FAQ
Question 1: Abnormal travel & speed test data / Large measurement deviation
Customer: When testing vacuum and SF6 circuit breakers, the measured travel and opening-closing speed data have big deviation compared with factory technical parameters, what brings about this issue?
Manufacturer: Check whether the displacement sensor is firmly mounted and aligned accurately with the moving contact of circuit breaker first. Ensure the sensor bracket and magnetic base will not shift during breaker operation. Confirm you have selected the matching breaker type on the instrument menu. Complete zero calibration before formal test. Inspect sensor cable for damage or poor contact. Retest after adjusting all settings. If deviation still exists, stop testing and contact technical support. Do not open cabinet for self-repair.
Question 2: No signal collected / No waveform displayed on screen
Customer: After finishing wiring work, the tester fails to capture timing signals, and no waveform appears on screen when the circuit breaker executes opening or closing action, how to troubleshoot?
Manufacturer: Check the connection state of switch control line and breaker coil. Confirm external triggering line is properly connected, and all clips have clean contact surface without oxide or dirt. Verify the breaker control voltage matches the instrument output range. Inspect test cables for breakage. Restart instrument and redo the whole wiring setup. If the fault cannot be eliminated, stop operation and contact manufacturer support. Do not open cabinet for self-repair.
Question 3: Failed DC power output / Cannot drive breaker coil
Customer: The instrument cannot output adjustable DC 30~250V power and 20A instantaneous current during site test, so it cannot drive the circuit breaker coil to complete switching action, what should we check?
Manufacturer: Confirm input 220V power supply is stable and power cord connection is tight. Check whether the built-in fuse is blown caused by instantaneous current impact. Verify no short circuit or overload exists on output terminals. Avoid using the tester under over-humid or ultra-high temperature environment which triggers power module protection. Restart instrument to reset protection program. Replace fuse with specified spare part if needed. If the problem persists, stop operation and contact technical support. Do not open cabinet for self-repair.
Question 4: Big three-phase synchronization error / Fail substation acceptance
Customer: Three-phase synchronization test result shows obvious error and cannot satisfy substation handover acceptance standard, what are the possible reasons?
Customer: Check all three groups of test wires are connected reliably, and inconsistent wire length will not interfere signal acquisition. Confirm three phases’ sensor installation positions are consistent. Check the breaker operating mechanism without mechanical jam or rust. Ensure testing environment temperature and humidity are within specified working range. Recalibrate instrument before retesting. If the error still exceeds limit, stop field test and contact technical support. Do not open cabinet for self-repair.
Question 5: Thermal printer fails to print test report
Customer: After finishing dynamic characteristic test, the built-in thermal printer cannot print test report and waveform curve, what can we do?
Manufacturer: Check if thermal printing paper is loaded in the correct direction. Confirm the paper is standard thermal paper and keep dry without dampness. Check the printer roller is clean and not stuck by foreign debris. Restart the print function. If there is no response, power off and reboot the whole instrument. Do not disassemble printer module privately. If printing still fails, 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
