MEGGER- MIT30 | 30kV HIGH VOLTAGE TESTER
 
The Megger MIT30 is a portable 30-kV high-voltage insulation tester (dielectric test set) engineered to satisfy the demand for high-voltage, high-accuracy, and low-current applications. Developed for testing ungrounded samples, it delivers a continuously variable test voltage from 0 to 30 kV DC while measuring low leakage currents down to high-precision nanovolt/nanoamp resolutions. It is ideal for use in electrical power utilities, manufacturing QA/QC lines, aerospace, and defense industries to verify the structural integrity of critical insulation materials.
 
Features & Benefits
 
Continuously variable test voltage ranging from 0 to 30 kV DC with an output accuracy of +/- 1.5% (full scale)
High-precision current measurement supporting up to 330 uA test current with high resolution.
User-selectable current trip points (0 to 360 uA) to protect test pieces from excessive damage during a breakdown.
Built-in adjustable ionization (audible) indicator to detect partial electrical discharges during testing.
Fail-safe gravitational grounding switch and zero-start interlock safety features.
The current guard circuit prevents external surface leakage interference for enhanced measurement accuracy.
Rugged, lightweight, and compact field-proven enclosure featuring an air transport pressure relief valve.
 
Use cases / Application
 
Acceptance and routine maintenance testing of electrical plant equipment (switchgear, busbars, and capacitors).
Proof testing and step-voltage diagnostics to predict insulation failure before complete breakdown.
Quality assurance (QA/QC) production tests by power equipment and plant manufacturers.
Testing of vacuum interrupters and specialized safety gear like rubber gloves.
High-voltage insulation evaluations within aerospace and defense maintenance programs.
