Working frequency
The core loss of high-voltage transformer has a great relationship with frequency, so it should be designed and used according to the frequency of use. This frequency is called the operating frequency.
Rated power
Under the specified frequency and voltage, the high-voltage package can work for a long time without exceeding the output power of the specified temperature rise.
Rated voltage
Refers to the allowable voltage applied to the coil of the high-voltage package, which shall not be greater than the specified value during operation.
Voltage ratio
Refers to the ratio of the primary voltage to the secondary voltage of the high-voltage package. There is a difference between the no-load voltage ratio and the load voltage ratio.
No-load current
When the secondary of the high-voltage package transformer is open, there is still a certain current in the primary, and this part of the current is called the no-load current. No-load current is composed of magnetizing current (produced magnetic flux) and iron loss current (caused by iron core loss). For a 50Hz power transformer, the no-load current is basically equal to the magnetizing current.
Load loss
Refers to the power loss measured on the primary when the secondary of the high-voltage package transformer is open. The main loss is the core loss, followed by the loss (copper loss) caused by the no-load current on the copper resistance of the primary coil. This part of the loss is very small.
