HVAC Transmission System (Electric Power Transmission Lines)

Introduction to HVAC Transmission System

The increased demand of electricity needs more generation of electrical power. As the generation takes place at remote places, an efficient distribution system is necessary. The problems of AC transmission particularly in long distance transmission has led to the development of DC transmission.

HVAC Transmission system can be divided into two parts:

(a) Transmission System

(b) Distribution Sysyem

Each part is again subdivided into two parts:

1. Primary Transmission

2. Secondary Transmission

Generation and transmission now a days is almost exclusively three phase. The secondary transmission is also three phase whereas the distribution to the customer may be three phase or single depending on the requirement of the consumer.

Primary Transmission

in fig the central station CS generates power using three phase alternators at 6.6 or 11 or 13.2 or 32 kV. The voltage is then stepped up by suitable three phase transformers, to 132 kV as shown.

Such a high voltage of transmission requires conductors of smaller cross section which results reduction in the cost of copper or aluminium.

However the cost of insulation increases. The transmission voltage is therefore determined by economic considerations. Higher transmission voltage also reduces the line losses and improves the efficiency.

The three phase three wire overhead high voltage transmission line gets terminated in the step down transformers in a sub station known as Receiving Station (RS).

Receiving station is usually situated outside the city to ensure safety. Here the voltage is stepped down to 33 kV from 132 kV.

Secondary Transmission

From The receiving station, power is then transmitted at 33kv by underground cables located at various points in the city. This is known as secondary or low voltage transmission. At substation this is further reduced from 3kV to 3.3 kV, using step down transformers.

Primary Distribution

The output of substation at 3.3 kV can be directly given to a customer whose demand exceeds 50kVA using special feeders. This is primary distribution.

Secondary Distribution

The secondary distribution is done at 440 or 230 V. The reduction in voltage level from 3.3 kV to 440/230 V is done by the step down transformers at the distribution substations.

The most common system for secondary distribution is 440/230 V, three phase, four wire system. The single phase residential load is connected between any one line and the neutral where as three phase 440 V , motor load is connected across thee phase lines directly. The standard frequency for a.c. working is 50 Hz in India and 60 Hz for U.S.A. For single phase traction applications, frequencies as low as 25 or 16.67 Hz are also used.

PEX Pipe Problems

The age of metals is passe, at least when it comes to household furnishing materials. Polymers, plastics and other synthetic materials are replacing metals everywhere. One such new material that is rapidly replacing copper as a plumbing pipe material is PEX (Cross-Linked Polyethylene).

About PEX

PEX is a modified form of polyethylene. The cross-linking of polymers within polyethylene strengthens the material. Due to the cross-linking, it can now withstand a wide variation of temperatures, from freezing point till about 200 degree Fahrenheit. It is also reinforced to withstand chemical corrosion and is flexible in nature.

Alternative Cheaper, Green Paving Using Polymer by Dan Banici

Will polymer replace asphalt?

The asphalt on our roads is perceived by many like the gas in our tanks. We simply consider it indispensable. The truth is that asphalt can be replaced, as the booming Concrete Paving industry has proven to us already. This is not a finger pointing article, far be it from me. I would like nothing more than to see all asphalt professionals get more involved with alternative technologies, since they already have much of the equipment necessary, and it helps them build and repair more road, more efficiently and more competitively.

Environmental issues of asphalt:

Asphalt makes an excellent road surface, there is no denying it. However

Solar Power: What About Lightning?

I'm an obvious fan of solar power, and after a few disasters I've come to appreciate preparation. One of the most expensive disasters to occur to us was a nearby lightning strike.

I wasn't home at the time, so it was a surprise when I came home the house was dark. I grabbed my flashlight and hurried to see what had happened. It was sad. My beautiful Trace charge controller was a crispy critter, and both of my TR3624 inverters were suitable for pictures only. No power out! My panels survived, my wind turbine was just fine, but my inverters were dead.

Well after a suitable mourning period (2 or 3 minutes), I fired up the generator, packaged up my dead inverters, and sent my them

They cannot force the parent to return the child or children because there is no order telling them which party has legal or physical custody. So, talk to some child custody lawyers. Orange County, California attorneys can file an immediate hearing to get a Court order.

If there are reasons to persona injury lawyers suspect that the minor child or children are being physically harmed or if threat of physical harm is evident, the Court will hear the case in an Exparte hearing. Which means little or no notice is required to the other party and the hearing can be put on the Court's calendar the next day.
