Measuring the dielectric loss factor at the equipment's actual operating voltage provides a more accurate assessment of its insulation condition. However, conventional dielectric loss testers with built-in high-voltage power supplies typically have a maximum output voltage of only 10 kV, which often falls short of the equipment's operating voltage. To meet the need for measuring the dielectric loss factor of high-voltage equipment at operating voltage, our company has developed a series of high-voltage dielectric loss factor testers (referred to as \"high-voltage dielectric loss testers\").\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003eThis series utilizes an external high-voltage power supply, allowing users to flexibly configure the test voltage.
