FAQ's of Metravi 90-MOTS Motorised Oil Test Set:
Q: How is the Metravi 90-MOTS Motorised Oil Test Set used for dielectric strength testing?
A: The Metravi 90-MOTS is used by placing a 400 ml oil sample in the transparent polycarbonate cup, adjusting the electrode gap between 1 and 4 mm, and selecting the desired control mode-either automatic or manual. The device gradually increases voltage while monitoring breakdown, providing audio and visual indications at the point of dielectric failure, with results recorded digitally.
Q: What safety features are incorporated to protect users and equipment?
A: This unit includes earth leakage and overload protection systems, a fully enclosed body for safe motorized operation, and a lid lock safety interlock, ensuring tests can only commence when the device is properly secured. These measures prevent accidental exposure and equipment damage during high-voltage testing.
Q: When should calibration be performed on this oil test set?
A: Calibration should be performed periodically according to your laboratory or field testing protocols, or whenever accuracy verification is needed. The unit's calibration is traceable to national standards, supporting reliability and compliance with IEC 60156 / IS:6792.
Q: Where can the Metravi 90-MOTS be operated?
A: This test set is designed for both laboratory and field usage, suited for indoor environments with temperatures from 0 to 40C and humidity up to 90%. Its bench-top mounting and compact dimensions allow flexibility in deployment within Indian testing facilities.
Q: What is the process for adjusting the electrode gap in the oil cup?
A: The electrode gap can be adjusted between 1 to 4 mm using the provided adjustment mechanism. Ensure the oil sample is placed correctly, and adjust the gap as required before initiating the dielectric strength test for accurate and standardized results.
Q: What are the benefits of using this motorised oil test set?
A: Benefits include high-precision dielectric testing up to 60 kV, instant digital readouts, secure and safe operation through multiple protective features, ease of data management via internal memory, and compliance with international standards-making it ideal for consistent oil quality assessment.
Q: How many test records can the internal memory store and how is data accessed?
A: The internal memory of the Metravi 90-MOTS can accommodate up to 100 individual test records. Recorded data is accessible through the front panel controls, streamlining post-test analysis and reporting.
