YL Series HV Standard Capacitor
Gas insulated Standard Capacitors is an indispensable instrument in every modern high- voltage laboratory and widely applied to important test field.The SF6 insulated standard capacitor is used as standard capacitor in measuring bridge Circuits to measure the capacitance and the dielectric loss Factor tanδ, Further-more, meanwhile used as high- voltage capacitive divider to measure the voltage of loop.
