FAQ
Q: How long can the equipment operate continuously at rated current?
A: HPCI-1000A can operate continuously for 30 minutes at 1000A rated current with the built-in forced air cooling system. For currents ≤500A, it can operate continuously for an unlimited time. For longer duration tests at rated current, we recommend using our water-cooled series high current generators.
Q: Can it be used to test three-phase equipment?
A: Yes. For three-phase equipment testing, you can use three single-phase HPCI-1000A generators simultaneously, or choose our three-phase series high current generators (HPCI-1000A-3P) which can output balanced three-phase currents.
Q: What safety measures are in place to protect operators during high current testing?
A: HPCI-1000A is equipped with a comprehensive safety protection system:
- Isolated control circuit: Low voltage control circuit is completely isolated from high current circuit
- Multiple electrical protections: Overcurrent, overload, overheat and short circuit protection
- Mechanical protections: Zero position protection and emergency stop button
- Warning system: Audible and visual alarms for abnormal conditions
- Clear safety signs: Prominent safety signs on the equipment to remind operators of potential hazards
Q: How to calibrate the current measurement accuracy?
A: The instrument can be calibrated using a standard high current transformer and standard ammeter. Users can connect the standard equipment in series with the output terminal, apply different current levels, compare the measured values with the standard values, and adjust the calibration coefficient in the instrument menu. The calibration procedure is simple and fast, and the instrument provides a built-in calibration wizard to guide users through the process.
