At Tecnomedida, we continue to strengthen our commitment to technical excellence and energy sustainability through specialized projects that enhance the reliability of electrical systems across the country. Below, we share some of our most recent projects, where precision, safety, and performance took center stage:
What is ultrasound analysis?
Ultrasonic analysis in electrical equipment maintenance involves
in the detection and observation of high-frequency sound waves (over
20 kHz) emitted by electrical equipment when it malfunctions
incipientes.
Although these sounds exist, they are inaudible to the human ear, so
Ultrasonic transducers are used to detect them, converting these waves
into audible or visual signals that technicians can interpret. Thank you
With this technology, it is possible to take action before the problem becomes
a serious flaw.
Which defects produce ultrasonic sounds?
Electric arcs and partial discharges: In electrical systems, the
Insulation is one of the most critical factors in ensuring a
safe and reliable operation. However, over time and
Under demanding operating conditions, this insulation can
deteriorate due to aging, moisture, dirt, overloading, or
faulty connections. When this happens, certain phenomena occur
such as electric arcs and partial discharges (PDs)
1. Partial discharges: These are localized micro-discharges that
occur within deteriorated insulation or in its
surfaces. Although they are low in intensity, they are a clear sign of
that the insulation is failing.
2. Electrical arcs: These occur when insulation failure is
more severe, allowing the current to jump between two
conductors through the air or damaged material. This
This phenomenon causes extreme heat, fire hazards, and damage
immediately to the team.
Abnormal vibrations: In rotating electrical equipment with motors,
generators, pumps, and bearings; failures rarely occur in
suddenly. In most cases, the deterioration begins with
small mechanical vibrations that, although imperceptible to the
to the human ear, they emit clear, detectable ultrasonic signals.
These abnormal vibrations are the first sign of trouble
such as: shaft misalignment, imbalance in rotating components,
wear or damage to bearings, and excessive friction or a lack of
lubrication.
Through ultrasonic contact sensors, the
vibrations emitted by the equipment in operation. These signals, are
transformed into graphs and spectra that show the intensity and
the type of vibration and audible signals that allow the technician
to understand the condition of the equipment.
Where is ultrasonic measurement applied?
Ultrasound technology is applied in different equipment within
electrical installations such as:
● Medium and high voltage board.
● Power transformers.
● GIS Grid
● Power switches.
● Electric motors and generators.
● Transmission and distribution lines.
Benefits of ultrasound analysis
Ultrasonic testing is not just a tool for detecting defects
hidden, it is a comprehensive maintenance strategy that provides real value
to the operation of any company.
Among the main benefits are highlighted:
● Safety: The early detection of arcs, partial discharges and
gas leaks, significantly reducing the risk of fires,
explosions and electrical accidents.
● Operational continuity: By identifying emerging problems, one
they avoid unplanned stops and maintenance is scheduled
efficiently.
● Cost savings: Repairing equipment on time is always less
costoso que reemplazarlo tras una falla enorme.
● Confiabilidad del sistema: Prolonga la vida útil de transformadores,
motors and panels guaranteeing optimal and stable performance.
● Environmental responsibility: The detection of gas leaks builds
to the reduction of environmental impact and compliance with regulations.
