Description
SMC Raptor-HV Primary Injection Repair
The SMC Raptor-HV Primary Injection is a protective relay test set – it generates precisely controlled voltages and currents, and times how a protection relay responds. High-current amplifiers driven hard into inductive loads are the heart of it, and the part that wears.
Certified technicians at June Company service the SMC Raptor-HV Primary Injection for utility relay technicians, substation commissioning crews, and industrial protection teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common SMC Raptor-HV Primary Injection problems we fix
- Phase angle accuracy drifted.
- Trip timing measurement errors.
- Binary input or output faults.
- IEC 61850 or GOOSE communication failures.
- Convertible channels not combining.
- Cooling fan or thermal shutdown.
- Internal power supply faults.
- Display, keypad or front-panel faults.
- One current or voltage channel weak or dead – amplifier output-stage failure in a single channel while the others still work, which is the classic giveaway.
FAQs
Do you service instruments past manufacturer support? Yes. Much of what we repair is out of support, which is exactly where component-level work earns its keep.
What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
