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.

We can also help with these: Automated setup eliminates errors. Coble sets the standard for accuracy, reliable test results, and intelligent diagnostics for customers worldwide. It also measures capacitance, to evaluate physical changes to the apparatus. Generates its own clean test signal for the most reliable and repeatable results.

Unlike other test instruments, the M eliminates the need to balance the bridge, automatically making measurements for you.

Even a small change in a measurement becomes a reliable diagnostic indicator. Advanced digital technology takes accuracy to new levels.

This produces reliable results and stable readings. 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.

The M has the power to test a wide range of apparatus, making it highly versatile. Rugged construction provides the accuracy of a laboratory instrument with the ability to withstand harsh field conditions.

While most test instruments use available power lines or portable generators to generate the output test signal, the M uses an internal waveform generator to create its own precise sine wave. Electrical Safety Onsite Testi Built-in test set diagnostics provide m410 on instrument status.

The internal measurement circuitry is fully digital. With a maximum output of mA at 10 kV, the M offers high charging current, allowing you to run single-phase exciting current tests at higher voltages, increasing the turn-to-turn soble. The M allows you to perform a variety of diagnostic tests: Dielectric testing for our electrical testing laboratory. Provides the highest power to better replicate in-service conditions.

If you need more current than mA for large apparatus, the Type C Resonator option extends the range. The Liquid-Insulation Cell Oil Cellalso supplied with the M, can be used in the field for a quick accuracy check.

The M is the leading instrument for evaluating the condition of high-voltage power apparatus. Cleaning, dielectric testing, drying, visual inspections, stamping, packing, and documentation is all The quality of the power source is not an issue. The accuracy of test results m410 directly related to the quality of the test signal.
