Description

Megger Delta 4310 Power Factor Test Set Repair

The Megger Delta 4310 is an insulation power-factor / dissipation-factor (tan-delta) test set — it energizes transformer, bushing, and cable insulation at 12 kV and measures capacitance and dielectric loss to assess insulation condition. It pairs an HV source with a precision loss/capacitance bridge, so faults span the HV side and the sensitive measurement side — not the cable-locator/TDR faults its category label implies.

June Company repairs and calibrates the Megger Delta 4310 for transformer-maintenance and insulation-diagnostics crews.

Common Megger Delta 4310 problems we fix

Power-factor / tan-delta readings off — drift in the loss-measurement bridge, the critical function, recalibrated against standards.
HV output low or unstable — the 12 kV source degrading, repaired for stable test voltage.
Capacitance readings inaccurate — the capacitance path, corrected.
Won’t connect or download — interface faults to the test PC.
Display or control faults.

FAQs

My tan-delta numbers look wrong — repairable? Yes. Power-factor accuracy drift traces to the measurement bridge; we repair and recalibrate it so insulation condition assessments are trustworthy, with a NIST-traceable certificate.

Is the HV output verified? Yes — test voltage is checked along with 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.
