Regulating Device for 100Kv Test Transformer

   
   
   
   
The major activities of HIVOTEC separate into 3 sections viz:  
   
Training and research in High Voltage Engineering.  
HV equipment testing standardization and maintenance.  
Consultancy services.  
   
The envisaged program of each section will be highlighted below.  
   
Training and Research:  
   

This falls under the portfolio of the scientific coordinator who is nominated by the University and reports to the board. He/She is not strictly HIVOTEC staff at this initial stage but holds a position in the University.

 
   
The responsibilities of the scientific coordinator include:  
   

Scan global developments in High Voltage Engineering(HVE) to access trends with a view to updating HIVOTEC’s techniques.

 
     

Source for students to aid research and service the scientific co-operation agreements

 
     

Conceptualise future research directions based on current research results, world trends and industry needs.

 
     

Identify, evaluate, select and customise training courses/ workshops/seminars in the relevant areas of the power industry.

 
       
 

Develop and implement long term human resource plans so as to produce experts where they are lacking.

 
       
 

It is proposed that research topics should be industry oriented so as to solve real life problems of the industry. Where possible, the student carrying out such research work should be jointly supervised by an academic and a practising engineer in the relevant industry. Financial assistance should be made available where necessary to cover the experimental aspect of such research endeavours.
Some useful research topics which have been canvassed include:

 
     
  Condition based evaluation of HV equipment  
  Techniques of AC- on site testing of HV cables  
  Life cycle assessment of substations  
  Transmission system reliability  
  Studies on various sources of technical losses on the NEPA network  
  Impact of stretched transmission systems on expansion planning.  
  Effect of lightning on various sensitive HV devices - voltage transformers, current transformers, etc  
     
  High Voltage Equipment Testing, Standardization and Maintenance.  
     
 

This aspect is purely technical and falls under the portfolio of the Technical Managers with the Director General supervising. The jobs should be evaluated and costed in the usual professional manner. Depending on the payment schedule, the job is then executed professionally using state of the art facilities. The goal is to achieve equipment certification in line with ISO 9000 or its equivalent. Details of how this should be carried out is the subject of another presentation.

 
     
  Consultancy Services.  
     
 

This forms the link between training, research and equipment handling. It will usually demand for the whole resources of HIVOTEC- human and material. For instance, specialized training/ workshop/ seminars may be organized for industry on specific areas of HV engineering. Other possible services include HV installation data base development, life cycle assessment of substations, load flow studies to determine the stress level of transmission lines, full scale study of partial or total grid collapses, risk level calculations and contingency analysis.

 
     
 

To promote training and research in High Voltage Engineering through undergraduate and post graduate programmes.

 
     
  Provide the much needed manpower and expertise for PHCN and industry.  
     
 

Provide modern facilities for industrial High voltage testing and measurements with a view to acting as certification centre of international standard for HV equipment and devices.

 
     
 

Develop/acquire state of the art techniques for online assessment of HV equipment including condition based evaluation
