Why Renting Computer Equipment Is Better

By and by our continuous technological advancement has improved the standards on what we call the “good life”. A lot of us are now enjoying a life that is more efficient and orderly thanks to the machines and devices that is developed by geniuses all around the globe. However, as technology progresses, the prices of the gadgets and gizmos that we want to make our lives easier gets more and more expensive too. Some examples for these are computer equipments.

Computers and relative devices could contributed hugely to the fast growth and development of a business, which is why nowadays you would see that almost all companies would include them as their asset from the start. A lot of people would say they prefer to buy their own computer devices as a long lasting investment. However, there are some cases wherein computer equipments are better rented that purchased. This is especially true for starting companies who wants to use their capital wisely. This is because if they purchase their own unit, they would have to worry over the budget for technical support. But in rental, a good and reputable company would be able to provide free technical support so that if the renter encounters some difficulties they could just give their rental service provider a ring, and they would be responded instantly.

Also, in urgent situations where you would need your devices transported to other places such as for conventions or temporary moves, it would be better to count on a trustworthy computer equipment rental company than to load your mechanisms in a car and risk damages to it. It reduces the waste of time, energy and finances in the transportation, and it also eliminates the possibility that you might have to get your machines to a repair shop because of some break it may get during the transport.

These are just a few reasons why renting a computer equipment might be a better option. Aside from computers, there are also other technological equipments that are available for rent. Through rental companies, it is now possible to get our hands on these useful tools without worrying too much on the purchasing price and on the cost of its break and tear.

What are Current Transformers?

Electrical equipment that provide a flow of current in the secondary circuit that is directly proportional to the amount of flowing current with its principal circuit is called current transformers. Current transformers are the ones responsible in calculating the current so that the operation of power grid is monitored. This type of electrical instrument is widely used for the purpose of safety in any establishment that utilizes electricity at considerably large amount of voltage.

For metering and protective measures, current transformers are used. This equipment is very important among companies within the giant industry such as electrical power industry. The safety is guaranteed and made even easier through this tool.

How do current transformers work?

Current transformers cut off voltage flow securely so that only lower amount of current would flow, allowing the overloading of electric supply be minimized. This equipment controls electric current by allowing the voltage flow to pass through the windings of wire being wrapped around the well-insulated toroidal core. Current transformers measure the flow current, giving the necessary data to the reader so that the power being used at particular time and length of time would be monitored.

There are some factors that we also need to know about current transformers.

InP Technology To Be Used in Agilent Technologies’ Chipset for Next-Generation, High-Bandwidth Oscilloscopes

Agilent Technologies Inc. had just very recently revealed their technological advancement in the next-generation, high-bandwidth oscilloscopes—the new chipset that could make possible the production of oscilloscopes with true analog bandwidths greater than 16 GHz.

This new chipset will be using indium phosphide (InP) technology. The company claims that this would prove to be better than digital signal processing (DSP) and frequency domain interleaving, or also known as digital bandwidth interleaving or DBI) other bandwidth-enhancing techniques because it doesn’t cause a lot of commotion that hampers the performance and measurement accuracy of the oscilloscopes, a concern that usually comes with the aforementioned techniques. It is somehow also better than the silicon process technologies which are commonly used in the present, which are not truly able to extend the analog bandwidth above 16 GHz range.

The InP technology is said to actually enhance the capacities of the company's InGaP HBT (Heterojunction Bipolar Transistor) IC technology, yielding high-frequency capability with transistor switching frequencies up to 200 GHz. Aside from that, this technology also has better material properties than that with the gallium arsenide (GaAs) process formerly used by Agilent. This is because InP technology gives higher saturated and peak electron velocities, higher thermal conductivity, lower surface recombination velocity, and higher breakdown electric field, which makes the expansion of the present limits in true analog bandwidths.

It is also said that the InP technology enables oscilloscopes to have significantly flatter response at high frequencies, higher measurement accuracy because of the low-noise, nonconductive substrate, and higher reliability due to lower power consumption than what we have today.

It seems that the 16 GHz limit would just be the first step for the company. According to Jay Alexander, vice president and general manager of Agilent's oscilloscope organization, "Our first oscilloscope family offering this new high-speed chipset will start at 16 GHz bandwidth." They would be introducing this high bandwidth family in the first half of 2010.

Electricity Safety Tips

Electricity is a powerful two-edged tool. While it’s true that we have been highly benefited by its energy as it is used in our everyday lives, it also has a great potential for destruction when we don’t exercise care and caution around it. So here are some of the basic safety tips to follow in order to avoid electrical accidents.

One main thing you should do is to make it a habit to switch of unused appliances or equipments. This is not only a safety tip but is also a suggestion that could help lessen consumption of energy. Also, if you notice that a cord is unusually hot, unplug it immediately from the outlet, and then have your qualified electrician check and mend any faulty wiring as soon as possible. If possible avoid plugging on areas where wires can get tripped on. And make sure that your power cords are not faulty or damaged, or if they are, let your electrician do the proper repairs.

See if there is discoloration or burn marks in your appliances and refrain from using it without having it checked by a competent technician first. One thing you should also remember when buying your appliances is to make sure that they conform to the safety and quality standards. Do not buy devices that are cheaper, and check if what you bought have been recalled due to manufacturing problems. Follow the instruction manuals when using them. It would also be wise to conduct a regular PAT test for your equipments. This test is required as a safety regulation in workplaces.

Electricity should not be taken lightly just because it has been a part of our daily existence already. Even one act of negligence might cause unexpected tragedies. Following these safety tips would help. But being cautious is still the best safety procedure.

Facts about Insulation Tester

When doing projects such as home renovation, it is important to use insulation tester. The reason is that your overall safety is ensured by using such device. Prior to adding soundproofing material, major repair projects where electrical system quality is not known, and installing wallpaper, insulation testing should be done. Leaking current would result if there is insufficient insulation. Obviously, leaky current is the common culprit of hazardous events such as fire.

Insulation testers are one of the easy-to-use technology products; it can be used by a novice. This product is usually performed even without the help of a technician or an expert.

This product works with the application of DC voltage to the insulation system. The current that flows through the DC voltage is measured. Then, the results of the test would tell if there is or nothing wrong with your home electrical system. Current leak is accurately detected with this device.

There are several kinds of testers in which the very common ones are portable one. They come in 50, 100, 250, 500, and 1000 volts. Of course, you must not overlook the principle of parallelism; you have to use the right tester for the right system. This means that if you are going to test an electrical system with high voltage, you have to use testers that are capable of holding such current; if you are going to test a low voltage system, you have to use low voltage testers.
