FAQ

Q1: What tests can this CT/PT comprehensive tester perform?
It can complete excitation (volt-ampere) characteristic test, transformation ratio test, polarity check, DC winding resistance measurement and secondary load test for both current transformers (CT) and voltage transformers (PT), covering routine power acceptance inspection items.
Q2: Is external booster equipment needed during testing?
No extra booster or voltage regulator is required. The built-in variable frequency boost module is integrated inside the host, which simplifies field wiring and avoids bulky auxiliary devices.
Q3: How to prevent wrong wiring during operation?
Standard CT & PT wiring diagrams are printed clearly on the panel, with terminals divided by functions and marked with S1, S2, P1, P2, M1, M2 separately. Color-coded test cables further reduce wiring errors effectively.
Q4: Why does the test curve appear abnormal or data fluctuate?
Recheck and tighten all test cable clips to remove surface oxidation; confirm no open circuit or short-circuit fault on the secondary winding of the transformer; restart the measurement after troubleshooting.
Q5: Shipping Method
If we place an order, how do you typically ship the goods? Will there be any issues with transporting bulky items such as reactors?
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.
Q6: Delivery Lead Time
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?
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.
Q7: After-sales Service and Warranty
What is the warranty period for this equipment? If any issues arise during on-site use, how will your after-sales service respond?
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.
Q8: Shipping methods for each region (Sea freight)
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? 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
