How Many Years Can a Dielectric Loss Tester Generally Last 
Recommended by Darui Electric
Dielectric Loss TesterAdopting variable frequency anti-interference and Fourier transform digital filtering technology, fully automatic intelligent measurement with very stable measurement data under strong interference. Measurement results are displayed on a large LCD screen, and a built-in micro printer can print the output.
　　Multi-Level Safety Protection Ensuring Personal and Equipment Safety
　　High-Voltage Protection: In case of specimen short circuit, breakdown, or high-voltage current fluctuation, the output can be cut off at high speed via short-circuit method.
　　Low-Voltage Protection: Protection is activated in case of mistaken 380V connection, power fluctuation, or sudden power failure, preventing overvoltage.
　　Grounding Protection: When poor grounding causes the enclosure to carry dangerous voltage, grounding protection is activated.
　The dielectric loss tester uses universal measurement cables. It is recommended to connect this socket using high-voltage wires. High-voltage sockets and high-voltage wires carry dangerous voltage — do not touch high-voltage sockets, cables, clamps, and live parts of the test specimen! Confirm power is off before wiring, and always keep a safe distance during measurement. Ensure zero-resistance connection between the high-voltage wire and the high-voltage end of the specimen; otherwise, it may cause measurement errors or data fluctuations, and may also trigger instrument protection. When using an external standard capacitor, a fully shielded plug connection should be used. This method is commonly used for connecting external high-voltage grade standard capacitors to achieve high-voltage dielectric loss measurement.
　　The fuse holder is integrated with the low-voltage power socket. Use a fuse of the same specification. If the fuse blows again after replacing with a spare, the instrument may be faulty — contact the manufacturer for servicing.
　　Generally speaking, with proper use and maintenance of the dielectric loss tester, its lifespan will be extended, and using it for several years should not be a problem.
