VINDAION ST3128 High-Voltage Digital Insulation Resistance Tester

Industrial-Grade 10KV Megohmmeter with Data Logging & PC Connectivity

I. Product Overview

The SMART SENSOR ST3128 is a high-performance, digital insulation resistance tester designed for demanding industrial and power system applications. Unlike traditional hand-cranked "shake tables," this device offers precise, stable, and automated high-voltage testing up to 10KV. It features a rugged, protective casing with a large, backlit LCD display that clearly presents measurement data, test voltage, and battery status. The ST3128 is engineered for safety and efficiency, incorporating automatic discharge, overload protection, and intelligent data management, making it the ideal choice for maintenance in power grids, transformers, cables, and heavy machinery.

II. Key Features & Highlights

Ultra-Wide Voltage Range
- Supports six selectable test voltages: 250V, 500V, 1000V, 2.5KV, 5KV, and 10KV. This versatility allows for testing a wide variety of equipment, from low-voltage control circuits to high-voltage transmission lines.
Advanced Measurement & Analysis
- Insulation Resistance (IR): Measures up to 3000GΩ with high precision.
- Polarization Index (PI) & Dielectric Absorption Ratio (DAR): Automatically calculates these critical values to assess the quality and moisture content of insulation materials over time.
Intelligent Data Management
- Data Storage: Stores up to 500 sets of measurement data with automatic numbering.
- PC Connectivity: Equipped with a USB interface and dedicated software for real-time monitoring, data upload, and report generation on a computer.
Superior Safety & Protection
- Automatic Discharge: Automatically discharges residual voltage from the tested object after measurement, protecting the operator.
- Overload & Alarm Protection: Features overload protection and a customizable alarm that triggers with visual and audible alerts if values exceed set thresholds.
User-Centric Design
- Large Backlit LCD: A 4-digit, 108mm x 65mm display with adjustable gray/white backlight ensures readability in bright sunlight or dark environments.
- Rechargeable Power: Powered by a built-in 12.6V rechargeable lithium battery, eliminating the need for disposable cells.

III. Applications

The ST3128 is widely used across various industries for preventive maintenance and fault diagnosis:

Power Industry: Testing transformers, switchgear, and transmission lines.
Industrial Manufacturing: Insulation testing for motors, generators, and control panels.
Infrastructure: Verifying cable insulation in railways, mining, and construction.
Energy Sector: Maintenance of wind turbines, solar farms, and oilfield equipment.
Facility Management: Routine checks on building electrical systems and charging stations.
