Tan Delta, also known as dielectric dissipation factor, is a measure of the energy lost in an insulation system when AC voltage is applied.

An Oil BDV Tester provides a fast and valuable indication of an insulating liquid’s ability to withstand electrical stress under a defined test method. The reliability of that indication depends on much more than the maximum tester voltage.

Dealing with sudden cable failures after commissioning is a nightmare

Utilities use planned VLF withstand or diagnostic work to support acceptance, maintenance prioritization, and investigation of shielded distribution circuits. Equipment selection and interpretation must also account for cable voltage, capacitance, waveform, condition, and the approved procedure.

A battery discharge tester is an electronic load device used to measure the true capacity of backup batteries. It pulls a constant current from the battery until a cutoff voltage. This test finds dead cells and proves the battery can support your critical systems during a real power outage.

This article explains the measurement principle, GST/UST/GSTg connections, field-testing procedures, abnormal-result troubleshooting and practical solutions for different transformer-testing environments.

You test transformer bushings to find deadly moisture and stop explosions. Use the right C1 and C2 connections, read the spikes correctly, and always replace failing parts immediately.

Maintaining high-voltage circuit breakers requires more than just mechanical checks; rigorous SF6 gas analysis is critical. A standardized maintenance checklist focusing on dew point testing, leak detection, and purity analysis ensures compliance with IEC 60480 standards.

El control eficaz de la humedad en el SF6 es imprescindible para la seguridad y la vida útil de los conmutadores aislados con gas. Un medidor de punto de rocío de SF6 funciona como un sistema de alerta temprana fundamental, ya que mide con precisión las trazas de humedad para evitar la formación de ácidos altamente tóxicos durante la formación de arcos eléctricos.

Performing an AC resonance test on XLPE cables requires careful planning and strict execution. The success of your high-voltage testing depends entirely on a correct setup and precise tuning.
