LMU is a composite unit consisting of Drain Coil, Isolation transformer with Lightning Arrester on its both the sides, a Tuning Device and an earth switch. Tuning Device is the combination of R-L-C circuits which act as filter circuit. LMU is also known as Coupling Device. Together with coupling capacitor, LMU serves the purpose of connecting effectively the Audio/Radio frequency signals to either transmission line or PLC terminal and protection of the PLCC unit from the over voltages caused due to transients on power system.

What is the function of coupling capacitor in substation?

A coupling capacitor in substation is used for power line communication purposes. It used after the wave trap. The capacitance ranges from 2200pf to 10,000pf. It offers very low impedance to high frequency carrier signal and allows them to enter the line matching unit and offers a very high impedance path to low frequency signal or wave and blocks it for reaching the line matching unit. In short, it allows only those frequencies needed for communication purposes.
