- Measurement of Power Losses at AC Magnetization
- Magnetic measurements represent relatively difficult area of the electrical engineering. Classical measurements have been done for the closed specimens but the modern AC measurement should be realized for open steel sheets and strips. The total error of any magnetic measurement depends on the exciting field error, the error of the...
