Neutral earthing in Electrical System

Neutral earthing in Electrical System is the Very important for Equipment like Transformers, Generators, etc. Earth (Ground) has very low resistance. Earth (Ground) big conducting medium.
Neutral Earthing is always connected with 3-phase star point of the Transformer. Generator’s star point is also connected with Neutral Earthing. In Bipolar HVDC substation Neutral Point is also Earthed/Grounded.
Neutral Earthing has so many Advantages. Because of Neutral grounding earth fault protection becomes easier. Neutral Earthing draws unbalanced current in case of system gets unbalanced. By measuring that neutral current protection can be applied. Neutral grounding provides a very stable neutral point to whole system. As the Neutral is grounded, Phase to Earth voltage will not rise. Neutral Earthing can also reduce insulation failure.
So, Neutral earthing really helpful for system.

What is CSD (Controlled Switching Device) in Electrical System

Definitions CSD (Controlled Switching Device): A device that is installed at the relay and control panel to overcome the transient behaviour of voltage and current during switching. This device synchronizes the switching of each pole of the circuit breaker according to the zero crossing of the corresponding phase. This device is also known as a phase synchronizing device, or PSD for short. Requirement When we switch off an online circuit breaker to disconnect an inductive load, we ideally want to interrupt the current of the system at the zero crossing of the current waveform. However, this is practically impossible to achieve. In a normal circuit breaker, the current interruption may occur near the zero crossing point, but not exactly at it. Since the load is inductive, this sudden interruption of current causes a high rate of change of current (di/dt), which results in a high transient voltage in the system. In low or medium voltage power systems, this transient voltage during circui...

Right Of Way / Way Leave Clearance for various Electrical Power Transmission Line

Width of maximum right of way permitted as per forest conservation act ‘1980 and its subsequent amendment dated 25 th October, 1992, are as per Table 1.  Researches are being carried out for further optimizing the Right of Way. Guidelines of forest environmental rules shall be followed to avoid excessive tree cutting i.e. all the trees should be cut from root level in the 3 m corridor below each line conductor / earth wires.  In the balance corridor, trees branches are only to be lopped to attain the specified clearance as per Table 1. Table 1  – Guidelines for Right of Way as per forest conservations act 1980 and subsequent amendment dated 25 th October, 1992 Line voltage (kV) 66 110 132 220 400 500 HVDC 765 Row width (Meter) 18 22 27 35 52 52 85 Electrical clearance:   Electrical clearance while power lines crossing each other. In case of power line crossings, minimum clearance between lowest conductor of line and ground wire / top conductor of ...

Roles and Responsibilities of SLDC- State Load Dispatch Center in India

As per section 33 of Electricity Act – 2003 (Central Act 36 of 2003), SLDC-State Load Dispatch centers performs:- SLDC- State Load Dispatch Center suppose to carry out following functions or Roles and Responsibilities of State Load Dispatch Center. Scheduling: All Open Access users (excluding wind and mini hydel and generating stations having total capacity not less than 5 MW and up to 15 MW opting for injection under UI) that are connected to the Grid shall schedule and dispatch according to instructions given by SLDC. The methodology of scheduling shall be according to provisions of Gujarat State Grid Code and Clauses 26 and 44 of GERC Tariff Regulations. Gaming: SLDC should see that no gaming is done while declaring capacity by generators. Energy Accounting: A State Energy Account, for the billing and settlement of ‘Capacity Charge’, ‘Energy Charge’, ‘UI Charge’ and ‘Reactive Charge’ shall be prepared by the SLDC. The SLDC...
