Title: Distance Protection



Contact Hours: 3 Hours Technical

Language: English

Format: Lecture (No Video)



Since the impedance of a transmission circuit is relative to its length, for distance measure it is suitable to use a relay able to measure the impedance of a circuit up to a present point (the reach point). Such a protection relay is known as a distance protection relay and is made to function only for faults happening between the protection relay location and the chosen reach point, therefore providing discrimination for short circuits that may happen in different line portions.

Distance protection, is a non-unit protection arrangement providing significant financial and technical benefits. Unlike phase and neutral overcurrent protection arrangements, the key benefit of distance protection is that its short circuit current coverage of the protected element is almost autonomous of source impedance changes.

This course is suitable for engineers with a desire to understand the fundamentals of distance protection. Presented details cover issues related to distance protection technical implementation. Upon successful completion engineers will be able to address key distance protection concepts, terms, zones and characteristics.


Learning Objectives:

This continuing education course is intended to provide you with the following specific knowledge and skills:

  • Basic theory and terms of distance protection
  • Distance protection zones
  • Distance protection characteristics
  • Distance protection relay application


About The Author 

Velimir started his professional career in the Electrical Engineering Institute "Nikola Tesla" Belgrade as Project Engineer working on various distribution system planning projects. He moved to Middle East where he is involved in analysis and planning of the EHV and MV transmission and distribution networks as well as conceptual and detailed design, installation and commissioning of substations for major consultancies and local utility companies. He also got significant experience working for the major oil companies solving their complex operational issues helping them to improve overall production.

He modelled various phenomena in the power systems including steady state, dynamic, harmonic and fast transient responses. He has good knowledge in substation design, HV cable sizing and installation and earthing system design. He understands how projects are successfully managed throughout complete cycle. He has profound knowledge of power system modelling and analysis software tools, CAD design and GIS systems.     

He has rich experience working on projects in UK, Qatar, United Arab Emirates, Malaysia, Bahrain and Serbia. Velimir authored several technical papers that were published in IEEE proceedings. He is a member of IEEE Power Society and CIGRE.
