Transformer can transform the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.
A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed in parallel
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
