About The Course

Although the probability of failures of electrical equipment such as switchgear, transformers, protection systems and ancillary equipment are low, the consequences of failure can be substantial. It is therefore vital to keep up the switchgear safe and reliable.

This 2-day course is aimed at owners, operators and users of electrical switchgear in industrial and commercial organisations in both high and low voltage networks, plant and equipment. This training course will deal with the issues around design, maintaining and operating switchgear safe. It provides the latest UK industry practices and incorporates the very latest R&D work being undertaken by UK electricity utilities. It will help managers, engineers and others to understand their responsibilities and duties in the selection, use, operation and maintenance of high-voltage switchgear.

Safety issues associated with switchgear and the non- invasive diagnostic techniques in use today will be fully discussed. Degradation processes are well determined with the latest monitoring techniques as well as typical failure modes in switchgear and other electrical equipment. By using historic performance information, failure data coupled to modern diagnostic information and simple but effective asset management techniques the risk of failure can be considerably reduced. The learning process is also aided by the use of practical advice and case examples.

Learning Outcomes

The course has been structured to give electrical engineers, engineering managers and other professionals a comprehensive basis and understanding of the principles of keeping electrical switchgear safe with opportunity to learn about:

•    Discussion on possible issues with switchgear in operation

•    Importance of data management in the asset management system

•    Whole-life management approach

•    The main drivers for switchgear performance – overstressing, operation, modification and fault clearance

•    Maintenance practise of oil and non-oil switchgear

•    Assessment of ancillary equipment and enclosures

•    The assessment of aged switchgear & condition monitoring

•    Testing and commissioning

Who Should Attend

•    Electrical engineers, engineering managers, asset managers and other professionals working with or have responsibility for switchgear and ancillary equipment;

•    Ex-industrial staff or technicians who are now undertaking engineering duties in a power systems environment

In his 30 years working experience he provided highest quality services in system planning and analysis to major transmission and distribution and transportation companies including London Underground, National Grid Company (UK), MTRC Metro in Hong Kong, West Coast Main Line connection to NG, Scottish Power, ESB-Ireland, ESKOM-South Africa, Mauritius CEB, Balkan countries – grids of Romania and former Yugoslavia, HV network ISA-Colombia, Western Power Distribution-UK, etc.


Vukan’s technical expertise includes most aspects of power systems analysis, electrical asset management and railway connections to power networks where he provides solutions to technical problems and supports other field’s experts in complex assignments. He has project management skills in technical and environmental projects as well as experience in short and long-strategic term planning, maintenance and asset management, power quality analysis of transmission and generation systems, distribution, transportation and other power networks. Experienced in generation and network integration, electrical component of energy master plans as well as strategic asset replacement, he was also involved in load- forecast analysis and generation dispatching. Published papers on asset management based on projects and experience in working for distribution companies in Africa and Europe.


Vukan is very experienced in design, procurement, commissioning, erection and refurbishment of major projects in transmission and distribution substations up to 420 kV and hydro and thermal power plants. Served as project manager on several major projects as well as head of the Engineering Group, Vukan was responsible for final design, equipment specifications, layouts tender evaluation and commissioning. He has carried out conceptual development of protection and control philosophy for various projects as well as reviewed and approved project drawings and documents. He has applied the latest IEC standards, various codes of practice and engineering recommendations.  He has also specific experience in conceptual design of power supply for transportation and traction railway systems, defining the design principles and technical specifications for future design and privatisation process. He has analysed quality of power supply for connection of AC and DC unbalanced load to power network and published papers on practical implementation. Vukan carried out feasibility studies on reactive compensation (SVC and MSC) focusing on voltage variation and harmonic distortion issues.


Vukan has performed technical and economic evaluations, cost benefit net present value analysis, of various transmission and distribution schemes and electrical equipment. He carried out a number of asset evaluation analysis on electrical equipment and published papers on asset management, reliability and maintenance. He has performed equipment assessment and residual life prediction as part of strategic asset management analysis for a major underground transportation company in Asia. His duties have also included equipment arrangement optimisation in particular reliability aspect in terms of failure rate and financial consequences as non-supplied energy to the consumers.
