What precaution should be taken when working with current transformer that is in service?
Its secondary must never be open circuited. If its burden is to be removed, then the secondary must be short circuited first, and removed only after the burden is replaced.
What is VA burden in electrical engineering?
The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.
Why is burden not used in protection ct?
Generally accuracy at low current values isn't important for protective functions. The burden is taken into account when looking at the saturation curve and available short circuit current to insure the CT doesn't saturate during fault conditions.
What is mean by burden of the current transformers?
The burden on a CT is the sum total impedance connected to the secondary - including the CT secondary winding coil resistance, lead resistance, and any loads attached (relays, meters, etc.).If this is for power calculations and CT saturation in three phase systems, remember you must multiply the lead resistance by two to get the total path resistance.Another AnswerWe use the word, 'burden', to describe the load supplied by the instrument transformer's secondary. This is normally a measuring instrument or protection relay. We use the word 'burden' to distinguish it from the 'load' supplied by the circuit to which the primary winding is connected.
Is it ok to have the dot on a current transformer upside down?
You are probably referring to a 'polarity mark'. This is very important if the CT's burden requires current to flow through it in a particular direction in order to work properly. For example, it won't make any difference if the burden's an ammeter. But if the burden is, say, a wattmeter, then it's very important to observe the CT's polarity mark when it is wired, otherwise the wattmeter might read 'downscale' (backwards). It's also very important when the CT supplies protection relays.

What are the benefit's of alliance in Hunger Games chapter fifteen?

Repay Your Debt Faster?
All students should focus on mastering the art of budgeting while in school. Students have hours and hours of time to spend while in school, as opposed to when they will be at work after graduation. When students work to better their budgets, one great area to focus on is repaying student loans. Every student should map out a thorough plan for paying off student loans after graduation, so they are not stuck with thousands of dollars in unbearable debt. Students should know exactly how much money they have borrowed from the government, in order to try to defray those costs while in school. When a student is studying in school, he or she can take all sorts of steps to lighten the burden of student loans. A student may be able to take on a part-time job and devote those savings specifically to the repayment of student loans after graduation. This is a great way to truly save thousands of dollars in the course of four or five years. A student may be able to save all sorts of funds while in college.
What is a benefit of using student loans to finance education?

How many days a week do Chinese students attend school?
In theory, school time from Monday to Friday. Owing to drastic competition many students have extra classes on Saturday. It seems the government has taken measure to lighten students burden, but it cant control the situtation.
What is double burden of disease and what is the situation in Asia?
Double burden of disease refers to the dual burden of non communicable and infectious diseases upon the low and middle-income countries. In fact, NCDs such cardiovascular diseases and diabetes are emerging and imposing now a new burden to those countries with limited resources and yet they are still struggling to meet the challenges of infectious diseases such as tuberculosis and HIV/AIDS. (Answer suggested by Thaddee Katembo, DrPH student, Adventist University of the Philippines-AUP)
