Introduction

The standard capacitor is used to test insulation dielectric loss on-site, in laboratory, and in the wild. Specific high voltage standard capacitor could be made on request, such as 500PF-1000PF capacitors.
YL（5KV-1200KV）- (50PF-100PF）standard capacitor could be placed horizontally during
transportation. Technical parameters as below:
