Insulation Analysis

Doble's Insulation Analysis equipment offers the world's most advanced testing for power apparatus. The M4100 is the leading instrument for evaluating the condition of high-voltage power apparatus. It sets the standard for accuracy, reliable test results, and intelligent diagnostics for customers worldwide.

The M4100, together with DTA Expert System software, represent the new generation of smart, automated test equipment used to determine the condition of high-voltage substation apparatus.

M4100

The M4100 Insulation Analyzer 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. The M4100 provides accurate evaluations even under conditions of high electrostatic and electromagnetic interference.

DTA Software

Doble Test Assistant (DTA) software is a comprehensive software package to enhance productivity and enable maintenance engineers to make informed decisions on apparatus condition in the field. DTA uses a Doble-developed expert system based on decades of analysis of field test results. DTA software works with the M4100 instrument as automated test equipment to determine the condition of high-voltage substation apparatus.

M2H-MCM

The M2H-MCM (M-series Control & Measurement) Insulation Analyzer brings automatic power factor measurement techniques to M2H users in an easy-to-use instrument package. The MCM works with the M2H Transformer unit to provide automated test capability. Plug the intercase lead of the M2H Transformer into the MCM, and all the measurements and calculations are performed automatically. The M2H-MCM provides a graphical user interface, automated measurements, and data management, producing stable test results and fast test times
