M4000 Product Options

The M4000 comes with different options used to create the ultimate diagnostic testing equipment. Each test equipment can be configured to meet your needs.

TTR Capacitor

Turns Ratio Testing to detect shorted turns or winding damage
With the addition of the TTR Capacitor, the M4100 can measure the turns ratio of power transformers at potentials up to 10 kV.

M4110 Leakage Reactance Module

Detect Winding Movement
Use the M4110 Leakage Reactance Module to perform short circuit impedance tests on transformers – a vital tool in diagnosing winding deformation.

M4120 External Reference Module

Test at potentials greater than 12kV
The M4120 External Reference Module allows the measurement circuit of the M4100 to be used with an external power supply and reference capacitor to test at voltages greater than 12 kV.

Type C Resonating Inductor

Test large specimens
The Type C Resonating Inductor is an adjustable reactor designed to extend the charging current range of the M4100 to test larger apparatus.

M4151 Field Calibration Reference Module

Ensure valid results
The M4151 Field Calibration Reference Module provides calibration verification of the M4100 in the field.

Temperature/Humidity Probe

Record environmental influences
The optional Temperature/Humidity Probe automatically measures temperature and humidity, providing critical information for the diagnostic evaluation.

Safety Strobe Light

The Safety Strobe Light flashes while the M4000 tests are in progress, providing a visual warning of high voltage presence.

M4300 Transport

Portability
The M4300 Transport cart ensures smooth easy travel over all terrain. High-density plastic molded transport cases are specifically designed for shipment of the M4100 or M4300 by air freight or truck over rough terrain.

Doble Test Assistant (DTA)® Software

Provides enhanced expert system capabilities. It is made up of two components: Field and Office. DTA Field supports data retrieval with apparatus specific test forms, standardized test procedures and test result analysis. DTA Office incorporates the results into a relational database.

M4000

Power Factor Testing to confirm insulation integrity and quality.

The M4000 diagnostic system evaluates the integrity of high voltage substation apparatus by measuring the power factor/tangent delta along with a number of other essential values. It also measures the capacitance to evaluate physical changes to the apparatus.

M4000 Product Software

All M4100s come with standard M4000 software to simplify the management of test results. It also offers a range of diagnostic tools and comprehensive self-diagnostic capability.
