QS30 is designed for highest precision determining the capacitance and dielectric dissipation factor tand 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.
The system performs manual measurement of Dissipation Factor (tan δ) & Power Factor (cos φ)and Capacitance. It’s designed to help you modernize your testing facility at an affordable price and, it’s simple to operate.
Technical Index
·The capacitance ratio Cx/Cs (when the rated ratio is 1:1) is 0 ～ 1.111110. The step is 0.000001. The ratio (K) range includes ten steps: 1000, 500, 200, 100, 50, 20, 10, 5, 2 and 1. The measuring range of capacitance depends on the capacitance of the standard capacitor Cs, i.e. Cx = Cs ·K·(Cx/Cs)
