Indoor Instrument transformers such as current and voltage transformers are commonly used in electrical power systems to measure and transform electrical quantities such as current, voltage, and power. They are typically used in indoor electrical distribution systems, such as those found in commercial buildings, industrial plants, and other low voltage applications.
These transformers are designed to operate at low voltage levels and are used in conjunction with measuring instruments, protection relays, and other electrical equipment to ensure accurate and safe operation of the electrical power system. Indoor current transformers (CTs) are used to measure electrical current, while voltage transformers (VTs) are used to measure electrical voltage. Combined CTs and VTs are also available, which provide both current and voltage measurement in one device. The use of indoor current and voltage transformers enables accurate measurement and control of electrical power systems, ensuring the safety and reliability of these systems.
In general, Instrument Transformers play a critical role in ensuring the accurate and safe operation of electrical power systems by providing reliable and accurate measurements of electrical quantities.
Below are two common application examples of Indoor Current & Voltage transformers:
- Power Quality Monitoring: Indoor current and voltage transformers are commonly used in power quality monitoring systems to measure and record the electrical quantities in a power system. This information is used to identify and analyze power quality issues, such as voltage sags, surges, and harmonics, in order to improve the reliability and efficiency of the electrical power system.
- Substation Monitoring: Indoor current and voltage transformers are used in electrical substations to monitor and control the electrical power system. They are used to measure the electrical quantities in the substation and provide this information to protection relays, which are used to detect and isolate faults in the power system. The use of indoor current and voltage transformers in substations helps to ensure the safe and reliable operation of the electrical power system.
