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.

Before ordering the TEST-905, verify its compatibility with your existing test equipment and the specific requirements of your protection schemes. Confirm the maximum current and voltage ratings of the CTs or relays you intend to test, as exceeding these limits can damage the equipment or yield inaccurate results. Request a detailed specification sheet to cross-check technical parameters such as output stability, waveform distortion, and measurement accuracy.
For logistics, confirm whether the supplier provides export packaging that meets international shipping standards, as the unit’s weight and dimensions may require specialized handling. Clarify the Incoterms offered by Beijing Gfuve Electronics Co., Ltd., as this will determine who bears the cost and risk of transport. Typical options for this type of equipment include FOB Beijing or CIF to the buyer’s port, with lead times varying based on production schedules.
Quality checks should include a pre-shipment inspection to verify the unit’s calibration and physical condition. Request a factory test report or third-party calibration certificate to ensure the TEST-905 meets its specified performance criteria. For customs clearance, confirm that the supplier can provide the necessary documentation, such as a commercial invoice, packing list, and CE or ISO certificates if applicable. Insist on a demonstration or trial period to validate performance in your specific use case.
