Learn about electrical failures

Do you know what electrical failures are?

There are many failure modes in the AC Power Supply. Avtek has developed innovative high quality devices that protect your home, office and industrial appliances. To facilitate understanding these failures, we explain below the 7 basic ones and regions where they are prevalent.

Electric Disturbances:

Cause: Electromagnetic or Radio Frequency noise propagating through AC lines, commutations in the distribution system, electric motors, non-linear loads, inadequate grounding, lightning discharges.

Effect: Inadequate operation of electronic equipment, shortened useful life.

Voltage Spikes:

Cause: Electromagnetic or Radio Frequency noise propagating through AC lines, commutations in the distribution system, electric motors, non-linear loads, inadequate grounding, lightning discharges.

Effect: Permanent damage to electronic devices.

Under Voltage (Sags):

Cause: Energy generation and transportation issues, grid overload, being at the far end of an overloaded line, proximity to heavy electrical loads.

Effect: Impeded normal function of connected devices, reduced useful life, overheating, permanent damage.

Over Voltage:

Cause: Energy generation and transportation issues, grid imbalances, being close to improperly set distribution substations, proximity to highly variable electrical loads.

Effect: Impeded normal function of connected devices, reduced useful life, permanent damage.

Brownouts:

Cause: Faults in the generation, transmission and commutation system; sometimes of very short duration, not easy to detect without monitoring equipment.

Effect: Shortened useful life of devices, operational interruptions, loss of information.

Power Outages:

Cause: Faults in the generation, transmission and commutation system; external phenomena: trees, animals, telluric movements, system overload.

Effect: Shortened useful life of devices, operational interruptions, loss of information, inability to operate, stress.

Voltage Variations:

Cause: Connection and disconnection of large loads associated to overloaded, poorly designed or poorly maintained grid.

Effect: Abnormal behavior of connected devices, reduced useful life.
