Thermography is a technique that allows accurate temperatures to be measured at a distance and without the need for physical contact with the object to be studied.
By capturing the infrared radiation of the electromagnetic spectrum using thermographic cameras, the radiated energy is converted into information about the temperature of the object.
Thermography is commonly applied for:
The study of distribution systems can alert to energy losses caused by poor insulation, breakage or incorrect gearing.
Through a study of the building envelope we can optimize the air conditioning system with the consequent energy savings by obtaining more information on the condition and effectiveness of the enclosures.
A Power Quality Analyzer monitors all unwanted electrical phenomena affecting the load or the power supply source.
Power quality defects can be classified into five types:
The analysis can be used to reduce energy consumption associated with electrical imbalances and to identify problems in the network generated by the machines and equipment connected to other applications.
SCI analyzes the quality of the power supply to locate, predict, prevent and solve problems in distribution systems and electrical installations quickly and safely.
Dielectric strength or electrostatic stiffness is the limiting value of the electric field strength at which a material loses its insulating property and becomes conductive.
SCI performs this test for output ranges 0-75 kV DC with the use of a dielectrometer.
High and low voltage cables in electrical installations and equipment have insulation characteristics that allow their safe operation.
These insulation characteristics can be modified with the passage of time and use, which can generate electrical leaks that can cause occupational accidents and interruptions in production processes.
This section specifies the controls and inspections carried out by SCI technicians on High and Low Voltage electrical installations, both prior and periodic.
They measure the insulation of high and low voltage cables in order to detect the degree of degradation in the insulation characteristics.
The Insulation Measurement in High and Low Voltage Cables should be performed after the measurement of the dielectric strength, since the values obtained are directly related.
Step and Touch Stress Measurement is the best method to determine the potential risk of personal injury.
For this measurement, an overhead line or cable is used to inject current into the remote grounding system to cause a voltage drop.
In this way, it is possible to measure touch voltages in the fence surrounding the substation, or in other areas where there is a risk of contact.
SCI performs these tests in substations, transformer stations and on high-voltage line supports.
