Transformer Tan Delta Tester

Dielectric damage measurement is a fundamental method in insulation testing, which can effectively detect both overall damp deterioration of electrical equipment insulation and localized defects. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive testing. The dielectric damage measurement of transformers, reactors, capacitors, casings, and lightning arresters is the most basic method for assessing their insulation performance.

This method breaks through the traditional bridge measurement technique by using frequency conversion power supply technology, a microcontroller, and modern electronic technologies for automatic frequency conversion, analog/digital conversion, and data processing. It offers fast testing speed, high accuracy, automatic digital operation, and ease of use. The power supply utilizes a high-power switch, outputting 45Hz, 50Hz, and 55Hz pure sine waves with automatic voltage regulation, providing up to 500V. An automatic filter eliminates 50Hz interference, making it suitable for substation electromagnetic interference field tests.

It is widely used in the power industry for testing transformers, reactors, casings, capacitors, lightning arresters, and other equipment.

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.
