Frequently Asked Questions
1. What is the primary function of the SAVS recorder?
The SAVS is a multi-function recorder designed to monitor power systems. It integrates the features of multiple individual instruments to track system stability and power quality on both High Voltage (HV) and Low Voltage (LV) buses.
2. How does the SAVS monitor and record voltage sags?
The SAVS provides real-time monitoring and recording of voltage sags. It captures the sag start time (with 1s pre-sag recording), end time (with 30s post-sag recording), duration (identifying down to 1ms sags), drop depth (residual voltage), drop rate, and surge current changes.
3. Can the SAVS identify the source and phase of a voltage sag?
Yes. The SAVS features intelligent judgment capabilities to determine if the sag originates from the power grid or a load short circuit. It also discriminates whether the sag affects 1-phase, 2-phases, or 3-phases through phase separation monitoring.
4. What technical upgrades does the new SAVS feature?
The SAVS has undergone six major technical upgrades: a higher sampling frequency (up to 20kHz), extended panoramic recording duration (-1s to +30s), extended power loss recording (up to 60s), GPS/Beidou time synchronization, enhanced real-time analysis capabilities, and automatic solution recommendations.
5. What physical and design improvements have been made to the device?
The device features four process upgrades: an upgraded 10-inch touch screen interface, improved wiring terminals and methods, a high-strength anti-vibration structural design, and an artwork-style aesthetic layout.
6. How is the recorded data exported from the SAVS?
Data can be easily exported directly to a USB flash drive or communicated to the backend system. The device supports multiple communication protocols and interfaces for seamless integration.
