APPLICATION  HCL2876 Manual C, L & tan δ/ cos ϕ precision measuring bridge is designed for determining the capacitance and dielectric dissipation factor of liquid and solid insulants, cables, capacitors, line transformers, generators, motors, bushings etc. Furthermore it can also be used for power loss measurement on shunt reactors or similar apparatus. This system is suitable for both low and high voltage measurement at line frequency. Measurement reports can be printed. This measuring equipment has been specially developed to maximise efficiency in production and quality control environments. Its outstanding accuracy also makes it suitable for laboratory and research applications.
