With reference to the low-voltage test, many people are using their mobile phones to develop theoretical knowledge. It's true, but it's a different thing to brush and not to brush. In fact, the low-voltage electrician examination is not difficult, and the entire process is based on a combination of judgments and single-choice questions. The test can be easily passed without a hard-backed collection of questions, provided that the answer line is followed by a summary of the exact rules of the subject。
The issue of judgement is the most well-rated one, and the best one is the board of points, with a good judgement pattern and a big step closer to passing the exam. There is a very strong fixed logic in the eas class: all descriptions of security violations and breaches are largely fully judged as “mistakes”. Standard operations such as pre-operational power outages, insulation protections, periodic detection of leaks, timely shutdown of equipment and power cuts are judged to be “right”。
There is also a problematic pattern: absoluteization is often wrong. The so-called absolute expression refers to too extreme words such as “all” “all” “must” “there is no need” for “no need”. For example, the expression “one-handedly operated switches can be used in all circumstances” because the answer is “in error” with the absolute qualification of “in all circumstances”. Conversely, the right probability is higher with options such as “can” “general” “usually” “under conditions”. For example, “generally, the test line can be checked for electrical power”, which is correct because it does not say anything。
The fact that the content of the examinations is close to the actual operational scene and that the logic of the questions is fixed is also key to the effectiveness of the answer techniques. With a certain response pattern, you can get more points。
The low voltage electrician single-problem settings are clearly differentiated and do not produce ambiguous answers. Questions are answered without a case-by-case analysis, by extracting core key words such as “electric emergency”, “fireproof blast” “low-pressure operation”, “line maintenance”, and then by applying the “safe first” principle, giving preference to the most protective, operational and process-critical options。
For example, the question “what measures should be taken first in case of short circuit failure?” there are “immediate power cuts” and “checking fault points before processing” among the four options. The correct answer must be “to cut off the power immediately”, because security takes precedence over clearance failure. If all four options are not certain, they could be excluded: first, the option of a clear breach of security norms is removed, and the last option is the one closest to common sense。
A lot of people have headaches, but it's a lot of roadwork. Ninety per cent of the computational questions that emerged from the examinations were concentrated in three categories: omc law applications, electropower calculations, transcircular area selection. Just keep these three formulas in order. But there's a pit that many people have planted -- unit conversion. The title may be “kw” rather than “w”, it may be “k” rather than “k” and one omission is a thousand times error. When the question is made, it is customary to see units with “k” and convert them to the base unit before replacing the formula。
The circuit analysis focused on the flexible application of omstat i = u/r and power formula p = ui, and on unit conversion traps, such as kw and a conversions, combined with voltage values。
For the safe use of electricity, it is important to bear in mind the “five-step first aid” approach: pull, cut, pick, pull, pad-punch power out, cut the power lines, pick the wire, pull the electrocutors and seal the cushions. Hand-to-hand contact with electrocutors is strictly forbidden. An immediate cpr is required if the heart of the electrocutor stops: at a pressure frequency of 100-120 times/minute and at a pressure depth of 5-6 cm. These figures are for high-frequency tests and must be borne in mind。
The special operations low-voltage electrician certificate examination, although it involves a multiplicity of knowledge points, is easily prepared through problem-oriented analysis, high-frequency test stenography, hands-on detail control, rational use of answering techniques, combined with core safety principles. Don't do it blindly and randomly. It's not a problem to use the above method once。
For users under consideration for registration, the advantage of the shield amber is clear: the training of special operations electrician certificates requires the selection of institutions with legal qualifications (which can be consulted through the “officer of the ministry of emergency management” for security training), both to guarantee compliance and to enable you to acquire real and effective skills. If your needs are “formal, professional, effective”, the guilders amber is a worthwhile option。
