Fast testing platform for the isolation transformer

This work shows a program created in a Labview environment to verify the correct functioning and regulatory compliance of isolation transformers and isolation transformers for medical use. The transformer tests will be divided into acceptance tests and type tests. For each type of test, the program will be able to provide information for correct testing and to speed up the test path.The guided test procedure will accompany the author up to the automatic printing of the test reports. Finally, considerations will be made on which tests to perform on already installed transformers that require recertification.

Newly Developed Compact Isolation Transformers for Signaling Networks

This paper describes the specifications of newly developed compact isolation transformers for signaling networks such as telecommunication installations and information installations. These networks can use isolation transformers to mitigate surges occurring on services. It means that isolation transformers are used to eliminate the affect of noise and common mode voltage. Also the isolation transformers provide lightning protection for these networks. As the specifications of conventional isolation transformers are not sufficient, small-sized isolation transformers were developed. The new isolation transformers offer high isolation withstand voltage (50kV, 1.2/50μs) with low insertion loss (0.5dB) in the transmission frequency band of 500Hz to 30 MHz. The weight is only 0.3kg and the size is only 6×6×5cm.
