从China供应商批发进口5000a Testing Primary Current Injector — FOB条款

The TEST-905 primary current injection system is a precision instrument designed for on-site and laboratory testing of current transformers, circuit breakers, and protection systems. It employs an ARM-controlled toroidal transformer to deliver large current outputs, with a maximum rating of 5000A. The unit features an LCD display that shows primary and secondary current values, turn ratio, and phase shift simultaneously, enabling accurate verification of CT performance and polarity under test conditions.

Constructed with an aluminum alloy body and a PC panel enclosure, the TEST-905 is built for durability in industrial environments. Primary current injectors in this class are typically used to verify relay settings, test busbar protection schemes, and validate the accuracy of high-ratio CTs. Standard models in this category often support output ranges from 1A to 6000A, with resolution down to 0.1A, and include overcurrent and overtemperature protection as typical safety features. This model integrates these functions with a compact, portable design weighing approximately 50kg, suitable for field deployment.

This system is primarily sourced by utilities, electrical contractors, and testing labs that require repeatable, high-current injection for commissioning and maintenance. It is particularly valuable for verifying protection schemes in substations and switchgear, where precise current and phase relationship measurements are critical. Buyers should confirm compatibility with their existing test setups, as the unit’s output characteristics must match the input requirements of the protection relays or meters under test.

Beijing Gfuve Electronics Co., Ltd. is based in Chaoyang District, Beijing, with its registered address at 01117-8 Fortune Street No.67 Chaoyang Rd. The company specializes in electrical testing equipment, including current injectors and related systems for power system applications. Its profile indicates an imported tier classification, suggesting it sources or assembles components internationally to meet technical standards.

The supplier’s trust tier is marked as harbor, which reflects a baseline verification level for new or less active accounts. As of the latest data, the company has a 0.00% response rate with no recorded average response time, indicating limited engagement history on the platform. Buyers are advised to contact the supplier directly to confirm technical support availability and lead times for custom configurations.
