FAQ
Question 1: Large measurement error / Test data exceeds 0.5% accuracy range
Customer: The measured dynamic parameters of the circuit breaker show obvious error and the result exceeds the instrument's 0.5% accuracy specification, what leads to this problem?
Manufacturer: Check the installation of the displacement sensor first, ensure the sensor bracket and magnetic base are tightly fixed without shifting during the movement of the circuit breaker contact. Complete zero calibration before the formal test and select the correct breaker type on the instrument menu. Avoid strong electromagnetic interference and excessive vibration in the test site. Confirm the ambient temperature and humidity are within the allowable working range. Retest after adjusting all setup. If the error still fails to meet the standard, stop testing and contact technical support. Do not open cabinet for self-repair.
Question 2: No trigger signal / No waveform collected during breaker action test
Customer: After all wiring is finished, the instrument cannot capture trigger signals and no waveform appears on the screen when the high voltage breaker performs opening and closing operation, how to troubleshoot this fault?
Manufacturer: Inspect the external triggering line and fracture signal cables, check for loose connection, broken wire or oxide on the alligator clips. Confirm the coil control wiring matches the instrument output port. Check whether the input 220V power supply is stable without voltage fluctuation. Restart the analyzer to clear system cache, then redo wiring and test. If the signal is still unavailable, stop operation and contact manufacturer support. Do not open cabinet for self-repair.
Question 3: Failure of adjustable DC output / Cannot actuate breaker operating coil
Customer: The analyzer cannot output normal adjustable DC voltage to drive the circuit breaker coil in field test, the breaker cannot complete opening or closing action, what should we check?
Manufacturer: Check the power input cable and confirm the 220V power source is well connected. Inspect the built-in fuse for burnout caused by instantaneous current surge. Verify there is no short circuit or overload on the output terminals. Do not operate the device in damp environment which will trigger power module protection. Reboot the instrument to reset internal protection circuit. Replace the fuse with the specified spare part if needed. If the output still fails, stop operation and contact technical support. Do not open cabinet for self-repair.
Question 4: Inconsistent three-phase data / Poor synchronization test result
Customer: The three-phase synchronization test data has large differences between phases and cannot pass substation handover acceptance, what are the possible causes?
Manufacturer: Check all three groups of test wires for reliable connection, ensure the wire length difference will not bring signal distortion. Keep the installation position and angle of three-phase sensors consistent. Check the breaker operating mechanism to rule out mechanical jamming or rust. Remove dust and dirt on contact points to guarantee stable signal transmission. Recalibrate the instrument before retesting. If the synchronization error remains too big, stop field test and contact technical support. Do not open cabinet for self-repair.
Question 5: Failed data export / Cannot save test waveform and report
Customer: After finishing the dynamic characteristic test, the instrument cannot save test waveform data and cannot export formal reports for project filing, how to solve this problem?
Manufacturer: Check if the USB flash drive is recognized by the analyzer, replace a compatible USB storage device if identification fails. Do not cut off power supply forcibly during data recording. Check the internal storage space of the instrument to prevent saving failure caused by full memory. Reboot the equipment to fix system program bugs. Repeat the test and save files after all settings are confirmed normal. If export function still does not work, stop operation and contact technical support. Do not open cabinet for self-repair.
Question 6: 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.
Question 7: 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.
Question 8: 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.
Question 9: 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
