6 Smart Grid Functions of Intelligent Protection Relays

Intelligent electronic devices today are able to carry out an astonishing array of powerful functions. Through rapid evolution, intelligent modules are consistently added and these advances are game changing in utilities development. Intelligent protection relays can protect, monitor, control and measure grid conditions in real time all the way through the grid to distribution substations. Through device writing functions and relay system settings, values can be changed and separately stored.

Protection

An intelligent protection relay is first and foremost an intelligent electronic device that uses a microprocessor. Performing around 5-12 protection functions, these microprocessors detect faults and performs protective tasks like over-current release and reclosing using the relay inputs of current and voltage signals received via transformers. Extensive protection of three-phase lines is possible. Data is permanently stored, even if power is lost.

Measurement

Today’s intelligent protection relays perform the accurate measurement of a number of factors related to current and voltage. Measuring current, voltage, apparent power, active power, reactive power, power factor and frequency, and even phasors, these digital relays are able to measure and respond protectively according to presets programmed in when the relay is first connected. Accurate readings and set responses enable the grid to perform in more predictable ways.

Monitoring and Control

Advanced monitoring and diagnostics are possible using intelligent protection relays. This level of effective monitoring and control has effects throughout the network. Radical changes in security, reliability and grid efficiency is possible through these highly automated processes that can be verified remotely in real time. Using these relays, outages can be reduced and fault areas limited and rapidly cleared from the grid.

Interlock Logic

Interlock schemes are usually hardwired with interlock status contacts to prevent unsafe switching when the intelligent protection relays operate in manual modes. These interlock schemes are state stable, failsafe and robust. Logic-based interlocking operations are performed via computer using buttons, switches or toggles on a video or panel interface.

Self Diagnosis

Intelligent protection relays can self diagnose. For events to be recorded and quick responses to faults made possible, the relays are fitted with a self diagnostic function. This allows the permanent monitoring of operation states and standard follow up activity once any problem sensed by the intelligent protection relay system. Messages will be displayed on an LED screen or panel, enabling response by dedicated personnel or in some instances, automated self healing.

Communications

The communications capability of intelligent protection relays allow for high communication speeds. The current measured values can be easily identified through each phase. Operation states, event data, fault data and self diagnosis information can be accessed in real time. Interoperability between intelligent electronic devices is possible using USB ports. Energy efficiencies and reduced manpower contribute to the grid becoming less of a burden on resources.

Important Considerations When Buying Electronics

Tablets, laptops, mobile phones, and other electronic products – lots of people dream to buy these items in various types and brands. Are you one of them? Probably! Or if not, you might at last have one dream phone or one dream gadget. Have you bought any electronic item? What are your requirements when choosing a certain product to buy? Dear, electronics are somehow pricey (depending on your financial situation), so you should be very careful in choosing which product to buy. Some of these items have become a necessity these days; hence buying the right product has become very crucial as well. Want to learn about important concerns when buying electronics? Here are some tips for you:

• Check your budget.

Let’s say you need a mobile phone for business purposes. If that’s the case, then you should opt for one that won’t make you exceed your budget.

Are you buying that high-end tablet because you need it? Or are you buying it for the mere purpose of following the trends? In choosing any gadget, it is important to closely look at the features and specifications. Do you need all of them? Will you be able to use them? The answer to these questions should be a resounding yes. If not, it’s best not to buy the item.

• Don’t be easily persuaded.

Sure, you’ll find a lot of great offers: promos, incentives (like getting a free item when you purchase a particular model), etc. Take a close look at them before making a decision. Don’t be easily swayed by good sales talk and advertisement especially if your budget is limited. You should buy an item because you really like it and you made sure it is worth spending on; not because you were easily convinced by a random person or advertisement.

Buying electronics requires making wise decisions. There’s nothing wrong with following the trends, but it is important for you to always get your money’s worth in everything you buy. You should be able to make use of every feature of the item. You should be able to use it for a long time. Meanwhile, following the above-mentioned tips is your choice. It’s your money we’re talking about, anyway. Do you want to waste it? Probably not.

How to Plan Energy Efficient and Practical Kitchen Lighting

When it comes to designing your kitchen space, it is sure that there are several elements that you want to include in your creation, including practicality and energy efficiency. On top of this, it is important that your lighting solutions are also aesthetically pleasing, especially since you may be spending a considerable amount of time in this space.

It is first of all worth noting that perhaps the best lighting solutions for your kitchen are LED ones, as this is a technology that may require a little expenditure upfront, but will pay itself back a hundred times over throughout the many years that you and your family will use your home.

Whether you opt for LED GU10 bulbs or MR16 lamps, one thing is for sure: you can save a great deal of money on your energy bills if you invest in this lighting solution instead of more conventional lighting options.

