Application Scenarios
FAQ
Question 1: Output current value has large deviation compared with standard test data
Customer: When calibrating relays and circuit breakers on site, the tester operates normally without alarms, but the output current value has obvious deviation from standard reference data. What should I check?
Manufacturer: First, check all high-current output cables and grounding wires to ensure correct connection without wrong wiring or missing grounding. Second, inspect the test terminal clamps; oxidation, paint residue and loose contact will cause resistance difference and current deviation, clean and fasten all clamps tightly. Third, confirm the tester works within standard short-time working cycle without overheating. Finish the above inspections and retest. If deviation still exists, professional instrument calibration is required.
Question 2: Tester current boosting fails during primary injection test
Customer: The instrument powers on normally and all indicators show normal status, but the device cannot boost current and fails to complete relay and circuit breaker calibration test. How to solve this problem?
Manufacturer: Incorrect loop connection is the main cause. Confirm the tested circuit breaker and relay form a completely closed test loop without open circuit. Check whether the power input voltage is within the standard 220V±10% range. Verify the over-temperature protection function is not triggered due to frequent continuous tests. Restart the instrument, reconnect the test cables strictly according to the operation manual, and perform the test again.
Question 3: Instrument displays normally but cannot launch high-current test
Customer: The tester boots successfully with normal screen display and button response, but no current output after pressing the start test button and cannot start the testing procedure.
Manufacturer: Check whether all output terminals and test clamps achieve reliable electrical contact without virtual connection. Confirm the correct current gear and test mode are selected according to the test object. Eliminate strong on-site electromagnetic interference from adjacent live equipment. Reboot the entire instrument system. If the fault persists after all operations, stop testing and contact manufacturer technical support, do not disassemble the equipment privately.
Question 4: Tester overheats quickly and triggers current limiting protection
Customer: The tester works normally at the first test, but it heats up rapidly during intermittent tests and automatically limits current output, affecting continuous calibration work.
Manufacturer: Confirm strictly with the equipment short-time working standard. Single high-current test time should not exceed 2.5 minutes. Avoid continuous repeated tests without cooling interval. Check whether the equipment ventilation holes are blocked by dust or sundries. Place the tester in a dry and ventilated environment for heat dissipation. Stop the test for 10 minutes for full cooling before restarting the next test.
Question 5: Field operation precautions for high current primary injection tester
Customer: We often use this high current injection tester for relay and circuit breaker calibration in substation sites. What key safety and operation precautions need to be followed?
Manufacturer: Ensure the tested relay, circuit breaker and primary loop are completely de-energized and reliably grounded before connecting test cables. Never plug or unplug test clamps during current output operation. Avoid testing in high humidity, rainy and heavy dust environments. Arrange high-current cables neatly to prevent extrusion, pulling and short circuit. Save test data timely after each test before powering off. Stop all test work and disconnect the equipment immediately if thunderstorm or strong electromagnetic interference occurs on site.
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
