Bundled Conductors For transmission of more power for long distances to load centers Extra High Voltage (EHV) transmission is employed. Implementing Extra High Voltage has advantage of reduction in the copper losses and improves efficiency. However transmission of voltage beyond 300kV will poses some problems such as Corona effect which causes significant power loss and… Read More »
Cable tray / raceway is integral part of any cable management system. Selection of cable tray is very critical because if cable tray size is not sufficient the cables may become damaged due to improper handling and excessive heating etc. On the other hand cable tray supporting system can not be neglected as well since… Read More »
What are the types of line distortions? The distortions occurring in the transmission line are called waveform distortion or line distortion. Waveform distortion is of two types i.e. frequency distortion and phase or delay distortion. How frequency distortion occurs in a power transmission line? When a signal having many frequency components are transmitted along the line,… Read More »
The parameters of a transmission line are Resistance (R), Inductance (L), Capacitance (C) and Conductance (G). Resistance (R) is defined as the loop resistance per unit length of the wire. Its unit is ohm/Km. Inductance (L) is defined as the loop inductance per unit length of the wire. Its unit is Henry/Km. Capacitance (C) is defined as the loop capacitance per… Read More »
Cable Management is a key component of Data Center and Network Management. It refers to an important step during the installation of building services (ie electrical services) and the subsequent installation of equipment providing means to efficiently secure electrical, data, and other cables including the power distribution system. Properly arranged cables increase problem resolution time dramatically.… Read More »
Cable tray system shall be used for laying of MV and LV power, control, instrumentation and special cables in the Power Plant. Cable trays shall be supported on cantilever brackets at specified interval. The trays shall be strong enough to keep the deflection of the fully loaded tray within permissible limits. In general, cable trays run in… Read More »
