Overview
EN 2591-704:2001 defines a standardized test method for measuring the turns ratio of a transformer used in a coupler in aerospace electrical assemblies. The procedure also allows verification of the input and output voltage phase relationship. This part is intended to be used together with EN 2591-100 (General test methods) and is aimed at ensuring repeatable, verifiable measurements for aerospace manufacturers and test laboratories.
Key Topics
- Purpose: Measure the transformer turns ratio and verify that input and output voltages are in phase.
- Test setup: A signal generator feeds the coupler under test and an oscilloscope measures the input and output voltages. The reference connection is described as: signal generator → coupler → oscilloscope.
- Test signal: The applied test waveform V1 is sinusoidal with a frequency of 250 kHz and an amplitude of 10 V peak-to-peak (Vpp).
- Calculation: The turns ratio N is calculated from measured voltages. In the standard notation, N = V2 / V1, where V1 is the applied input and V2 is the measured output on the transformer.
- Phase requirement: Voltages V1 and V2 shall be in phase; phase verification is part of the acceptance criteria.
- Specification compliance: The measured turns ratio N shall comply with the value specified in the product’s technical specification.
Applications
This test method is directly applicable to:
- Aerospace electrical and electronic equipment manufacturers validating transformer performance in couplers.
- Quality assurance and incoming inspection for components used in aircraft and spacecraft harnesses.
- Test laboratories performing conformity tests to CEN/AECMA aerospace series requirements.
Practical benefits include consistent measurement procedures across suppliers, clear pass/fail criteria for turns ratio and phase, and simplified integration with general test methods defined in EN 2591-100.
Related Standards
- EN 2591-100 - Aerospace series - Elements of electrical and optical connection - Test methods - Part 100: General. This part provides the general test rules and should be used with EN 2591-704:2001.
Practical notes
- Ensure the test temperature and the nominal value of N are stated where required by the technical specification.
- Use calibrated signal generation and oscilloscope equipment to maintain traceability.
- Record both amplitude and phase data to demonstrate compliance.
This concise, repeatable method supports reliable verification of transformer turns ratio and phase in aerospace couplers, helping manufacturers meet standardized quality and interoperability requirements.
