Megger OTS PB and OTS AF Insulating Oil Test Sets

Buy Megger OTS PB and OTS AF insulating oil test sets in the UAE from MME, an authorized Megger representative. Browse our Megger range and related circuit breaker / high-voltage test instruments.

Overview

The Megger OTS PB and OTS AF ranges are automatic oil breakdown-voltage test sets for mineral, ester and silicone insulating liquids — a key indicator of oil condition in transformers and other oil-filled equipment. Both ranges automatically raise the test voltage at a standard rate, detect breakdown, stir and repeat the sequence, and calculate the average, giving fast, repeatable results to international standards.

The OTS PB models are lightweight and can run on rechargeable battery or mains, making them ideal for on-site testing at up to 60 kV or 80 kV. The OTS AF models are fully automatic, mains-powered laboratory instruments with a larger chamber and alphanumeric keypad, available up to 100 kV. All models share a colour display, internal printer, USB transfer and bundled PowerDB Lite software.

Key Features

Choose PB for portable site work or AF for high-throughput laboratory testing:

• Automatic dielectric breakdown-voltage testing of insulating oils (mineral, ester, silicone)
• OTS PB — portable, battery or mains: OTS60PB (60 kV) / OTS80PB (80 kV)
• OTS AF — fully automatic lab: OTS60AF / OTS80AF / OTS100AF (up to 100 kV)
• Selectable rise rates 0.5 / 2.0 / 3 kV/s (custom up to 10 kV/s), accuracy better than 5%
• Built-in standards: IEC 60156, ASTM D877/D1816, BS EN 60156, VDE, GB/T, plus custom tests
• 400 ml test vessel (150 ml option); spherical, mushroom and cylindrical electrodes
• 3.5 in. colour display, internal printer, USB and PowerDB Lite software; AF models support barcode IDs

Applications

Typical oil-quality and asset-condition uses include:

• Dielectric strength testing of new and in-service insulating oils
• On-site oil testing with portable PB models across UAE substations and plants
• Laboratory oil-quality testing and LIMS-friendly workflows with AF models
• Condition monitoring of transformers and other oil-filled HV equipment
