Inspection of high voltage installations

The EHV domain, covering voltages above 50,000 volts AC and above 75,000 volts DC, is a network that allows the transport and supply of electricity on a regional or local scale.

A good power supply for your industrial site or your tertiary buildings is an essential factor to ensure an activity without any risk of interruption or electrical risk. Guaranteeing reliability, safety and performance, whether for new installations, renovations or annual maintenance and servicing, is Apave's job (HV substations and transformer cells, industrial electrical cabinets / wiring, lighting / switchgear / routing / distribution, heating).

What is

high voltages installations?

The inspection of high-voltage installations responds to different objectives, one of the most important of which is the need to protect people and property from the potential risk they may pose. Likewise, the inspections also serve to ensure the regularity of the electrical energy supply and to facilitate the adaptation of the installations to future load increases from the design phase.

 

Apave has extensive experience in carrying out the tests required for high voltage regulatory inspections (Passage and Contact Measurements, Insulation Measurements and Adequacy of Safety Devices).

High voltage lines

High voltage lines

High voltage lines are the highest voltage lines in an electrical system, the longest and handle the largest blocks of power. In order to transport electrical energy over long distances, minimising losses and maximising the power transported, it is necessary to raise the transport voltage.

 

High voltage is considered to be any nominal effective voltage equal to or greater than 1 kV. High-voltage power lines, understood as three-phase alternating current lines at a frequency of 50 Hz, whose nominal effective voltage between phases is greater than one kilovolt.

 

Royal Decree 223/2008, of 15 February, approving the Regulation on technical conditions and safety guarantees on high-voltage power lines and its complementary technical instructions ITC-LAT 01 to 09, establishes the types of inspection to which they must be subjected and their frequency.

 

Types of inspection

  • Initial Inspection
  • Periodic Inspection

 

Periodicity

  • At least every 3 years

Power stations, substations

and transformer stations

This second group within high voltage refers to alternating current installations, whose effective rated voltage is greater than one kV, between two conductors, with a service frequency of less than 100 Hz. Therefore, it includes all electrical installations of sets or systems of elements, components, structures, apparatus, machines and working circuits between the aforementioned voltage and frequency limits that are used for the production and transformation of electrical energy or for carrying out any other energy transformation with the intervention of electrical energy.

 

Royal Decree 337/2014, of 9 May, approving the Regulation on technical conditions and safety guarantees in high-voltage electrical installations and its Complementary Technical Instructions ITC-RAT 01 to 23, establishes the types of inspection to which they must be subjected and their periodicity.
