Abychom splnili provozní požadavky energetické soustavy, musíme klást důraz na izolační vlastnosti a provádět izolační zkoušky. Před uvedením do provozu nebo při dokončení návrhu výrobku je nutné použít standardní zkušební metody, aby bylo zajištěno, že izolační vlastnosti vodičů a kabelů splňují konstrukční a provozní požadavky.

Prostřednictvím zkušebního testu pro elektrické zkoušení vysokonapěťových rozvaděčů lze komplexně zkontrolovat výkonnostní parametry zařízení, a to včas zjistit případné nedostatky a skryté nebezpečí, aby bylo zajištěno, že zařízení bude po uvedení do provozu stabilně a spolehlivě fungovat.

This article mainly discusses the test methods of oil-impregnated paper-insulated cables, plastic-insulated cables and cross-linked polyethylene cables, and the common electrical tests include DC withstand voltage and leakage current tests, VLF withstand voltage tests, Power frequency AC resonance withstand voltage testing , partial discharge tests and so on.

Rated frequency withstand voltage is the maximum voltage that electrical equipment or its insulation system can safely handle during normal operation at the rated frequency (such as 50Hz or 60Hz). Under this voltage, the equipment can operate normally without experiencing insulation breakdown or other failures.

we will analyze the differences between transformer type testing and transformer factory acceptance testing in terms of standard basis, test items, parameter requirements, and criteria for passing judgment. This analysis aims to provide valuable references and guidelines for the design, manufacture, acceptance, operation, and maintenance of transformers.

A battery charger discharger is an advanced piece of equipment designed to perform two critical tasks: charging a battery to its full capacity and discharging it to measure performance, capacity, and other key parameters. These systems are commonly used for testing and maintaining batteries in various applications, ensuring their optimal operation and longevity.

Battery test equipment is essential for maintaining the reliability and performance of batteries in backup power systems. These tools play a crucial role in ensuring that batteries function as expected during critical moments and remain in optimal condition throughout their lifecycle.

The dielectric strength test for transformer insulating oil is an electrical performance evaluation defined as the measurement of the maximum voltage that the oil can withstand between two electrodes under specified test conditions before electrical breakdown occurs
