All transformers and choke products are subjected to 100% final inspection of electrical and mechanical data. Our standard electrical tests include no-load currents and no-load voltages; 4000VAC Hi-Pot test for 2 seconds between primaries and secondaries. Winding resistance's are verified on every production lot. Visual inspection includes physical dimensions and appearances. Additional tests can be specified by customer, such as maximum level of magnetic strayfields, mechanical hum, leakage current, voltage and current data under load, etc.
Unless otherwise specified by the customer, transformers and mounting hardware are packed in re-enforced, heavy duty double-wall corrugated cardboard boxes with a total weight of 25-30 Lbs. for easy handling. Larger shipments are palletized for motor carrier.
