Intelligent Dielectric Loss Tester
Darui Electric recommends for you:
The intelligent dielectric loss tester is an instrument with an output power of 0.6KVA and a relative humidity of 30% to 70%.
Performance Features
◆Multiple measurement modes are available, including positive/reverse wiring, internal/external standard capacitors, CVT measurement (no external booster needed, the instrument has a built-in power supply), and internal/external test voltage. C1/C2 can be measured simultaneously.
◆High measurement accuracy and good repeatability: The instrument has high test precision, with the basic error of dielectric loss testing less than 0.0005, and the test data repeatability is excellent.
◆In case of high-voltage short circuit or sudden power outage, the instrument can quickly cut off the high voltage and issue a warning message.
◆The high-voltage output socket has no exposed parts, ensuring safety and reliability.
◆High-voltage insulated wire: The insulation level of the high-voltage wire not only involves safety, but its leakage to ground directly affects the accuracy of reverse connection tests. The high-voltage output wire of this instrument is specially made of special materials and can be used directly on the ground. At 10KV output, there is no discharge, no leakage, and no noise to the ground.
◆Large screen with Chinese prompts for operation, RS232 computer interface. The instrument comes with a built-in printer to print test data in time.
◆Anti-vibration performance: The instrument adopts a unique anti-vibration design, which is shock-resistant and not easily damaged. ◆Portable: The volume of this instrument is about 70% of similar products, making it very convenient to carry.
