FAQ

Q: How do I determine the correct kVAr rating for my facility?

Calculate 75% of maximum reactive power demand from your utility bills. Alternatively, conduct a power quality audit using Class A power analyzers per IEC 61000-4-30.

Factor in future load growth. Ensure the unit can handle 110% of calculated demand.

Q: Why does the unit sometimes disconnect capacitors automatically?

The controller protects against overvoltage conditions, harmonic resonance, or overcurrent situations. This is normal operation per IEC 60831 standards.

It prevents capacitor damage and ensures system safety. Check for voltage variations exceeding ±10% or harmonic distortion above 5%.

Q: What maintenance is required for optimal performance?

Perform monthly visual inspections. Conduct quarterly capacitor bank testing using insulation testers per IEEE 18.

Annual contact inspection and cleaning are necessary. Biannual controller calibration verification ensures accuracy.

Replace capacitors showing more than 5% capacitance drift or elevated temperature readings.

Q: Can the unit operate with variable frequency drives?

Yes, but harmonic filtering may be required. Units with detuned reactors (5.67% or 7%) prevent resonance with VFD-generated harmonics.

Conduct harmonic analysis per IEEE 519 to verify compatibility. Ensure total harmonic distortion remains below 5%.

Q: How do I troubleshoot communication failures with building management systems?

Verify Modbus RTU parameters match controller settings. Check cable shielding and grounding per IEC 61158 standards.

Ensure proper termination resistors are installed. Validate communication protocols using dedicated testing equipment.

Test with an oscilloscope to verify signal integrity and timing requirements.

Q: What protection features are included?

The system includes comprehensive protection against over-temperature, over-voltage, under-voltage, phase loss, and harmonics. These protections extend equipment service life and prevent costly failures.

Q: How quickly does the system respond to load changes?

Response time is under 30 seconds. The microprocessor controller continuously monitors your electrical system and adjusts compensation automatically.
