The Transformer Dielectric Loss Tester is a fundamental method for insulation testing that effectively detects overall damp deterioration and local defects in the insulation of electrical equipment. It is widely used in electrical manufacturing, equipment installation, handover, and preventive maintenance testing. Measuring the dielectric loss of transformers, mutual inductors, reactors, capacitors, bushings, and lightning arresters is a basic technique for assessing their insulation performance. The dielectric loss tester has overcome the limitations of traditional bridge measurement methods by adopting frequency conversion power supply technology. It uses a microcontroller and modern electronic technology for automatic frequency conversion, mode/number conversion, and data processing. The tester features strong anti-interference capabilities, fast testing speed, high precision, automatic digitization, and easy operation. The power supply uses a high-power switching unit that outputs pure sinusoidal waves at 45Hz and 55Hz. It also includes automatic voltage regulation, providing up to 10 kV of voltage. The tester automatically filters out 50Hz interference, making it suitable for large field tests in environments with high electromagnetic interference, such as substations. The Transformer Dielectric Loss Tester is widely used in the power industry for testing transformers, mutual inductors, bushings, capacitors, lightning arresters, and other electrical equipment.
