The new Hioki VT1005 high voltage divider accepts input voltages up to 5kVrms /4MHz for accurate power measurements
In order to meet the continuous need for more electrical power, there is a trend to introduce higher system voltages in a wide range of applications. One particular application is the accurate efficiency measurement of railways, trucks and busses that are operating at voltages higher than 1000V. Accurate power loss measurement of inductive components used in HV power electronics is another interesting application.
Engineers prefer to measure the loss in these devices under real-life conditions and the very low power factor of these measurements requires a phase error compensation to achieve accurate measurements. This can be discovered with the Hioki High Voltage Divider.
SiC semiconductors are increasingly used for high-voltage applications with switching frequencies of 50kHz or higher. The VT1005 High Voltage Divider is the only solution on the market today that is designed to provide accurate results even at these high switching frequencies.
