Oil Dielectric Tester

Introduction

Oil dielectric tester is a specialized instrument used in the electrical industry to evaluate the dielectric strength of insulating oils. This crucial parameter indicates the oil's ability to withstand electrical stress and prevent breakdown, ensuring the reliability of transformers and other high-voltage equipment. The tester typically operates by immersing electrodes in the oil sample and applying a voltage until electrical breakdown occurs. Regular testing with the Oil Dielectric Tester is essential for preventive maintenance, helping identify potential issues before they lead to equipment failure. This instrument is a valuable tool for power utilities, substations, and industrial facilities, contributing to the overall safety and performance of electrical systems by ensuring the insulating oils maintain the required dielectric properties over time.

FAQ

What is the Oil Dielectric Tester mainly used for?

The Oil Dielectric Tester is used for a defined laboratory measurement, preparation or processing task. It supports analytical, quality-control, research, clinical or industrial work where consistent, repeatable results are required.

Which standards and regulations apply to the Oil Dielectric Tester?

The instrument is designed with reference to IEC 61010 electrical safety, the applicable international standard for the measurement or process and relevant GB/T standards. Procedures should follow the relevant method. Compliance documentation can be provided on request.

What does the warranty cover?

We provide a 12-month limited warranty on the instrument and its key working parts. Consumables, accessories and parts subject to normal wear are excluded, as is damage caused by incorrect operation or maintenance. An extended service plan is available on request.

Will staff need special training?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Oil Dielectric Tester be calibrated?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are consumables and spare parts easy to obtain?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Can it be adapted to our requirements?

Customisation is supported for many installations, including tailored parameters, connections and accessories. Our team reviews the requirement and confirms feasibility and lead time in advance. We avoid committing to options that cannot be delivered reliably.

How is the Oil Dielectric Tester commissioned?

The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.

What should be avoided when using the Oil Dielectric Tester?

Do not use the instrument outside its rated range or intended samples, skip calibration or ignore safety and maintenance instructions. Follow the operating manual and laboratory safety rules.
