DOBLE M4100 PDF

Photo: Doble Most failures of electrical power equipment are the result of a breakdown in the insulation system. To keep failures at a minimum, periodic maintenance testing of the insulation is recommended to indicate whether it is deteriorating, and how fast. Power factor tests are used to measure dielectric losses, which relate to the wetness, dryness or deterioration of electrical insulation. Power factor is defined as the cosine of the phase angle between voltage and current. Measuring insulation power factor is achieved by calculating the ratio of the capacitive or "charging" current measured in voltamperes to resistive or "leakage" current measured in watts.

This produces reliable results and stable readings. 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. 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 stress.

Cleaning, dielectric testing, drying, visual inspections, stamping, packing, and documentation is all Dielectric testing for our electrical testing laboratory. The M allows you to perform a variety of diagnostic tests: Rugged construction provides the accuracy of a laboratory instrument with the ability to withstand harsh field conditions.

Provides the highest power to better dble in-service conditions. The M has the power to test a wide range of apparatus, making it highly versatile. Built-in test set diagnostics provide information on instrument status. The M instrument comes with M software to simplify the management of test results. Automated setup eliminates errors.

Doble — M The M was engineered soble the ground up to overcome the common problems that plague other test instruments. The result is highly accurate and repeatable measurements. The quality of the power source is not an issue. Advanced digital technology takes accuracy to new levels. The accuracy of test results is directly related to the quality of the test signal.

M software makes testing easy, fast, and smart. Electrical Safety Onsite Testi Records are presented in a format that is easy to read, save, and print. It sets the standard for accuracy, reliable test results, and intelligent diagnostics for customers worldwide. The M is the leading instrument for evaluating the condition of high-voltage power apparatus.

The M also uses n patented technique called Line Frequency Modulation, in which measurements are made at a frequency above and below the system frequency, to eliminate the effect of electrostatic interference.

Get a quick quote: If you need more current than mA for large apparatus, the Type C Resonator option extends the range. Daily, Weekly doblr Monthly rates are available on select items. Generates its own clean test signal for the most reliable and repeatable results. New PurchaseRental. One stop for your electrical safety equipment needs, cleaning, and electrical testing services. While roble 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 glove testing is available at JM Test Systems. Doble M Power Factor tester. It also offers a range of built-in self-diagnostic tools.

It also measures capacitance, to evaluate physical changes to the apparatus. Related Posts
