FAQ

Question 1: Abnormal bounce‑time data is displayed after completing circuit breaker test
Customer: When we test high‑voltage circuit breakers on‑site, the measured contact bounce time is far beyond the allowable range, while other time parameters show normal values. What should we check?
Manufacturer: Excessive bounce reading is mostly caused by mechanical wear or improper sensor installation. First, inspect the moving and static contacts of circuit breaker for burning, ablation or insufficient lubrication. Second, check whether the displacement sensor is firmly locked without looseness during breaker movement. Third, check signal cables for poor contact, broken core wire or oxidized connector. Re‑install and fasten the sensor, then perform retest. If bounce value is still out‑of‑specification after above operations, the circuit breaker operating mechanism needs disassembly maintenance. Do not continue field acceptance test before mechanical repair.
Question 2: Tester sends opening/closing command, but the circuit breaker cannot perform corresponding action
Customer: We finish all wiring according to manual, trigger close or open command from tester, however the high‑voltage circuit breaker has no response at all. How to troubleshoot this fault?
Manufacturer: Please follow step‑by‑step inspection. Firstly, confirm the excitation wiring for opening and closing coil is correctly connected without reversed polarity. Secondly, verify the coil rated voltage setting on instrument menu matches actual coil voltage of tested breaker. Thirdly, check whether breaker control loop power supply is normal and the coil itself is not burnt‑out. Fourthly, confirm trigger mode selection in software is consistent with actual test requirement. After adjusting wiring and parameters, send operation command again. Avoid frequent continuous triggering within short period to prevent coil burnout.
Question 3: Large deviation exists in travel and velocity test results among repeated measurements
Customer: Multiple repeated tests for the same circuit breaker get obviously different travel and velocity data, test result lacks repeatability. What brings about this phenomenon?
Manufacturer: This problem mainly relates to sensor fixing and breaker mechanical state. Check if the displacement sensor mounting bracket and magnetic stand slip during breaker action; loose installation will directly cause unstable sampling. Confirm the sensor measuring head keeps reliable contact with breaker moving shaft, without offset or bouncing away. Meanwhile, check whether the circuit breaker mechanism lacks lubrication and exists jamming resistance. Make sure the breaker operates flexibly. Fix sensor rigidly and lubricate mechanism properly, then carry out groups of repeated tests.
Question 4: No waveform and parameter data output after test starts
Customer: Instrument powers on normally, touch screen works well, we start test procedure, but no test waveform and measured parameters appear after breaker completes opening‑closing action.
Manufacturer: Confirm signal cables between tester and displacement sensor are fully plugged in, no loose or disconnected terminals. Check whether sensor type selection inside software matches the actual equipped sensor. Inspect if the sensor measuring head moves synchronously along with breaker transmission shaft during switching action. If external wiring and installation are normal but still no data collected, restart the whole instrument. If failure remains, stop operation and contact manufacturer technical support, do not disassemble instrument shell by yourself.
Question 5: What environmental and pre‑test requirements for on‑site substation test?
Customer: We often carry out breaker characteristic test in substation field, what conditions should we pay attention to before and during measurement?
Manufacturer: The circuit breaker must be under complete power‑off maintenance status, reliable earthing is required before all connection work. Keep instrument and signal cables far away from high‑voltage live equipment to reduce strong electromagnetic interference. Do not place the tester under direct heavy rain or high‑humidity environment. All excitation wires and sensor cables should be arranged tidily, avoid pulling and squeezing cables. After finishing each group of tests, save test reports before power‑off the device. If thunderstorm weather occurs on site, terminate test work immediately and disconnect instrument from external circuit.
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
