Primary Injection Test Sets Manufacturer and Supplier
Primary injection test sets inject a high primary current through a current transformer and its connected protection circuit, so that the whole chain — transformer, wiring and relay — can be checked together, rather than testing the relay alone by secondary injection.
The key selection figure is the primary current the set must deliver, together with the test functions needed: CT ratio and polarity, circuit breaker timing, and temperature rise testing on larger sets. Before ordering, confirm the model, the primary current range, the test functions, and the delivery terms.

Figures on this page come from the manufacturer's own category pages, manufacturer-hosted datasheets, or a shop listing stated as such. Where the reference material does not settle a figure, this site states that it is unresolved and publishes no figure, rather than choosing one.
What to confirm before ordering
Before payment, confirm the model, the specification from the current datasheet, the quantity, the price, the lead time, and the delivery terms, in writing. Ask in your inquiry to confirm the payment terms, the trade terms, and the reply time you should expect, rather than assuming any of them. No price, minimum order or lead time figure is stated on this site.
Send an inquiry: include the model, the test or measurement requirement, and the quantity you need. Before payment, confirm the model, the specification from the current datasheet, the quantity, and the delivery terms.
