Coupling device type FP (analogue FPU, FPM, FPMU, FPMR).
Coupling device FP are used to connect equipment high frequency channels of protection equipment and automatic protective devices, equipment of communications and data to the phase of the voltage on the power lines 35 - 750 kV and a ground wire on a "phase-to-earth", "ground wire-to-earth" and " split ground wire-to-earth".
Coupling device cover the entire frequency range of the HF line traps and are designed for peak power HF signal 200 W and 400 W. These devices have a fixed grid frequency ranges, however, at the customer's request can be made any physically realizable combinations of capacitance coupling capacitor, the frequency range and input impedance.
Coupling device has a standard developed by twenty one embodiment presented below. The average operating power of the HF signal is 100 W.
