Frequently Asked Questions (FAQ)

Q1 What is the SAVS recorder and where can it be applied?

SAVS is a multi-function power recorder that combines features of multiple separate instruments for power system stability and power quality monitoring. It is versatile and can be deployed on both High Voltage (HV) and Low Voltage (LV) buses.

Q2 How accurately does SAVS record voltage and current data?

Voltages and currents on three-phase lines are recorded via standard instrumentation transformers with 16-bit accuracy, enabling precise identification of sags as short as 1ms with sampling frequencies up to 20kHz.

Q3 What are the panoramic recording capabilities during a voltage sag event?

SAVS features panoramic recording covering 1 second before the sag and up to 30 seconds after the sag (-1s to +30s), as well as 60 seconds of duration recording in the event of power loss.

Q4 Can SAVS identify the cause and source of a voltage sag?

Yes, SAVS features intelligent judgment capabilities to discriminate whether a sag originates from the upstream power grid or a downstream load short circuit, while also identifying phase conditions (1-phase, 2-phase, or 3-phase).

Q5 Does SAVS eliminate the need for additional Power Quality (PQ) monitors?

Yes. SAVS includes full routine PQ monitoring covering voltage, current, power factor, total harmonic distortion (THD), and unbalance, eliminating the necessity for standalone PQ monitors.

Q6 How are data exported and synchronized in the SAVS system?

Data can be easily exported via USB flash drive or communicated to backend systems through multiple protocols and interfaces. It supports precise time synchronization via GPS or Beidou.
