Doble M4100 Power Analysis is Smart, Automated Test Equipment

Doble-M4100The Doble M4100 Power Analysis, together with the DTA Expert System Software, represent the new generation of smart, automated test equipment used to determine the condition of high voltage substation apparatus.

The Doble M4100 Power Analysis eliminates interference problems

The M4100 Power Analysis uses a patented technique called Line Frequency Modulation™, in which the measurement is made at a frequency above and below the system frequency. This method eliminates the effect of varying electrostatic interference. As a result, you get highly accurate and repeatable measurements, and even a small change in the measurement can be used reliably for diagnostic purposes.

Generates its own clean signal for the most reliable results

The accuracy of test results is directly related to the quality of the test signal. While most test instruments use available power lines or portable generators to generate the output test signal, the M4100 uses an internal waveform generator to produce its own precise sine wave test signal. As a result, the M4100 produces reliable results and stable readings – thus the quality of the power source is not an issue.
