Automatic Dielectric Loss Tester
Darui Electric recommends for you:
The English name of the Automatic Dielectric Loss Tester is: Anti-jamming Automatic Different Frequency Dielectric Loss Tester. The Automatic Dielectric Loss Tester is an advanced instrument for measuring dielectric loss and capacitance, used under power frequency high voltage to measure the dielectric loss and capacitance of various insulating materials, insulating bushings, power cables, capacitors, transformers, and other high-voltage equipment.
Features
◆ Simple operation, Chinese display, printing
◆ Convenient use, no conversion needed
◆ The different frequency dielectric loss tester comes with built-in high voltage, strong anti-interference capability, and short test time
◆ This instrument has an automatic detection function, such as automatically entering reset state and executing voltage regulator return to zero upon startup.
◆ Adopts a miniature TPU-A panel printer for automatic printout.
◆ According to user needs, it can change the number of tests, stirring and settling time, sound and light control reminders, continuous printing and non-printing.
◆ This instrument uses fully automatic magnetic stirrer to eliminate unevenness and bubbles in oil samples.
Characteristics
1. The fully automatic anti-interference different frequency dielectric loss tester can accurately measure under strong electric field interference due to frequency conversion technology.
2. The instrument uses Chinese menu operation, and the microcomputer automatically completes the entire measurement process.
3. This instrument is also suitable for measuring tgδ and capacitance of high-voltage electrical equipment in workshops, laboratories, and scientific research institutions.
4. This instrument can use positive or reverse wiring methods to measure high-voltage electrical equipment that is ungrounded or directly grounded. It can also measure the tgδ of capacitor voltage transformers and the capacitances of main capacitors C1 and C2.
5. The instrument is equipped with a built-in high-voltage step-up transformer and adopts safety protection measures such as zero-crossing switching and lightning protection. During the test, it outputs high voltage of different levels from 0.5KV to 10kV, making operation simple and safe.