It is also worth considering that this lighting option can also be a particularly aesthetically pleasing one; with dimmable LED and CFL on the market today, it is now easier than ever to enjoy high quality and flexible lighting solutions throughout all of your property, and only for a reasonable upfront investment for incredibly beautiful results.

Good kitchen lighting also needs to be practical, however, which is why you need to take into account a number of other factors when choosing your lighting options in your kitchen space. One thing you will need for sure is efficient task lighting, so whether you opt for LED GU10 bulbs or dimmable CFL, make sure that your choice can live up to the job you assign to it.

Several places that you are sure to need lighting in are the areas that you frequently use to prepare food or carry out other important kitchen tasks. These areas include worktops, sinks, stovetops, island counters, dishwashers, washing machines, areas used to operate coffee machines and blenders and other spots around your kitchen of a similar nature.

You can opt for spotlight LED GU10 bulbs or MR16 lamps here for bright and efficient light, or instead go for some other choices that are increasingly popular nowadays. One of these is sensor-operated lighting, which only switches on when you need it. Another choice is a track of tiny LED lights that provides great down lighting on the underside of cabinets to illuminate a worktop.

Whatever you choose, make sure that all these key work areas are sufficiently illuminated at the darkest times of day or night, in order to ensure the safety and security of you and anyone else in your household.

Many people also want to make sure that the lighting in their kitchen looks good, as well as provides the efficiency that they need in order to prepare food. The good news is that it is simple to add attractive lighting touches to your space; one popular solution is to use gorgeous pendant lamps over island counters and in the centre of a room.

It is also possible to add LED strip lighting in a variety of different colours to the underside of your cabinets and around the perimeter of the kitchen. This can make for a stunning contemporary look, especially when paired with the bright and modern overhead MR16 spotlights and LED GU10 bulbs.

Whatever you choose, remember that having the light fixtures put into place and wiring installed is the first thing that needs to be done when creating a new kitchen. It is therefore important to make your decision early on in your decoration project before all other elements – including plastering and installation of kitchen furniture – are put into place.

Where to Install Your Hidden Camera in the Home

Many people nowadays are opting to add extra security to their home in the form of hidden nanny cams and mini security cameras. These devices can be extremely useful in not only monitoring events in the property, but also making sure that valuables are more protected; this can be especially of use in a place with a great deal of expensive belongings or a lot of hired help.

One thing that people struggle with is where to hide their hidden security camera so that it picks up good footage of whatever they are filming but also remains discrete and undetectable. Here are some of our top tips on where to place these devices for best results and maximum protection.

A hidden security camera can be used in any room in the home, although care should be taken in place such as kitchens and bathrooms where there are a lot of water fittings and plumbing that could potentially cause damage to the equipment. Apart from taking care in these instances, however, there is a vast range of choice of locations to select from.

One of the top choices for placing this surveillance equipment in the home is on a bookshelf, as this is very easy to install and usually blends in perfectly with other items kept on the shelf. It is often possible to buy these kinds of devices in the shape of a book; otherwise, you may be able to buy a hollowed out book – or make your own – for concealing this surveillance equipment.

Another common place to put a hidden camera is on a TV stand, as this can blend in perfectly with the other equipment that is already here; people are very unlikely to notice a tiny camera that is placed next to a variety of other electronic equipment.

The advantage of these two choices is that they are in fixed positions that generally offer a great view of a room. Whereas a hidden security camera in a more obscure position may not pick up what is happening in the centre of a room, TV stands and bookshelves generally facilitate this, making for extremely useful footage.

Many people who invest in nanny cams to check up on their children and the hired domestic help that takes care of them have come up with some ingenious places to store these kinds of devices where they will go undetected. One of these is inside a teddy bear, which can be a great option in a nursery or child’s bedroom that is full of various toys.

The disadvantage to installing a hidden security camera in a stuffed toy, however, is that these items can be moved around, can fall over, and can generally be displaced, thus limiting the efficacy of this solution. If you do choose to hide a camera in a toy, make sure that it is in a good position in a room in order to capture useful footage, and that it also unlikely to be played with.

Finally, try putting your hidden surveillance equipment in smaller decorative items that would not look out of place in almost any room in the home. A commonly used example of this is in a mantle or wall clock, as these items are in no way suspicious, can be placed in any room and offer great footage of the space.

If you have mirrors or vases of flowers throughout the home, these also make great places to hide surveillance equipment. A two sided mirror may be a little expensive, but could definitely worth the investment for undetectable and highly effective surveillance in many rooms in your property.

When installing a hidden camera in your home, try some of the above ideas for subtle yet effective ways of monitoring the goings on in your premises. For best results, make sure that your equipment gets a good view of the room, is unlikely to be displaced, and is well concealed in order to avoid detection.
