Adiradh offers advanced solutions for reliable breakdown voltage testing of insulating oils used in power equipment. Moreover, these systems support routine oil quality assessment to verify insulation performance. Therefore, engineers can evaluate dielectric strength before commissioning and during maintenance activities. In addition, the test sets provide a controlled voltage rise, which ensures consistent and repeatable results. Also, the design supports both laboratory and on-site testing requirements. Furthermore, automated test functions reduce operator dependency and improve measurement consistency. However, operation remains straightforward, which shortens overall test cycles. Consequently, testing throughput increases without affecting accuracy. As a result, oil condition trends can be monitored effectively over time. Thus, preventive maintenance decisions become more data driven. Moreover, compliance with standard oil testing practices is maintained. Finally, the OTS PB and OTS AF series deliver dependable measurements for utilities, service providers, and testing laboratories involved in insulating oil diagnostics.

Insulating Oil Test Sets OTS PB and OTS AF series are designed to measure dielectric breakdown voltage of transformer and insulating oils. Moreover, the series supports standardized test procedures with precise voltage control. Therefore, oil samples can be evaluated under repeatable conditions. In addition, the systems include safety interlocks and automatic shutdown for secure operation. Also, both series offer stable performance across multiple test cycles. Furthermore, clear displays present breakdown values and test status. However, the footprint remains compact for easy installation. Consequently, the equipment suits routine testing programs. As a result, oil acceptance testing and in-service monitoring become efficient. Thus, maintenance teams can assess oil quality quickly. Finally, the overview confirms that OTS PB and OTS AF series are practical tools for dielectric strength evaluation of insulating oils.

Insulating Oil Test Sets OTS PB and OTS AF series are AC high-voltage test systems used for breakdown voltage determination. Moreover, they apply a uniform electric field across standardized oil test cells. Therefore, dielectric failure points are accurately detected. In addition, the systems incorporate precision voltage regulation, electrode gap control, and microprocessor-based control units. Also, automatic test sequences support IEC and IEEE oil testing methods. Furthermore, internal measurement circuits record breakdown voltage values with high resolution. However, safety circuits isolate high voltage during faults. Consequently, operator protection is ensured. As a result, the test sets provide consistent and repeatable diagnostic data. Thus, moisture content, contamination, and aging effects in oil can be identified. Finally, the product architecture supports long-term reliability in laboratory and field environments.
The Insulating Oil Test Sets OTS PB and OTS AF series use controlled AC voltage ramp technology. Moreover, the voltage rise rate is regulated to meet standard test requirements. Therefore, breakdown detection remains accurate and consistent. In addition, digital control improves test repeatability. Also, integrated safety interlocks enhance operational security. Furthermore, automatic oil testing sequences reduce manual intervention. However, data presentation remains clear and simple. Consequently, results are easy to interpret. As a result, maintenance planning becomes more effective. Thus, oil replacement or treatment decisions are supported by objective data. Finally, the technology enables reliable trending of oil dielectric strength over time.
