Upon the request of a customer, we verify the operational and maintenance condition of electrical facilities and their compliance with the technical standard. Also, we use excellent technological power and advanced measurement instruments for effective maintenance and management and prevention of electrical disasters, and when contracted to do so, we perform monthly electrical safety inspections on small-scale electrical facilities..

General contract inspections


performs monthly inspection on electrical facilities used by an owner or occupant, so that they can be safely maintained and operated.


  • Schools and small buildings with voltage less than 600V and capacity less than 75kW.
  • Late night power facility or manufacturing facility with voltage less than 600V and capacity less than 100kW.
  • Performance halls, entertainment spots, large shops, hospitals and hotels with voltage less than 600V and capacity less than 20kW.

Advantages of contract inspections:

  • Emergency aid in the event of trouble with electrical facilities.
  • Periodic (monthly) safety inspection to prevent accidents.
  • Instruction on how to ensure electrical safety and save electricity.

Safety inspection on electrical facilities


Using excellent technological power and advanced measurement instruments, the operational and maintenance condition of electrical facilities and adequacy of the construction works is checked, so that customers can be provided with the data necessary to prevent electrical accidents and to effectively operate the facilities.


  • General safety inspection
    - General electrical facilities for houses and shops with electrical capacity less than 75kW.
  • Household safety inspection
    - Household electrical facilities for factories and buildings with electrical capacity greater than 75kW.

Advantages of safety inspection:

  • Power quality analysis and electricity use diagnosis.
  • Checks whether the main electrical facilities generate abnormal heat.
  • Self operation tests of circuit breaker and meters and interconnection tests with circuit breakers.
  • Bus bar, device contacts and electrical facility insulation thermalization measurement.
  • Electrical wiring, electrical device insulation resistance and ground resistance measurement.
  • Checks compliance with the electrical facility technical standards.
