Summary It is important to have system relays that protect transmission lines against short circuits and ground faults by dividing into two all faults on the line it protects regardless of type or system conditions. One of the classes comprises of faults that occur between the relaying station and the next sectionalizing point on that line Patrice Bergeron Canada Jersey , and the other class is made up of all other faults. Distance relays have been used for protection of single lines, while balanced-current relays have been used for parallel lines. Distance relays should be made sufficiently accurate and rapid so that the balanced- current relays get dispensed with or provided for backup protection only. The article aims at providing a comprehensive and systematic analysis of the voltages and currents used to operate distance relays. Distance relays comprise of two basic types namely impedance relays and reactance relays. The impedance relay that is indicated as impedance makes a comparison of the magnitudes of the voltage and the current. The reactance relay that is shown as reactance compares the magnitude of that component of the voltage 90 degrees out of phase with the current and the magnitude of the current. The indicated impedance is equal to the actual impedance of the circuit from the relay to the fault under line-to-line fault conditions on an individual single-phase line.

Do I need Building Regulation approval for a conservatory
To help you understand these issues I detail below some of the "conditions" attached to planning permission and building regulations. (These apply to EnglandWales only) Scottish, Irish and North American regulations are quite different ? You should in all instances take local advice.
PLANNING PERMISSION
In England and Wales you will not usually require planning permission Jamie Benn Canada Jersey , provided you do not exceed the permitted development limit for your property (which is 50-70m cubed, depending on where you live). Notable exceptions to the above are listed buildings and conservation areas. Please note that if your property has been extended in the past - you will have used up some or perhaps all of your "permitted development" area and may need permission. Its also worth noting that occasionally "permitted development" rights may be withdrawn from a property and any extension however small needs planning. If in doubt check.
BUILDING REGULATIONS
Generally speaking conservatoriessunrooms on residential property are exempted under Building Regulations. Below are some of the Exemption Criteria - under the Building Regulations 1991 (as amended). These criteria must be met for a conservatory extension to be classified as exempt:
a) The extension has a completely transparent or translucent roof. b) The extension walls are substantially glazed. (Should not have more than 25 % of its wall area as brick work) c) The extension has a floor area not exceeding 30m squared. d) The extension is sited at ground level. e) The extension is permanently separated from the remainder of the property by means of a door. f) The extension is not permanently heated! g) The glazing satisfies the requirements of part N, Schedule 1 (toughenedsafety glass) h) The extension does not contain any drainage facilities. (i.e. sink Shea Weber Canada Jersey , WC, or washing machine)
An example of where building regulation approval may be required is a Kitchen Conservatory Extension. I suggest you contact your local council - explain your intentions - they will be able to give you more specific advice.
One word of "warning" - a fair number of people will have constructed conservatories with drainage inside, more than 25 % brick wall area and permanent heating. In a lot of instances they will not have got the approvals required - either because they where unaware or badly advised. I believe building control officers are taking these situations more seriously - leading to structures be taken down in the most severe instances.

Hypnosis is a term that brings up a variety of images: of people sleepwalking P. K. Subban Canada Jersey , stage shows with people doing odd things or a man with a thick German accent, saying, "You are getting very sleepy ..." Thanks to talk shows Alex Pietrangelo Canada Jersey , it also brings up fears about repressed memories and painful accusations.
Although all of the above can and does happen, hypnosis, well and ethically used Duncan Keith Canada Jersey , is in reality simply a way to help people achieve the changes they desire.
It is really a very commonplace phenomenon. We all go into a state of something like hypnosis at least twice a day: when we are waking up and when we are going to sleep.
Our bodies are relaxed and out minds are able to focus. How many of you get some of your best ideas as you are waking or falling asleep?
In addition, if you have ever driven on the interstate for a lengthy period of time, you have been hypnotized.
