MOEORW- WHVA80 80kV VLF Tester With Tan Delta
The MOEORW-WHVA80 VLF Tester With Tan Delta is suitable for insulation withstand voltage and dielectric loss testing of large capacitor electrical equipment. It is a dedicated device for preventive insulation testing of electrical equipment.
VLF Hipot Tester With Tan Delta can perform handover and preventive testing of 35kV and below power cables, large and medium-sized generators/motors, and power capacitors.
Product Introduction
Our company's new generation of 0.1Hz VLF dielectric loss high voltage generators utilizes the latest power electronic components and microcontroller technology, further reducing the size and weight of the equipment. It features user-friendly operation, more stable performance, and overcomes the shortcomings of the first-generation mechanical step-up transformers, such as short lifespan, high failure rate, and large size. Years of practical experience and extensive user feedback have demonstrated that this series of ultra-low frequency high voltage technologies is leading nationwide and offers excellent value for money!
