Application transformer should note the following aspects: 1, current transformer primary current rating generally based on the line of 1.2 to 1.4 times the current selection of the current transformer, which is considered the main current transformers and ammeter will not burn when the line is overloaded or Meter and other electrical equipment. 2, the current transformer rated current can not choose the actual operating current transformers that much difference than the line, which will affect the measurement accuracy of the current transformer. 3, the transformer is within the rated load range of secondary output transformer in order to ensure accuracy. Therefore includes a secondary line load and load measuring devices are the actual work load transformer, when the transformer secondary load is greater than the actual output transformer secondary transformer rated output load Panzhihua Which is good, transformers accuracy will be reduced, severely burned when the transformer is overloaded. 4, when the load is lower than the actual output transformer secondary transformer rated secondary output load, the accuracy of the transformer will be reduced. 5. As noted in the choice of the appropriate use of different occasions transformer products. 6. Do not mix in the outdoor transformers transformers and households. Transformer type difference: The most important difference is the status of their work in normal operation, mainly in the following aspects: 1 voltage transformer flux density close to saturation during normal operation, and fault when the magnetic flux density is decreased; When the current transformer work flux density is low, and when a short circuit due to a short-circuit current becomes large, the magnetic flux density is greatly increased, and sometimes far more than the saturation value. 2, the voltage transformers are used to measure high voltage power transformers special transformers Suining Which is good, it will convert the high voltage required for the proportion of lower voltage, then connect to the meter to measure up. Voltage transformer primary voltage matter how many volts, while the secondary voltage are generally defined as 100 volts, the voltage to supply the voltage meter, power meter and kilowatt-hour meter and relay coil voltage required. 3, can short-circuit current transformer secondary, but not open; voltage transformer secondary can open, but not short-circuit. The large proportion of current required to convert small current electrical equipment, called the current transformer. Current general provisions of current transformer secondary side is 5 A or a security to supply meter, power meter, kilowatt-hour meter and current relay coil current. 4, for the load on the secondary side, the voltage transformer of a small internal impedance even negligible, can be considered a large voltage transformer is a voltage source; and a current transformer has great resistance, as well as can considered to be a current source of infinite resistance. Which is good Panzhihua transformers, transformers, power is supplied by the Xi'an Huayi Huayi power plant.
