Reliabel Instrument Transformer Supplier and Factory
Contact Ceho to purchase our Instrument Transformer, as well as other products that can configure a complete set of electrical equipment for you. This specialized device reduces high voltage and high current to standardized low levels, providing the necessary isolation between high-power primary circuits and low-voltage secondary circuits, and is also a precise and efficient device.
Main Type
Current transformer and voltage transformer, these two are the main types, but there is a more special category, also Ceho can be systematic, that is, combined instrument transformer.
Current transformer is used to reduce high primary current to standard secondary current. Its primary winding is connected in series with the conductor of current to be measured. The output of secondary winding is connected to ammeter, power meter, electric energy meter and protective relay.
Voltage transformers are used to reduce high system voltages to standard secondary voltages, with primary windings connected in parallel between phase and neutral conductors, or between two phases.Secondary outputs are used for voltmeters, wattmeters, frequency meters, synchronizing devices and protective relays.
The combination is also very easy to understand, that is, integrating the two of them together.
What Factors Should Be Considered When Selecting Load Ratings for Instrument Transformers?
The choice of load pairs is important to maintain nominal accuracy.The total connection load includes the impedance of all connecting wires, terminals and connected equipment, so when selecting, confirm that the rated load of instrument transformer is equal to or greater than the calculated total connection load.If you are unable to confirm this by yourself, please contact Ceho with the relevant information and we will work out the perfect one for you.

Outdoor Three-Phase Oil-Immersed Combined Instrument Transformer
Ceho is a reliable supplier of Outdoor Three-Phase Oil-Immersed Combined Instrument Transformer. Combined Interchange Inductors (CITs) integrate current transformers (CTs) and voltage transformers (VTs) into a compact unit. The "three-phase" design can handle all three-phase voltages simultaneously, while "oil-immersed" indicates that the core and windings are submerged in insulating oil within a sealed tank. This product is meticulously designed to withstand harsh environmental conditions, making it a durable choice for outdoor substation applications.
Three-Phase Epoxy Resin Cast Combined Instrument Transformer
You can rest assured to buy Three-Phase Epoxy Resin Cast Combined Instrument Transformer from Ceho. A combined transformer is a power device primarily used to convert high voltage or large current into standard low voltage or standard small current, aiming to standardize and miniaturize measuring instruments, protection devices, and automatic control equipment. It consists of current transformers and voltage transformers, which can reduce high voltage and large current to a suitable measurement level according to the needs of the power system. The design and application of combined transformers aim to improve the safety and reliability of power systems while optimizing the performance and efficiency of power equipment.
Outdoor Three-Phase Dry-Type Combined Instrument Transformer
The global pursuit of smarter, safer, and more resilient power grids is reshaping the entire industry. For utilities and industrial operators in the US, Southeast Asia, and Germany, selecting the right metering and protection equipment is crucial. Outdoor three-phase dry-type combined instrument transformers stand out as an excellent choice, integrating metering and protection functions into a rugged, maintenance-free device.
