The digital insulation tester is an instrument used to check the condition of the electrical insulation of cables, motors, windings, systems and equipment. The test makes it possible to assess how effectively the insulation opposes the flow of current between conductive parts, helping identify conditions that may require further technical investigation.
This type of check is useful during preventive maintenance, servicing, testing and periodic inspections on electrical systems. An inadequate insulation value may be associated with moisture, deterioration of insulating materials, contamination, wear or damage to cables and components.
The digital insulation tester allows tests to be performed with selectable voltages of 250, 500 and 1,000 V, making it possible to adapt the check to the type of circuit, the component to be tested and the required test plan. The test voltage should be selected in accordance with the characteristics of the system and the items being checked.
In addition to insulation testing, the instrument can measure AC/DC voltage, resistance and continuity. It therefore combines functions useful for preliminary electrical checks and inspections on lines, circuits and components, without the need for several separate instruments.
The electrical insulation tester can be used on cables, motors, windings, electrical tools, equipment and panels when the integrity of insulation between conductors or to earth needs to be checked. It is also useful for checks on lift systems, where it can support the inspection of cables, circuits and electrical components before or during technical verification activities.
The Hold and auto-ranging functions make it easier to read values during the check. The backlit display also makes viewing more convenient in technical rooms, machine rooms and areas with reduced lighting.
Calibration report available on request, to accompany the digital insulation tester with metrological documentation useful for internal checks and for monitoring its status over time.
