11kV Potential Transformer Manufacturer in India
Amrest Electricals Limited manufactures and supplies 11kV Potential Transformers (PT), also known as Voltage Transformers (VT), for medium-voltage distribution, metering, protection and control applications.
11kV Potential Transformer
An 11kV Potential Transformer is an instrument transformer used in medium-voltage power systems to safely measure high voltage. It electrically isolates measuring and protection equipment from the high-voltage network while providing a proportional secondary voltage. AMREST 11kV PTs are supplied according to the required voltage ratio, accuracy class, burden, application and installation.
11kV PT for Metering
Reduces the primary voltage to a suitable secondary voltage so that metering equipment can safely monitor the electrical system.
- Energy meters
- Voltmeters
- Power meters
- Power factor meters
- Monitoring systems
11kV PT for Protection
Provides a proportional voltage signal to protection relays, helping the system identify abnormal voltage conditions and initiate the required protective action.
- Under / over voltage protection
- Directional and distance relays
- Earth fault detection schemes
- Control and monitoring panels
