La-10 5-40A 0.2-0.5/10p 10/15va Indoor Semi-Enclosed Through-Wall High Voltage Current Transformer

10KV indoor high-voltage current transformer LA-10 semi-enclosed wall-type transformer, transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can turn high voltage into low voltage and large current into small current for measurement or protection systems. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, all refer to the rated value) in proportion, so as to realize the standardization and small size of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate high-voltage systems to ensure the safety of personnel and equipment.
In the power supply line, the current difference is from a few amperes to tens of thousands of amperes, and the voltage difference is from a few volts to several million volts. The current and voltage in the line are relatively high, such as direct measurement is very dangerous. In order to facilitate the measurement of the secondary instrument, it needs to be converted into a relatively uniform current and voltage, and the transformer is used to play the role of transformer transformation and electrical isolation.
