Doble M Rent and purchase options available at JM Test. The M is the leading instrument for evaluating the condition of high-voltage power. Insulation systems associated with many types of high-voltage power apparatus and devices often consist of a mix of non-homogeneous component parts. The Doble M evaluates the integrity of high-voltage substation apparatus by measuring the power factor/tangent delta along with capacitance to evaluate.

Unlike other test instruments, the M eliminates the need to balance the bridge, automatically making measurements for you. Built-in test set diagnostics provide information on instrument status. It also measures capacitance, to evaluate physical changes to the apparatus. Get a Quick Quote. M software makes testing easy, fast, and smart.

Records are presented in a format that is easy to read, save, and print. Provides the highest power to better replicate in-service conditions. The Liquid-Insulation Cell Oil Cellalso supplied with the M, can be used in the field for a quick accuracy check.

Doble M4100, 4th Gen

The M also uses a patented technique called Line Frequency Modulation, in which measurements are made at a frequency above and below the m41000 frequency, to eliminate the effect of electrostatic interference. Electrical glove testing is available at JM Test Systems.

The M was engineered from the ground up to overcome the common problems that plague other test instruments. With a maximum output of mA at 10 kV, the M400 offers high charging current, allowing you to run single-phase exciting current tests at higher voltages, increasing the turn-to-turn stress.
