Electrical Isolation from High Rated Winding:
Instrument transformers provide electrical isolation from high rated winding. This means that the primary winding (high voltage side) is physically separated from the secondary winding (low voltage side) in the instrument transformer. This isolation helps prevent any potential electrical hazards and ensures the safety of the equipment and personnel.
Importance of Electrical Isolation:
- Protects equipment: By isolating the high voltage side from the low voltage side, instrument transformers help prevent damage to sensitive equipment that may not be designed to handle high voltages.
- Prevents electrical shock: Electrical isolation reduces the risk of electric shock to personnel working with the equipment, as it creates a physical barrier between high and low voltage components.
- Ensures accuracy: Isolating the windings helps maintain the accuracy of the measurements taken by the instrument transformer, as there is no interference from the high voltage side.
- Compliance with regulations: Electrical isolation is often a requirement in electrical systems to comply with safety standards and regulations.
Types of Instrument Transformers:
- Current transformers (CTs): Used to measure alternating current (AC) on high voltage circuits. They provide a scaled-down current in the secondary winding for measurement and protection purposes.
- Voltage transformers (VTs) or potential transformers (PTs): Used to step down high voltage for measurement and protection. They provide a scaled-down voltage in the secondary winding.
Conclusion:
Instrument transformers play a crucial role in electrical systems by providing electrical isolation from high rated windings. This isolation ensures safety, accuracy, and compliance with regulations in various applications, making instrument transformers essential components in power systems.
