FAQ

Question 1: What test functions can this three‑phase capacitance and inductance tester realize?
Manufacturer: This instrument supports both single‑phase and three‑phase measurement modes, it can test capacitance and inductance values of power capacitors, capacitor banks and reactors on‑site. It adopts no‑disassembly testing technology, there is no need to remove connecting wires of parallel capacitor banks, greatly improving field working efficiency. Besides capacitance and inductance, it can collect related parameters including voltage, current and phase angle. Equipped with built‑in thermal printer, it can print complete test reports directly on site. Mass test data can be stored in local memory, users can query historical records and export data via USB port. It is widely used for acceptance inspection and routine maintenance work in substations and capacitor‑compensation stations.
Question 2: Why are the measured capacitance values inconsistent with nameplate parameters of capacitor bank?
Manufacturer: Multiple field factors may cause data deviation. First, check whether test cables and clamp current sensor are firmly connected, poor contact, loose clips or oxidized terminals will bring obvious measuring error. Second, confirm that the tested capacitor bank is completely power‑off and fully discharged; residual voltage will interfere with test accuracy. Third, check for external electromagnetic interference from surrounding high‑voltage equipment, keep test cables away from high‑voltage live lines as far as possible. If individual unit inside capacitor bank has partial failure or capacity attenuation, the overall measured value will also deviate from theoretical nameplate value. After checking above‑mentioned items, if deviation still exists, please contact manufacturer technical support, do not disassemble the instrument housing by yourself.
Question 3: Can this device perform no‑disassembly test for mixed‑connected capacitor banks? What test prerequisites should be noticed?
Manufacturer: It is applicable for most parallel‑connected capacitor banks to carry out no‑disassembly measurement. But the capacitor bank must be completely de‑energized and fully discharged before testing, live testing is strictly forbidden. For complex mixed series‑parallel special capacitor groups, partial wiring structure may affect measuring accuracy, users should evaluate feasibility before testing. In addition, keep sufficient safety distance between instrument and high‑voltage equipment on‑site, avoid strong electromagnetic field direct radiation to test leads. If the on‑site interference signal is extremely strong, switch to single‑phase measuring mode and increase averaging times to get stable test results.
Question 4: What should we do if instrument screen displays abnormal reading or data fluctuates greatly during field test?
Manufacturer: When data keeps jumping and cannot get stable reading, follow these troubleshooting steps. Firstly, inspect the clamp current sensor: confirm sensor jaw is completely closed without sundries, dirt or gap, and the sensor connecting cable is intact without breakage. Secondly, check alligator clip test cables, make sure clips are clamped on correct measuring terminals reliably. Thirdly, restart the tester, run built‑in self‑check program to verify hardware status. Besides, heavy‑duty electromagnetic interference at substation site is a common cause of data fluctuation. You can shorten test cables properly or rearrange cable routing away from high‑voltage equipment. If fault cannot be eliminated after all operations, stop test and send feedback to supplier.
Question 5: What are the requirements for daily maintenance, storage and calibration cycle of this tester?
Manufacturer: After finishing field test work, clean test cables, alligator clips and clamp current sensor, wipe off dust and dirt. Avoid pulling and twisting cables violently. Store whole set inside the matched hard protective case, place in dry, ventilated room, prevent moisture, heavy extrusion and sun exposure. It is recommended to send the instrument to qualified metrology laboratory for professional calibration once every 12 months. If the instrument works frequently under harsh substation environment, shorten calibration cycle to every 6 months. Before important acceptance test, complete full set self‑inspection for host, sensor and test accessories to guarantee measuring reliability.
Question 6: 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.
Question 7: 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.
Question 8: 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.
Question 9: 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
