Multi-Function SAVS Recorder for Power Monitoring - China Suppliers & Factory for HV/LV Systems
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 is the SAVS and what are its primary applications?
The SAVS is a multi-function recorder designed to monitor power system stability and power quality. It is suitable for use on both High Voltage (HV) and Low Voltage (LV) buses.
What parameters does the SAVS track during a voltage sag event?
The SAVS monitors and records sag start/end times, sag duration, drop depth, drop rate, current changes, sag source identification, and sag phase classification (1-phase, 2-phase, or 3-phase).
How does the SAVS identify the source of a voltage sag?
The system uses intelligent algorithms to determine whether the voltage sag originates from the power grid or is caused by a load short circuit.
What are the key technical upgrades of the new SAVS model?
Key upgrades include a higher sampling frequency of 20kHz, an extended panoramic recording time (-1 to +30s), a 60s power loss ride-through, and GPS/Beidou time synchronization.
How can data be exported from the SAVS device?
Data can be exported directly to a USB flash drive or transmitted to a backend system using multiple communication protocols and interfaces.
Does the SAVS support routine power quality monitoring?
Yes, it supports routine monitoring of voltage (V), current (I), power factor, Total Harmonic Distortion (THD), and unbalance, eliminating the need for additional power quality monitors.
