Overview

The DMI 553 is a portable, highly integrated, versatile digital  measuring instrument for AC and DC in high voltage laboratories according IEC 61083-3:2020. High voltage measurements are done by connecting a specialized voltmeter (like the DMI 553) to the secondary unit of a voltage divider or to a current to voltage transducer (like a shunt). The DMI 553 has been developed to measure, record and visualize events during dielectric and breakdown tests in high voltage applications according to IEC 61083-3:2020. Measured values are shown as large digits on the computer screen using Haefely CaMS software. In addition, for pass/fail criteria during dielectric tests, Peak by √2 voltage is recorded & last value before breakdown is shown. Graphical indications as scope function, FFT, datalogger or flash detetion are included. To facilitate easy comprehension, voltage divider ratio or shunt conversion factor (A/V) can be incorporated in the calculation to display parameters directly in kV or A. Fiber optic connection guarantees galvanic isolation between the operator and high voltage test lab, increasing safety. The DMI can generate reports based on templates which can be printed or saved as PDF. Snapshots of the display or charts can be easily included in the reports.
