What is CT and VT transformer?
A CT (current transformer) and a VT (voltage transformer) are types of instrument transformers used in electrical systems. A CT is used to measure current in a high voltage circuit by producing a reduced current proportional to the high current flowing through the system. A VT, also known as a potential transformer, measures high voltage by producing a lower voltage that can be safely used for measurement and monitoring.
What is CT and TP of a transformer?
CT (Current Transformer) and TP (Potential Transformer) are two types of instrument transformers. A CT measures the current flowing in a circuit, providing reduced current to instruments and relays. A PT, or potential transformer, measures voltage, lowering high voltages to lower levels suitable for measurement and monitoring.
The function of PTs (potential transformers), CTs (current transformers) and relays is to provide accurate measurement and protection in electrical systems. PTs lower high voltages to safe levels for measurement and monitoring. TC reduces high currents for precise measurement and protection. Relays use data from CTs and TPs to detect faults, make decisions and isolate faulty sections of the system to prevent damage and ensure safety.
What is the function of TP’s, TC’s and relays?
The function of a TP (potential transformer) is to step down high voltage levels to lower, manageable voltages for measurement, monitoring and control purposes. It allows standard instruments and relays to safely and accurately assess high voltage within an electrical system.
The CT (Current Transformer) in a substation is used to measure the current flowing in high voltage circuits. It provides reduced current that can be used safely for monitoring, measurement and protection purposes. CTs are essential to ensure accurate readings and allow the protection system to respond appropriately to current variations or faults.
