Application Scenarios
FAQ
Question 1: No reliable output signal after power‑on
Customer: After power‑on and wiring completion, the instrument runs normally on screen, but there is no valid voltage or current output from the terminal ports. What is the possible reason?
Manufacturer: This problem often occurs in field commissioning work, please troubleshoot step‑by‑step. First, check whether all test wires are firmly connected to voltage output, current output and terminal blocks; confirm no loose or poor contact. Second, verify test software parameter settings, ensure the output channel is enabled and output amplitude is not set to zero. Besides, check whether interlock protection condition is triggered. If the above operations cannot solve the problem, please contact us promptly, do not disassemble the device by yourself.
Question 2: Test result deviation occurs during relay calibration
Customer: The tester can output voltage and current normally, but the operating value and action time of the tested relay show obvious deviation from standard parameters. How can we fix this issue?
Manufacturer: This fault is generally caused by incorrect setting or wiring error. Please take following measures: First, double‑check wiring; ensure current loop and voltage loop are not mixed‑connected. Second, confirm test parameters including rated current, rated voltage and protection setting value are correctly input in software. Third, check binary input wiring, make sure the relay action feedback signal can be collected normally. If test lead is aging or contact resistance is too large, replace with new test cables and retest.
Question 3: Device screen freezes or crashes in long‑time continuous test
Customer: When carrying out multiple‑group relay continuous test on‑site, the tester screen freezes, keypad and trackball lose response. Does it mean main board is damaged?
Manufacturer: Please do not worry. In most cases it belongs to system temporary exception instead of hardware damage. Long‑time high‑load running or unstable external power supply may cause system halt. Recommended operation steps: Cut off AC power supply, wait several minutes, restart the whole machine. Do not operate the instrument under unstable power grid environment. If fault recurs after restarting, please contact technical support, do not open the instrument housing privately.
Question 4: Binary input signal cannot be detected stably
Customer: During protection function test, binary input channel cannot stably capture relay contact action signal, signal jumps intermittently. Is there any way to improve this situation?
Manufacturer: There are three main causes for unstable binary input signal: unreliable contact wiring, interference from surrounding strong electromagnetic field, and abnormal relay contact. It is recommended to use special signal test line for binary input connection; keep the instrument far away from high‑current equipment and high‑voltage interference source. Check whether relay contact is burnt or poorly contacted. If the problem still exists after adjustment, please describe your on‑site condition, we will arrange technical personnel for remote guidance.
Question 5: Precautions for Transportation, Handling and Field Test Operation
Customer: This six‑phase microcomputer relay protection tester is precision power test equipment. What special points should we pay attention to for on‑site test, storage and transportation?
Manufacturer: Please comply with these key requirements: First, operators must receive professional training, be familiar with relay protection test principle and instrument operation specification. Second, strictly follow wiring sequence before power‑on; double‑check voltage, current, binary input and output wiring by two personnel to avoid wrong connection damaging device or tested relay. Third, avoid violent impact and dropping during transportation; use original protective suitcase for storage and transit. Fourth, keep test environment dry, prevent dust and moisture from entering the terminal area. Fifth, store instrument in dry and ventilated place. For first‑time use, read user manual thoroughly, complete simulation test before formal field commissioning.
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
