Domestic electrical engineer must be familiar with use formulation
Employing low-pressure YanDianBi opportunely
Lower stress YanDianBi is actually in other words auxiliary in addition to safe electronic devise domestic electrical engineer within frequent work with. Helpful to examine 500 v the examples below conductors as well as a good number of covering regarding electro-mechanical products is actually incurred. A standard low-voltage YanDianBi, transportable, so long as that master YanDianBi guideline, in addition to that acknowledged electro-mechanical guideline, accommodating talent considerably.
(1) judging switching present (ac) in addition to special present (dc) formulation
Pencil ac/dc, hvac dc bluish in addition to shiny
Hvac shiny neon colour photos, dc neon light source from one particular conclude.
Criteria:
Before advised viewers a little bit very first, utilize the lower voltage YanDianBi, have got to to the incurred body offers established examination determine; Before the unrecognized YanDianBi regular, shouldn't end up being used. Discriminant hvac, dc, it really is greatest that comparability among that "two", so it is rather totally obvious. Stops whenever calculating hvac neon spark simultaneously, whenever calculating dc neon quite stand out only in the end.
(2) decide a direct present is actually unfavorable formulation:
Pencil common sense is actually unfavorable, declaration regarding neon to discuss,
Entry shiny is actually unfavorable, that back-end in addition to shiny because the anode.
Criteria:
That front-end comes from YanDianBi that idea conclude in the neon area rug, neon back-end comes from one particular conclude in the side, entry conclude in addition to shiny because the cathode, whereas for any good. Experiment must focus on: that provide voltage regarding 110 v in addition to over; When those that have the garden area efficiency, any side to touching any power provide, another any hand-held calculating pen, pencil assessed power shiny mind struck any post, neon front-end is quite light source, touching the power assessed is actually unfavorable; When neon backend is quite light source, touching the power assessed is actually good, this can be reported by that dc regarding unidirectional stream and also the electrons in the cathode into the anode stream guideline.
(3) common sense own dc power without grounding, is actually unfavorable terrain variation formulation
Substation dc coefficient, electroprobe struck not stand out;
When light source close to the pen idea, that anode grounding negligence;
When light source close to the finger conclude, terrain negligence in the cathode.
Criteria:
That dc coefficient regarding power place in addition to substation, is made for terrain efficiency, place to the terrain, work with YanDianBi to touching that good as well as unfavorable, shiny neon is actually shouldn't, and when, then dc system earthing method; When light source around one particular conclude in the pen, will be the anode grounding; When light source around one particular conclude in the fingers, it really is unfavorable terrain.
(4) common sense by using action non-synchronous formulation
Not one but two cable will be the same, every side possessing any pen,
Not one but two toes in addition to terrain efficiency, one particular touching every pen to collection,
Watching any pen with all the eyesight, usually do not light source within action differs.
Criteria:
Once the experiment, remember together toes in addition to needs to be insulated. Due to the fact many of some of our state tend to be 380/220 v power provide, in addition to basic straight grounding transformer is actually greatly used, so complete the test, among one's body and also the planet needs to be insulated, stay away from any circuit, in order to stay away from incorrectly recognized common sense; Experiment, not one but two shiny in addition to shiny present several, so only have a look at any may.
(5) decide that 380/220 v several action several cable system power provide circuitry action earthing negligence collection formulation
Y interconnection regarding three-phase outlines, electroprobe struck not one but two shiny,
Outstanding any perfection is actually fragile, that action conductors own grounding;
When it really is practically invisible light source, shiny earthing negligence.
Criteria:
Power transformer secondary side is normally get in touch into a Y design, in the basic point grounding system regarding three-phase three-wire system, employing YanDianBi struck several action collection, not one but two actual, a little better compared to regular, nonetheless to the additional a reduced amount of perfection, perfection, explained this specific fragile action cable grounding method, but additionally not very severe; If the actual is quite shiny, in addition to outstanding any practically invisible light source, is niagra consistent with shiny terrain negligence.
