what level of maintenacne is found at the forward support company
Any two legs of a three phase system can be classed as a single phase supply.Alternative AnswerAs the above answer points out, connecting a load between any two line conductors of a three-phase supply will give you a single-phase load. But you must, of course, take into account the voltage rating of the load you wish to connect.In Europe, three-phase low-voltage distribution is normally by means of a four-wire system, comprising three line conductors and a neutral conductor, operating at 400 V (line-to-line) and 230 V (line-to-neutral).Your single-phase load's voltage rating must, of course, match either the single-phase supply's line-to-line or line-to-neutral voltages. In Europe, most single-phase loads are rated at 230 V so, for a residential three-phase, four-wire system, it is usual to obtain a single-phase supply by connecting the load between any one of the line conductors and the neutral conductor.But, if you have a non-standard, 400-V single-phase load, then connecting that load between any two line conductors will also give you a single-phase supply.
stop cheating in your phase 1 test haha well caught deedee here! Well phase test is open book meaning you can research answers. 2 hazards, faulty wiring and loose drill bit
The practical exercise does not have an exact answer. The idea is that the student will do something in real life to put the theories he or she has learned into practice. To that end, all answers will be different.
There is no single 3-phase voltage that answers this question. Just as you have three different phase to neutral readings, you will have three different phase to phase readings.Voltages used to described a power distribution system are 'nominal' values. For instance, the battery in my auto is a '12 volt' battery, yet fully charged it measures more like 13.6 volts, and that number changes with load and state of charge. We still call it a 12V battery. The nominal system voltage in your question would be the 230/400V 50Hz system used in Europe. We would measure about 230V phase to neutral, and about400V phase to phase. The individual phases could vary according to load conditions and transformer taps, but we would still use the nominal numbers when describing this system.Since your question is in the singular, the answer would have to be the nominal system voltage of 400. The formula is:single phase voltage * 1.73 = phase to phase voltage (nominal)If you really meant the exact voltage on each possible phase pair, then easiest will be to measure it. If you really want to mathematically calculate the phase to phase voltages given three unbalanced phase to neutral values, that is a pretty advanced subject I will leave to the next answerer!
Yes, there is a difference between single phase and three phase circuits.
Developing an emergency operations plan is an activity in this phase of emergency management
LOL...Really?
The warfighter's concept of operations to ensure we know how the software will be used.
Phase 4
4
sustainment
Sustainment
Phase IV, Stabilize: Phase IV begins when civil authorities or follow-on DOD forces scale down operations and civil authorities resume "new normal" activities.This phase ends when redeployment criteria have been met.
Good communication is found on the support phase of the PR.
This phase is known as reset.
The best thing to do is to tell them it is not a phase and that they should support you. If they insist it is, which they will, tell them that even if it is a phase, I want you to support me and my decisions, now, here. Tell them not to wait until they are persuaded that your Bi to support you, they should support you now.
Single phase loads can go as high as the connected device requires. Of course the higher you go with the load , so goes the equipment to support it. Larger wires sizes, breakers etc..
