Oil Tan Delta & Resistivity Test Set

The Motwane MOTR is a compact, microprocessor-based device engineered for precise measurement of dissipation factor (tan δ) and volume resistivity in insulating oils. Compliant with IEC 60247 standards, it features a dual-temperature test cell (27°C and 90°C) and a built-in calibrator for performance verification. The MOTR streamlines oil diagnostics with automated oil drainage, customizable test sequences, onboard data storage and printing, and seamless connectivity via USB and Bluetooth. Integrated with the MOT-WARE cloud platform, it enables real-time data analysis, report customization, and AI-driven insights for predictive maintenance, offering a comprehensive solution for oil testing and asset management.

The OTS measures the dielectric strength of insulating oil and essential detect of its health. Dielectric strength is the maximum electrical stress an oil can withstand before it breaks down and becomes conductive. The OTS provide the information about oil condition such as Contamination Level, Aging and Degradation, and Insulation Integrity.
The BDV test has been designed in compliance with both ASTM and IEC standards, providing international use. The OTS series BDV testers follow to ASTM (D1816-12, D877-19) and IEC 60156 (2018 revision).
The OTS is crucial for transformer reliability because it provides a direct assessment of the health of the insulating oil, which is an essential component for both electrical insulation and cooling. The BDV test, performed by an OTS, is a primary indicator of the oil's condition and serves as a vital tool for preventive maintenance.
A BDV test is a good initial point for assessing insulating oil, Tan Delta and Resistivity testing provide deeper insights into the oil overall quality and degradation.
Measuring volume resistivity of insulating oil is a essential test for assessing its electrical insulating capability and detecting contaminants. Volume resistivity is a fundamental property that measures the oil resistance to leakage current flowing through its body when a DC voltage is applied.
The dissipation factor is a highly sensitive indicator of the dielectric losses in insulating oil. It is directly linked to oil aging and contamination because these factors introduce impurities that increase the oil's conductivity and energy loss.
Determining the exact Tan Delta values that necessitate oil reconditioning or replacement depends on several factors, including the type of oil, whether it's new or in-service, and the operating temperature at which the test is performed.
The MOTR (Motwane Oil Tan Delta & Resistivity Kit) follows compliance with ASTM D924, ASTM D1169, and IEC 60247, and its specific testing procedures and technical requirements are outlined in each standard. There are features that ensure compliance, such as accurate measurement & calibration, a standardized test cell, and precise temperature control.
