EWIS RAT Patented!

Lectromec recently received notification that the EWIS RAT and associated technologies have received a patent through the US Patent Office.

Lectromec looks forward to advancing these technologies to provide increased analysis capabilities for both new and existing aircraft systems.

Lectromec at the Aging Aircraft Conference

Lectromec presented a paper at the 2009 Aging Aircraft Conference on "Arcing Damage to Aircraft Components and Wire at a Distance". This will be posted on here within the next month.

Electrical Arcing

Lectromec offers both Wet and Dry Arc Track Resistance testing conducted in accordance with the May 1994 draft test method 3006 of MIL-STD-2223 for the Wet Arc Track Resistance test and method 3007 of MIL-STD-2223 for the Dry Arc Track Resistance test and has recently completed the construction of a first of its kind Arc Track Unit in compliance with emerging European test standards (EN 3475-603, EN 3475-604, and EN 3475-605). Additionally, Lectromec's in-house testing services are performed according to the SAE standards 4.5.9-Method 509 (Wet Arc) and 4.3.1-Method 301 (Dry Arc). Lectromec has also conducted tests which meet European standards mentioned above. These tests provide an assessment of the ability of wire insulation to maintain its integrity while under electrical load. In service, electrical arcs may originate from a variety of factors including insulation deterioration, faulty installation, chafing and trauma. Arcs may further be induced by water or other fluids which create conductive paths on the wire's surface. Temperature, humidity and strain are all environmental factors which may contribute to the degradation of wire insulation.

Lectromec can perform Wet and Dry Arc Resistance testing on wire bundles supplied by the customer or can prepare test bundles at the customer's request. For those creating or developing wire harness protection schemes, the arc track testing services provided by Lectromec can prove an excellent means of independent verification and the quality/durability of your product.

During the test the wire bundle will be video taped using standard video taping equipment. Further, "still" photographs will be taken of the test set-up and of important events that occur during the test. The electric currents and arc voltages will be recorded on an oscilloscope during events of interest (arcing).

The customer will receive a digital video copy of the wet arc tracking experiments along with a copy of each of the still photographs taken during the day. Additionally, the customer will receive hardcopy charts of the recorded current and arc voltage during at least one period of arcing activity. A final report of test conditions, calibrations and results (explained with photos) is provided. All wire bundles tested will be the property of the customer.

*Testing parameters can be changed or specified by the customer based upon their specific requirements.
