How Unplanned HDD Reducing Future Facilities?

Unplanned HDD Reducing Future Facilities

Unplanned Horizontal Directional Drilling Works are Reducing Future Facilities for the Utilities Authorities in Dhaka City

Unplanned Horizontal Directional Drilling (HDD) in Dhaka reduces future utility capacity by causing chaotic, unmapped congestion in the underground space. Lack of coordination leads to high-risk installations that damage existing infrastructure, increase service installation costs, and restrict space for future development. 

Challenges for Underground Distribution in Dhaka City

 

Underground Power System Distribution in Dhaka City is a Big Challenge 

Dhaka faces high capital costs, extreme population density, very limited street footprint, waterlogging, scarce equipment space, existing utility conflicts, and poor inter-utility coordination — each of which raises technical, financial, and institutional barriers to rolling out a modern underground distribution network.

What is the Function of an Earthing or Grounding Transformer?

 Earthing or Grounding Transformer

Generally, an Earthing or Grounding Transformer is not a three-phase transformer, but a single-phase transformer with the primary (HV end) rated voltage equal to the system phase-to-neutral voltage and the secondary (LV end) rated voltage of either 240V or 11oV.

To avoid any switching transient in the Transformer primary of the transmission system, or a big noise may damage the Transformer. To avoid such spurious signal, grounding is provided in the primary. The grounding also affects third harmonics from the switching transient.

What is an Instrument Transformer and how does it work?

The Instrument transformers are the same as other conventional transformers, but different it is just high-accuracy class electrical devices. Instrument transformers are actually used to isolate or transform voltage or current levels for using metering or controlling signals. 

Operating the instruments for controlling the system or measuring the high-level voltage or current, the instrument transformers are used to decrease the voltage or current level to the measuring level for safely isolating secondary control circuitry from the high voltages or currents.

Electrical Substation Equipment: Insulator and Its Functions

Electrical substations play a critical role in the transmission and distribution of electricity from power generation plants to consumers. Insulators are an essential component of electrical substations, and their primary function is to provide electrical isolation and mechanical support to various equipment and conductors within the substation. Here's a closer look at insulators and their functions:

Vital Substation Equipment Insulator and Its Different Functions

Electrical Isolation: One of the main functions of insulators is to prevent the flow of electrical current between different conductive elements in the substation. These conductive elements could be overhead power lines, busbars, or other live equipment. By creating a barrier between conductive parts, insulators prevent unwanted electrical arcing or short circuits, ensuring the safe and reliable operation of the substation.
