Multi-function SAVS Recorder for Power System Monitoring - China Suppliers and Factory
Products Description
The SAVS is a multi-function recorder that includes the features of many separate instruments for monitoring a power system. These include system stability, and power quality. SAVS can be used both on HV and LV bus. The voltages and currents on three phase lines are recorded via standard instrumentation transformers to 16-bit accuracy. The state of protection relays and switchgear can also be monitored via auxiliary switch contacts.

Frequently Asked Questions
What are the primary functions of the SAVS recorder?
The SAVS is a multi-function recorder designed to monitor power systems. It integrates the features of various separate instruments to monitor system stability and power quality on both High Voltage (HV) and Low Voltage (LV) buses.
How accurate is the measurement and data logging on the SAVS?
Voltages and currents on three-phase lines are recorded via standard instrumentation transformers to a high-precision 16-bit accuracy, ensuring reliable analysis data.
Can the SAVS track external equipment states like protection relays?
Yes, the state of protection relays and switchgear can be actively monitored using auxiliary switch contacts connected to the SAVS recorder.
What technical upgrades does the SAVS feature compared to traditional monitors?
The SAVS features six major technical upgrades, including an increased sampling frequency of 20kHz, extended panoramic recording duration (-1s to +30s), longer power-loss backup (60s), Beidou/GPS time synchronization, real-time voltage drop analysis, and intelligent solution recommendations.
How does the SAVS identify and analyze voltage sags?
The system monitors sag duration, depth, drop rate, and phase changes (1-phase, 2-phase, or 3-phase). It also intelligently judges the source of the sag, identifying whether it originates from the power grid or a local load short circuit.
How can I export the recorded data from the device?
Recorded data can be easily exported directly to a USB flash drive or communicated to your system's backend database via multiple protocols and interfaces.
