FAQ

Q1: What equipment and occasions is this automatic capacitance & inductance tester suitable for?
Customer: What equipment can this tester measure? Is it designed for substation capacitor banks?
Manufacturer: Yes. This three-phase automatic capacitance & inductance tester is specially designed for field measurement of shunt capacitor banks, capacitor units, and inductive components in substations and power plants. It is widely used in preventive tests, handover tests after installation, and post-maintenance checks of high-voltage capacitor installations. The tester performs three-phase measurement at one time, and can measure both capacitance (μF) and inductance (mH/H) of the tested equipment, which effectively reflects the insulation condition and internal state of capacitor units, helping to detect capacitance deviation, insulation degradation or element failure in time.
Q2: What are the measurement range, accuracy and key technical specifications?
Customer: What is the capacitance measurement range of this tester? What about the accuracy? Does it support three-phase testing?
Manufacturer: The tester has a wide capacitance measurement range of 0.1μF to 3300μF, covering most capacitor units and capacitor banks used in substations. The measurement accuracy is ±1%, ensuring reliable and repeatable results for both capacitance and inductance measurement. It supports three-phase automatic measurement, which means you can test phase A, B and C of a capacitor bank without repeated wiring. The instrument is powered by AC 220V 50Hz, adopts a panel-type structure with built-in display and keypad, and is packed in a rugged yellow carrying case for convenient field transportation.
Q3: How to control the tester and manage the test data?
Customer: Does this tester support computer connection? Can I control it remotely and export test data?
Manufacturer: Yes. The tester is equipped with a USB interface for PC control: you can connect it to a computer with the USB cable, and the supporting upper-computer software allows you to start tests, set parameters and read results remotely. The instrument also provides RS-232 serial communication interface for industrial integration. Measured data can be saved in the internal memory and exported to the computer for archive management; the exported data can be used to generate complete test reports and track the long-term trend of capacitance deviation, which is convenient for equipment condition assessment and preventive maintenance planning.
Q4: What should be noticed for on-site wiring, discharge and operation safety?
Customer: What safety points should I pay attention to when testing capacitor banks in the substation? Do I need to discharge the capacitors before testing?
Manufacturer: Safety first. Please strictly follow these points: First, before testing, the capacitor bank must be completely disconnected from the power supply and fully discharged; capacitors may retain dangerous residual voltage, so discharge them through the discharge rod and confirm zero voltage before connecting the test leads. Second, confirm that the test clamps are firmly connected to the capacitor terminals and the contact surface is clean, otherwise the measurement result will be affected. Third, during the test, do not touch the test clamps and cables to avoid electric injury. Fourth, keep the instrument away from strong electromagnetic interference sources and avoid operating in rain or high humidity. After the test, disconnect the test leads in time and restore the equipment according to the operating procedures.
Q5: Shipping Method
Customer: If we place an order, how do you typically ship the goods? Will there be any issues with transporting bulky items such as reactors?
Manufacturer: We default to using dedicated logistics lines or brand-specific express shipping services; small-sized main units and accessories may also be shipped via standard courier services. Large items, such as reactors and excitation transformers, are packed using wooden crates or wooden frames for reinforcement to prevent bumps and moisture exposure during transit; a packing list is included with each package to facilitate item-by-item counting for you. Logistics costs are typically determined by both parties in accordance with the contract terms; after shipment, we will send you both the tracking number and the carrier's contact phone number for easy tracking.If your project site is remote or if delivery to the site is required with a specified logistics company, please inform us in advance when placing your order; we can then coordinate and arrange accordingly.
Q6: Delivery Lead Time
Customer: Our project is under tight deadlines; how long will it take for the order to be shipped after we place it? Can we request expedited shipping?
Manufacturer: Standard specifications – stock available; typically delivered upon receipt of the order. Orders can be shipped within [X] working days; for non-standard products requiring customized voltage levels, capacities, or reactor combination configurations, the production cycle typically ranges from [X] to [Y] days.The delivery time will be approximately 7-15 working days; the specific timeline shall be subject to the sales confirmation provided upon order placement. If your project has a tight schedule, please inform us of the latest expected delivery date before placing your order; we will first verify the production schedule and inventory status, and where possible, will coordinate expedited production and prioritize shipment. However, it is recommended to allocate sufficient transit time for logistics to avoid delaying on-site testing.
Q7: After-sales Service and Warranty
Customer: What is the warranty period for this equipment? If any issues arise during on-site use, how will your after-sales service respond?
Manufacturer: We provide a two-year free warranty on the entire unit and lifelong technical support services. During the warranty period, if issues arise due to defects in the equipment itself, we will provide free repair or replacement of components; when problems occur on-site, we commit to responding within 24 hours; most wiring and parameter configuration issues can be resolved through remote guidance via video or telephone; for cases where an on-site visit is necessary, we will arrange for our technicians to arrive at the location to resolve the issue. After the warranty period expires, we still offer repair services, with spare parts supplied at cost price for the long term, and software updates provided free of charge for life. Upon delivery of the equipment, we also offer free operational training (video operation guides)to ensure that your testing personnel can operate the equipment independently and proficiently; should you have any further questions, please feel free to contact our dedicated after-sales hotline directly.
Q8: Shipping methods for each region (Sea freight)
Customer: Our projects are distributed across several states, and our procurement volumes are substantial; are the shipping methods consistent across all states? How is the delivery time calculated?
Manufacturer: The specifications are identical; however, it should be specifically noted that this equipment set is large in size and heavy in weight—components such as the reactor and excitation transformer are all classified as heavy components. Therefore, regardless of which state or region the shipment is destined for, we will uniformly utilize sea freight transportation. The packaging employs export-grade wooden crates with reinforced structures, along with moisture-proof and rust-proof treatments; the design of these wooden crates is optimized for long-distance sea transport and multiple lifting and transshipment operations. Upon arrival at the destination, simply unpack the goods and conduct an inspection before putting them into use. Regarding delivery time, the sea freight transit period depends on the port of destination: near-sea routes are generally faster, whereas ocean routes may take longer; the exact number of days will be confirmed based on the shipping schedule specified in the bill of lading. We have a dedicated freight forwarding agency to handle booking of shipping space, customs declaration, insurance, and other related procedures; once the vessel departs, we will send you documents such as the bill of lading and the packing list, enabling you to arrange for the receipt of goods at the port of destination and their inland transshipment in advance
