Instrument transformer, also known as measuring transformer, is a special type of transformer mainly used to transmit information to measuring instruments, meters, protection and control devices. Instrument transformers are divided into two categories: voltage/potential transformers and current transformers. Their main function is to convert high voltage or high current into low voltage or low current, in order to standardize and miniaturize measurement and protection equipment. Our company can produce voltage transformers, current transformers, zero sequence current transformers, and combined transformers. The main functions of instrument transformers include: Electrical isolation: Convert a high voltage or high current into a secondary low voltage and low current, transmit signals through electromagnetic induction, ensure the isolation of secondary equipment from high voltage, and guarantee the safety of equipment and personnel. Expand application range: By using different transformation ratios, smaller instruments can be used to measure higher voltages or currents, expanding the application range of instruments. Standardization: Standardizing the specifications of secondary instruments and relays is beneficial for the standardization and unified management of equipment. Voltage Transformer: Convert high voltage into standard low voltage (such as 100V) for measuring high voltage. Current Transformer: Convert high current into standard low current (such as 5A) for measuring high current.
