1. Frequência de operação A perda do núcleo do transformador tem uma ótima relação com a frequência, por isso deve ser projetado e utilizado de acordo com a frequência de uso. Essa frequência é chamada de frequência de operação.
2. Rated power Under the specified frequency and voltage, the transformador can work for a long time without exceeding the output power of the specified temperature rise.
3. Rated voltage refers to the voltage allowed to be applied to the coil of the transformador, which shall not be greater than the specified value during operation.
4. Voltage ratio refers to the ratio of the primary voltage to the secondary voltage of the transformador, and there is a difference between the no-load voltage ratio and the load voltage ratio.
5. No-load current When the secondary of the transformador is open, there is still a certain current in the primary, and this part of the current is called the no-load current. The no-load current consists of the magnetizing current (which produces the magnetic flux) and the iron loss current (caused by core losses). For a 50Hz power transformador, the no-load current is essentially equal to the magnetizing current.
6. No-load loss refers to the power loss measured at the primary when the secondary of the transformador is open. The main loss is the iron core loss, followed by the loss (copper loss) generated by the no-load current on the copper resistance of the primary coil, and this part of the loss is very small.
7. Eficiência refere-se à porcentagem da relação entre a potência secundária P2 e a potência primária P1. Geralmente, quanto maior a rated power of the transformador, maior a eficiência.
8. Insulation resistance Indicates the insulation performance between the coils of the transformador and between the coils and the iron core. The level of insulation resistance is related to the performance, temperature and humidity of the insulating material used.
