    80 kVA Isolation Transformer Application Areas
    isolation transformer application areaTips: Application of burglar alarm in transformer
    Since outdoor transformer is often stolen, the product such as transformer burglar alarm that can effectively protect the outdoor transformers and solve the problem that power workers deal for many years. Burglar alarm device is installed next to transformer or on the telegraph pole. Once a front-end processor detects disconnection and power failure, it will sent GSM message to the four alarm personnel and alarm information to monitoring center, at the same time it will trigger the voice alarm of on-site loudspeaker. The transformer that sends out the alarm information and the actual location of faulty line are clearly displayed on the electronic map of monitoring center. After receiving the alarm, the police on duty will immediately be sent to the scene to have a check and deal with the related problem. In addition to disconnection and warning, the machine can access to the alarm amount of vibration, infrared ray, wire wrapping and others for the purpose of protecting the transformer safety.

    Need more detail of ATO isolation transformer? Here is a good explanation about it in this video. To test the accuracy of the transformer voltage, we take a 3000 VA single phase 220V iuput to 110V output isolation transformer as an example.
