   • Turn on the transformer and monitor operating parameters such as voltage, current, and temperature.
   • Perform periodic checks to ensure that the transformer is working properly.

6. Matching accessories

• Monitoring Devices: Temperature sensors, load indicators and warning systems.
• Additional Cooling Systems: Fans or water cooling systems for particularly hot environments.
• Protective Devices: Circuit breakers and fuses to protect the transformer from overloads and short circuits.

7. Mathematical formulas

• Apparent Power: S=P2+Q2S = \sqrt{P^2 + Q^2} $$S$$ $$=$$ P 2 + Q 2 ​Where PP $P$ is the active power and QQ $Q$ is the reactive power.
• Efficiency: Efficiency = Output Power Input Power × 100% \text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} \times 100 \% $$\text{Efficiency}$$ $$=$$ Input Power Output Power ​× $$100\%$$
• Core Losses: Calculated by eddy current analysis and hysteresis losses.

8. Materials He Can Work with

• Resistive Loads: For example, equipment that requires continuous power.
• Inductive Loads: Electric motors and other devices that involve variable current flows.
• Capacitive Loads: It can also handle capacitive loads, but it is important to consider the technical specifications to avoid instability.
