Our team 

ResTech has a core team of experienced engineers. Our permanent staff are supplemented by academics from the University of Newcastle.

As part of the research process, staff are seconded to where our customers applications are located. This is aimed at ensuring our work remains focussed on delivering commercially viable solutions for industry.

The expertise of the ResTech staff is spread across power systems, electronics and computer systems (software development, microcontrollers, etc.). This mix of skills and experience is vital to the success of the company because of the increasing need to apply some traditional 'light current' techniques (digital control, communications, computer-controlled devices, etc.), to the power systems area.

Richard Griffiths

Richard Griffiths

Richard received a Bachelor’s degree in Electrical Engineering from the University of Newcastle in 1978. After brief employment at a telecommunications company and a local coal mine he joined Scientechnic (now Ampcontrol). For the next eighteen years he worked as a research and development engineer and the Technical Manager and was involved in the design, manufacture, installation and field support for a wide range of products, including mining protection relays, intrinsically safe systems, mine data transmission and control systems, battery chargers and large 415V and 1000V soft starters for mining conveyor belts. Around 1988, the work in power electronics began to extend into higher power areas such as traction rectifiers for trains (1550VDC) and trams (600VDC) and then to very high power rectifiers. 

Ampcontrol’s first “Rectiformer” (large water cooled rectifier and transformer combination) was designed and built for a copper refinery in Wollongong in 1989. As the principle designer of the rectiformers and their associated harmonic filters, Richard gradually spent more and more time working in this area and eventually transferred to the Power Division of Ampcontrol around 1996. In the period between 1989 and 2009 Ampcontrol constructed about 25 rectiformers and medium voltage harmonic filters with ratings up to 70,000 A DC and 25 Megawatt. Customers included Aluminium Smelters, Copper and Zinc refineries and Chlorine plants. 

Other work undertaken for Ampcontrol's Power division included extensive work on power factor correction system design, earth grid design, equipment cooling design and arc fault containment.

Richard transferred to Restech in July 2011 and has been contributing to work started by Tim Wylie and Peter Stepien on the analysis and simulation of IT power systems in underground coal mines and the impact of Variable Speed Drives and EMC filters.

Justin Gavranich

Justin graduated from Griffith University in 2012 with a Bachelor of Engineering in Electronic Engineering with First Class Honours and has since achieved exceptional success in the hazardous areas industry.

While completing his final year of studies at University, Justin joined the team at Connexa designing electronics for hazardous areas with a focus on safety. Justin’s professional skills developed at a rapid pace and after only 12 months was promoted to lead Certification Engineer for Connexa, where they relied on Justin's insight and interpretation of Standards to successfully achieve numerous key milestones in the design, development and marketability of their products in the mining industry. Some highlights include 13 Ex Certificates of Conformity to numerous standards in the AS/NZS 60079 series. As a result, a suite of these certified products were made available across both national and international markets increasing safety for Miners across the globe.  

It was this passion for safety and conformity to both Australian and International Standards that led Justin to apply for the 2014 Standards Australia Young Leaders Program. Only the top 10 applicants were accepted through a competitive selection process, opening the door to a world of possibilities where Justin gained exposed to the nation's peak non-government Standards Organisation. Justin was provided with the opportunity to grow as a young professional through personal development programs and involvement with voluntary technical committees. Since the completion of the program, Justin has joined a number of committees and sub committees as a technical expert, including EL-014 Equipment for Explosive Atmospheres, EL-014-04 Intrinsic Safety, EL-014-09 Gas Detectors, ET-006 Australian IEC Conformity Assessment and ET-006-01 Australian IEC Ex Conformity Assessment.

Since completion of the Standards Australia Young Leaders Program, Justin has gone onto attend the 2015 International Electrotechnichal Commission (IEC) Young Professional Workshop held in Minsk, Belarus. Justin was also one of the Australian delegates to attend the IECEx Management committee held in Christchurch, New Zealand in September 2015.

Justin was awarded the 2015 Griffith University Sciences Young Alumnus of the Year award for his willingness to take on an active role with both Standards Australia and also his representation of innovative product design in the hazardous areas sector. This milestone in his career, after only three years since graduation cements him as a young leader of the future in the area of hazardous area product design, conformity assessment and standardisation. As the 2015 Griffith Sciences Young Alumnus, Justin has gone onto inspire young Engineers of the future about his experiences in hazardous areas and standards development via a guest lecture at Griffith University in late 2015.

In 2016 Justin started work at ResTech where he currently holds a R&D Engineer – Embedded Systems position, bringing his expertise in hazardous areas, intrinsic safety, electronic design and conformity assessment to supplement the diverse capabilities of ResTech.
