Product functions
1. Real-Time Signal Monitoring The UHV-602 continuously monitors electrical signals during equipment operation and displays measurement results in real time. Engineers can observe changes in voltage, current, frequency, power, phase-related parameters, and switching states while testing is in progress.
2. Transient Event Recording The recorder captures electrical waveforms associated with transient events such as equipment switching, generator start-up, system disturbances, and abnormal operating conditions. Recorded waveforms can be reviewed after the event to determine how electrical parameters changed over time.
3. Fault Waveform Analysis The UHV-602 provides waveform data for investigating electrical faults and abnormal system behavior. Engineers can compare signal changes during different stages of an event and use the recorded data to assist with fault identification and troubleshooting.
4. Electrical Parameter Calculation The system processes acquired signals to obtain important electrical quantities, including frequency, active power, reactive power, power factor, sequence components, phase angle, power angle, and impedance. These calculated values provide additional information for evaluating equipment and system operating conditions.
5. Generator Test Analysis The UHV-602 can be used to acquire and analyze electrical data during generator characteristic tests. It supports measurements associated with no-load, short-circuit, excitation, load, start-up, de-excitation, and step-response testing, helping engineers evaluate generator behavior under different operating conditions.
