Import 3000a Primary Current Injection Test Equipment — Buy in wholesale FOB from Supplier in China

The 3000A Primary Current Injection Test Equipment from Beijing Gfuve Electronics Co., Ltd. is a bench and field-deployable unit built to inject up to 3000 A into primary circuits for protective relay and circuit breaker testing. The unit carries a digital display interface and is housed in a portable chassis with overcurrent protection as a built-in safeguard. Output current range, duty cycle, and accuracy class are not stated in the source material and should be requested directly from the supplier before technical evaluation.

Primary injection testing at this scale typically employs a tapped or electronically regulated current source with copper busbar terminations and forced-air cooling to sustain thermal limits during extended injection sequences. The 3000 A rating implies suitability for medium-voltage switchgear and substation protection verification where secondary injection alone cannot validate CT polarity, ratio, or saturation characteristics. Standard industry practice for such equipment includes compliance with IEC 60255 and IEEE C37.90 test procedures, though buyers should verify which editions the unit was evaluated against.

Utilities, relay service companies, and large industrial maintenance teams use this equipment for commissioning, periodic protection audits, and fault-scenario validation. The portable form factor suggests deployment across multiple substations without fixed installation. Payment and shipping terms listed in the source reference L/C and T/T instruments, though exact lead times, calibration certificates, and spare-part availability are not specified and must be confirmed with Beijing Gfuve Electronics Co., Ltd.

Beijing Gfuve Electronics Co., Ltd. is located at Fortune Street No.67, Chaoyang Road, Beijing 100025, China, placing its operations within the Chaoyang district of the capital. listings classify the supplier under an imported tier with a harbor trust designation, which in marketplace terminology indicates a baseline verification profile rather than an audited or third-party certified status. The response rate shown is 0.00% with zero average response hours recorded, meaning prospective buyers should not assume prompt communication and should plan sourcing timelines accordingly.

The supplier profile does not disclose year of establishment, production floor space, headcount, revenue, client references, or ISO 9001 registration certificates. No information is provided about in-house calibration laboratories, after-sales service networks, or spare-parts stocking. Buyers are advised to request a factory profile, recent test reports for the 3000A injection set, and references from utility or relay-service end users before committing to an order. The source description mentions ISO and CE compliance, but certificate numbers, scopes, and issuing bodies are absent and must be verified independently.
