Frequently Asked Questions (FAQ)
Q1:What is the difference between the power factor control mode and the reactive power control mode?
A1: The Intelligent Reactive Power Auto Compensation Controller operates in these two modes based on the PA-4 parameter setting. The power factor mode is preset at the factory and is suitable for standard applications. The reactive power mode provides precise control of capacitor bank switching without oscillations, which is especially suitable for large-capacity scenarios. However, users must input the actual CT ratio and capacitor capacity in this mode.
Q2:Why does the controller display "C-0" during operation?
A2: The controller displays "C-0" when the signal current input is too small (less than 60mA) or absent. Users should check if the current transformer ratio selection is reasonable. Users must also verify that the current signal circuit has no open circuit or other instruments connected in series.
Q3:Why does a capacitor bank never get switched on in reactive power mode?
A3: A capacitor bank is never switched on in reactive power mode when its capacity parameter is preset to "0" or set too large. Users can resolve this issue by resetting the capacity parameter correctly in the controller's menu.
Q4:Does Geyue Electric offer customized specifications for this product?
A4: Yes, Geyue Electric provides customized specifications such as oscillation locking, 220/110V voltage, and 60Hz frequency. Our engineering team can tailor the controller to meet your specific distribution system requirements.
Q5:What is the minimum order quantity (MOQ) for this controller?
A5: Our standard minimum order quantity is typically 1 piece for sample evaluation. However, we offer competitive wholesale pricing for bulk orders. Please contact our sales team for specific MOQ requirements based on your project needs.
Q6:What is the delivery time for bulk orders?
A6: The delivery time usually ranges from 7 to 15 working days after receiving the deposit. It depends on the order quantity and specific customization requirements. We will provide an exact lead time upon order confirmation.
Q7:What kind of warranty and after-sales support do you provide?
A7: Geyue Electric offers an 18-month warranty for the Intelligent Reactive Power Auto Compensation Controller. Within 3 months from the date of shipment, we promise to replace the old machine with a new one for any quality problems. We also provide continuous engineering support for remote diagnosis, parameter setting, and fault handling.
Q8:Are you a manufacturer or a trading company?
A8: Geyue Electric is a professional manufacturer dedicated to independent research and continuous innovation of low-voltage reactive power compensation technologies. We have a highly experienced engineering team specializing in power electronics, electrical automation, and field applications.
