Description
Tettex 2881 Power Factor Tester Repair
The Tettex 2881 is an insulation power-factor / tan-delta test set — it energizes transformer, bushing, and cable insulation at high voltage and measures dielectric loss to assess condition. It pairs an HV source with precision loss measurement, so faults fall on both the HV side and the sensitive tan-delta measurement side.
June Company repairs and calibrates the Tettex 2881 for insulation-diagnostics specialists and HV maintenance crews.
Common Tettex 2881 problems we fix
- Tan-delta / power-factor readings off — drift in the loss-measurement circuit, the critical function, recalibrated against our standards.
- HV output low or unstable — HV source degradation, repaired for stable test voltage.
- Capacitance readings inaccurate — the capacitance path, corrected.
- Interface or download faults — connection to the test PC.
- Display or control faults.
FAQs
My power-factor results look wrong — repairable? Yes. Tan-delta accuracy drift traces to the measurement circuit; we repair and recalibrate so condition assessments are trustworthy, with a NIST-traceable certificate.
Is the HV output verified? Yes — test voltage is checked alongside the loss measurement.
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.
