take their electrical systems for granted – they’re putting workers’ lives at risk and exposing themselves to big fines and costly repair bills,” he said.
“Regular testing and maintenance of systems and equipment significantly reduces these risks.”
AVID is excited to build Logstrup 415V type test switchboard assembly in less than 8 weeks for an important customer in the western Australia Pilbarra region.
