Power workers in the work, often need to test the performance of power transformers and relays, need to use relay protection tester, in the choice of time, relay protection tester and divided into single-phase, three-phase, six-phase points, sometimes let the power work car is very troubled, in the end which kind should be used? What is the difference between these three types of follow-on insurance? This article gives you a brief introduction.
Single-phase, three-phase, six successive electric protection tester, mainly focused on the "phase" above, single-phase refers to the output of single-phase current voltage, three-phase refers to the output of three-phase current and voltage, six refers to the output of six-phase current and voltage.
Single-phase relay protection tester is belong to the basic model of relay protection tester, it is mainly used for some voltage grade and the high accuracy of test equipment, is an older equipment, application scope is limited, but because of low cost, low prices, there are still certain application scenario, the electricity workers need careful consideration.
Three-phase relay protection tester is now more mainstream relay protection tester, can output three-phase current and voltage, can cover the current more mainstream power transformer and relay test, has a larger range of application, at the same time the price is not very high, is now more mainstream relay protection tester.
Six successive electric protection tester is following, can output the six phase current and voltage, can be competent in almost all the transformer and the relay testing work, has the very high application value, and accuracy is also better in this three kinds of the insurance, but because of the high cost, so the price is very expensive, generally used for precision and the unit of voltage grade is higher.
Single one after another, in general, buy, three successive, six have been confirmed, the three following each has his strong point, wide application of high precision is high, the price of the application, low price is low precision, is bearing direct proportion to the price and cost performance, electricity workers in the process of real options, and need to choose according to their own actual situation, depending on what they usually are test, Accuracy requirements, so as to choose to choose the appropriate relay protection tester.
