Electrical transients Test

This test checks equipment operation by applying repetitive electrical transient bursts over AC, DC, and signal and telecommunication power lines.

Electrical transients and/or bursts are generated by switching maneuvers in the interruption of inductive loads and contact bounce in relays, motors, compressors, etc.

Other types of equipment that unintentionally produce RF electromagnetic radiation energy include inductive load switches, arc welding equipment, fluorescent lights, etc.

⇒ Levels: Depends on the standard: from 500 V to 4 kV.

⇒ Criterion: After the test, the equipment must operate without any degradation or loss of function. A certain degradation of performance is allowed during the test (criterion B, usually).

Shock waves

  • This test checks equipment operation by applying bursts of overvoltage and overcurrent on AC, DC, signal, and telecommunication power lines.
  • Unidirectional shock waves are caused by transient overvoltages, such as those caused by lightning strikes or switching operations.
  • The effect of a direct lightning strike on the equipment is not considered.
  • Application: In common and differential mode. Furthermore, in the case of AC, the wave is coupled at different phase angles.

⇒ Levels: Depends on the standard: from 500 V to 4 kV.

L⇒ Criterion: After the test, the equipment must be able to operate without any degradation or loss of function. A certain degradation of performance is allowed during the test (criterion B, usually).

Drones Regulation transition period was established in Spain to implement the new drone regulation: The transition from local to community legislation The Commission Implementing Regulation (EU) 2019/947 entered into force last December 31, 2020. This new regulation makes a more inclusive framework for drone operations, ensuring and improving safety, security and sustainability.

Requirements for introducing drones into the European Market.
