Application Scenarios
FAQ
Question 1: Cannot download test program / Communication failure between host and test unit
Customer: I have connected all signal cables correctly. But the host cannot communicate with the relay protection tester, and test program cannot be downloaded. What is the root cause?
Manufacturer: This fault often appears in field site testing. Please perform step‑by‑step troubleshooting: first, check whether the communication cable is intact and firmly plugged in; second, confirm power supply voltage is stable, low‑voltage power supply will cause communication abnormality; third, verify digital input and output terminals are not short‑circuited. If the above checking cannot solve the problem, please contact our technical support timely, do not open the instrument housing by yourself.
Question 2: No current or voltage output during testing
Customer: The instrument powers on normally and the operation interface works well. However, there is no current and voltage output when starting relay test. How should we handle this condition?
Manufacturer: This problem may be caused by several reasons. First, check whether the external interlock protection terminal is in open state; interlock protection will block output. Second, confirm no fault alarm information exists on screen, clear fault by pressing reset button. Third, inspect output wiring terminals for poor contact or loose wiring. Do not run long‑time no‑load output. If output is still unavailable after troubleshooting, please stop testing and contact us for technical service.
Question 3: Test data deviation is large, inconsistent with expected relay action value
Customer: When calibrating numerical protection relay, the measured action value obviously deviates from standard setting value. The relay itself is in good condition. How to fix this issue?
Manufacturer: Firstly, double‑check all wiring including current and voltage output loops, wrong wiring will lead to wrong test result. Secondly, confirm parameter setting on software side matches actual relay model. In addition, check whether secondary burden of tested relay exceeds the instrument’s output load capacity. It is recommended to do regular calibration every 1‑2 years. If deviation remains, please record test phenomenon and send to our technical team.
Question 4: Touch screen malfunction, keyboard operation invalid
Customer: After power‑on, the screen displays normally, but touch response fails or part of the keyboard keys do not work. Reboot sometimes gives temporary recovery.
Manufacturer: Please cut off power completely, wait for 2‑3 minutes and restart the equipment. Unstable power supply may trigger peripheral driving exception. Do not tap screen with sharp hard objects. Avoid strong electromagnetic interference near the instrument. If the fault recurs repeatedly, internal circuit damage may exist. Please stop operation and contact us, do not attempt to disassemble the equipment.
Question 5: Precautions for transportation, field operation and daily maintenance
Customer: This relay protection tester is frequently transported among different substations. What key points should we notice for operation, storage and transportation?
Manufacturer: Please follow these important requirements: First, this test device outputs analog high‑current and high‑voltage signals; operators must obey power safety specifications. Second, avoid heavy impact and drop during transportation, internal precision modules are vulnerable. Third, store the instrument in dry and ventilated environment, keep away from damp and dust. Fourth, do not apply over‑load on current and voltage output terminals for long time during test. Fifth, regular calibration every 1‑2 years is required to guarantee test accuracy. All operations shall be completed by professional power testing personnel.
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
