Dielectric loss measurement is a very basic method in insulation test. It can effectively detect the whole damp deterioration and partial defects of electrical equipment insulation. It is widely used in electrical manufacturing, installation of electrical equipment, handover and preventive testing. Measurement of dielectric loss of transformer, transformer, reactor, capacitor, bushing and arrester is the most basic method to measure their insulation performance.PS-FA Capacitan&Tan-Delta tester breaks through the traditional bridge measurement mode by adopting frequency conversion power supply technology, using single chip computer and modern electronic technology to automatically convert
frequency, analog-to-digital conversion and data operation; it achieves strong anti-interference ability, fast testing speed, high accuracy, automatic digitalization and easy operation; the power supply adopts high-power switching power supply, and outputs 45Hz and 55Hz pure sinusoidal wave. Automatic pressurization can provide up to 10 kilovolts of voltage; automatic filtering of 50 Hz interference, suitable for field testing of large electromagnetic interference in substations. It is widely used in dielectric loss measurement of transformer, transformer, bushing, capacitor, arrester and other equipment in power industry.
