Overview:

Perform high-voltage insulation integrity analysis and preventative maintenance with the Major Tech 5kV Diagnostic Insulation Tester (MT574). Designed for high-voltage electricians, substation technicians, and industrial plant engineers, this heavy-duty instrument delivers test voltages up to 5000V in 50V increments. Featuring diagnostic testing modes including Polarization Index (PI) and Dielectric Absorption Ratio (DAR), onboard memory, and a rugged protective casing, it ensures thorough evaluations of motors, generators, transformers, and high-voltage cabling.

Key Features:

  • Variable High-Voltage Output: Adjust insulation test voltages from 100V to 5000V in precise 50V steps.

  • Diagnostic Index Testing: Automated calculation and indication of Dielectric Absorption Ratio (DAR) and Polarization Index (PI) ratios.

  • High-Short Circuit Current: Delivers a short-circuit current of up to 6mA for fast capacitive charging during high-voltage tests.

  • Voltage Measurement Capabilities: Measures AC voltage up to 750V and DC voltage up to 1000V.

  • Onboard Memory & Auto-Hold: Internal storage holds up to 500 measurement results for later recall, supported by Auto Hold to freeze readings automatically.

  • Programmable Timer & Alarms: Features adjustable test duration settings from 1 minute to 30 minutes, along with customizable high/low alarm limits.

Detailed Description:

The Major Tech MT574 provides micro-processor-controlled accuracy for high-voltage insulation diagnostics. Housed in a heavy-duty, protective case with quick setup instructions printed directly inside the lid, it is built to withstand harsh field environments.

Its large 4-bit backlit digital LCD offers clear readouts under low-light site conditions, while auto-ranging across all insulation test bands simplifies operational steps for field engineers.
