Product Description


Insulating dielectric loss measurementof transformers, transformers, reactors, capacitors, and bushings, surge arresters is a very basic test method can effectively find the overall damp insulation deterioration and local defects of electrical equipment. It is widely used in electrical manufacturing, electrical equipment installation, transfer and preventive tests.

WGSL-4C Automatic Frequency Dielectric Loss Tester bridge broke through the traditional measurement, adopting variable frequency power supply technology, SBC and modern electronic technology of automaticly frequency conversion, A / D conversion and data operations; It has the characters of good anti-interference ability, fast test speed, high precision, fully automatic digital and easy to operate; It has a high-power switching power supply to output 45Hz and 55Hz pure sine wave, providing up to 10 kV voltage; It can automatically filter out 50Hz interference suitable for testing at substations and other fields of large electromagnetic interference.

Measurement modes
UST (Ungrounded specimen test)
This test is made when the specimen can be insulated from ground
The test is often used to reduce the effect of stray capacitance
Losses to ground and to reduce the effect of interference pickup from nearby
Energized apparatus.

Typical test specimen include the primary to secondary winding insulation in high
Voltage transformers and measurements on HV bushings with a capacitance tap.

GST (Grounded specimen test)
This is the most frequent used test connection and involves all insulation between
The high voltage conductor and ground. Typical test specimens include transformer
Windings to tank and core, circuit breaker assemblies, coils of rotating machines, etc.

GST-g (Grounded specimen test with guard )
This test is used to separate the total values of the GST into separate
Parts for better analysis. Often this test is used with the GST to confirm the test
Readings made using the UST
