[Features]
This product is an AVR for On-Load Tap-Chaging (OLTC) starting of a single operation transformer. It can calculate the correction values of AVC in accordance with the cable load characteristics and manage the optimal voltage. It facilitates high precision, convenient installation, communication functions, and user oriented convenience. In addition, for bus bar voltage management, an additional Digital Voltmeter (DVM) function is included. It is a digital automatic voltage controller that can efficiently manage the voltage affected by a decrease in the bus bar and cable voltages.
• Processing Speed, accuracy improvement
- Adopt 32bit digital signal processor
- Possible to measure 0.1V and 0.01A by 16Bit A/D converter
• DVM function
- Possible to regulate voltage though the voltage of bus and feeder decrease rapidy
• Monitoring function
- Display LED and output alarm signal in case error occurs
• Event data record
- Event data( up to 100e) record
• Tap operation of OLTC counting function
- Count and record the number of tap operation
