Major Tech 10kV Diagnostic Insulation Tester – MT577

Conduct ultra-high voltage insulation diagnostics and preventative asset maintenance with the Major Tech 10kV Diagnostic Insulation Tester (MT577). Designed for high-voltage engineers, power distribution specialists, and electrical contractors, this heavy-duty instrument delivers variable insulation test voltages up to 10kV in 50V increments and measures insulation resistance up to 35TΩ. Featuring advanced Polarization Index (PI) and Dielectric Absorption Ratio (DAR) diagnostic modes, internal memory, and a rugged field case, it provides comprehensive testing for high-voltage transformers, switchgear, motors, and transmission cables.

Key Features:

• Extended High-Voltage Output: Configurable insulation test voltages from 250V to 10kV in precise 50V steps.

• Ultra-High Resistance Measurement: Tests insulation resistance up to 35TΩ across auto-ranging insulation scales.

• Automated Diagnostic Ratios: Provides built-in calculation and indication of Dielectric Absorption Ratio (DAR) and Polarization Index (PI).

• High Short-Circuit Current: Features up to 6mA short-circuit current for quick capacitive charging on long lines and heavy apparatus.

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

• Onboard Memory & Auto-Hold: Internal memory stores up to 500 measurement results for display recall, complemented by Auto Hold to lock readings on-screen.

• Programmable Timer & Alarms: Includes an adjustable test duration timer (1 to 30 minutes) and configurable high/low threshold alarms.

Detailed Description:

The Major Tech MT577 is engineered for high-precision diagnostic testing of extra-high voltage electrical infrastructure. Built into a durable, impact-resistant protective case with lid-mounted step-by-step instructions, it is purpose-made for harsh industrial and outdoor field conditions.

Its large 4-bit backlit digital display provides high visibility in dark or shaded switchrooms, while microprocessor control ensures stable accuracy across extreme resistance ranges. With an automatic power-off feature and comprehensive safety testing modes, the MT577 simplifies utility-grade insulation assessments.
