Description
ISA STS 5000 Substation Test Set Repair
The ISA STS 5000 is a multifunction substation test system — it combines relay testing, with high-current and high-voltage sources and precision measurement, to commission and maintain protective relays, CTs/VTs, and substation equipment. As a multi-source, multi-measurement system, its faults span the output (amplifier/source) stages, the measurement channels, and the control electronics.
June Company repairs and calibrates the ISA STS 5000 for substation commissioning and relay-test crews.
Common ISA STS 5000 problems we fix
- Output-stage rebuilds — a voltage or current source weak or dead, repaired so every source meets rated output.
- Measurement-channel recalibration — measurement inputs drifting, recalibrated against standards.
- Timing / phase accuracy off — the timing and phase reference, corrected.
- Won’t connect to the control PC — interface faults, repaired.
- Display, control, or power faults.
FAQs
One of my STS 5000 sources is down — fixable? Yes. Output-stage failure is repairable, then all sources and measurement channels are verified against our standards with NIST-traceable calibration.
Are timing and phase verified? Yes — checked and certified along with the sources.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
