Calibration is a crucial practice for accurately assessing electrical equipment, ensuring that the measured quantities are consistent. The DP HVEX Calibrator serves as an essential tool in this process, adjusting and verifying the performance of instruments involved in these tests.

The calibration of measurement equipment is critical to ensuring the accuracy and reliability of analyses conducted across various industrial sectors, especially in the field of electricity. One key aspect of this process is evaluating partial discharges, a phenomenon that can indicate incipient failures in transformers, generators, motors, and other electrical components.

According to IEC 60270 standard, partial discharges are "localized electrical discharges that only partially bridge the insulation between conductors." Typically, they result from a localized concentration of electrical stress in the insulation or on an insulating surface. These discharges often manifest as pulses lasting less than 1 microsecond.

In essence, partial discharges can be defined as incomplete breakdowns between different potentials, generating small electrical sparks that occur within the insulation of electrical equipment when subjected to high voltages. These discharges can indicate issues such as micro-cracks, impurities, or wear in the insulation material, which, if undetected and unaddressed, could evolve into catastrophic failures. The main features of DP formation are the presence of deposits, cavities, foreign bodies, heterogeneous dielectrics, tracking formation, material erosion and surface problems.

Calibration is the process of adjusting and verifying the accuracy of a measuring instrument by comparing the results it provides against those of a known and accepted reference standard. The goal is to ensure that measurements taken by the instrument are accurate and reliable, providing consistent results over time.

To accurately identify and monitor partial discharges, it is essential to use properly calibrated measuring equipment. Calibration of these instruments ensures that they operate within technical specifications, delivering reliable and accurate results.

Calibrating the measurement of partial discharges in electrical equipment is essential for conducting tests with satisfactory performance. Therefore, for this task, calibrators are required as established by the standard NBR IEC 60270.

The HVEX DP Calibrator is an advanced portable device specifically designed for calibrating partial discharge measurement instruments. With the capability to generate bipolar pulses at various intensities and frequencies, this calibrator is ideal for adjusting and verifying the accuracy of devices used in electrical equipment.

Its key benefits include versatility, reliability, and ease of use, as well as ensuring predictive maintenance by helping to identify potential failures before they cause significant damage.

Investing in regular calibration using advanced technologies like the HVEX DP Calibrator not only optimizes operational efficiency but also extends the lifespan of electrical equipment. With accuracy assured by proper calibration, companies can perform preventive maintenance more effectively, reducing costs and minimizing operational risks.
