A NEW addition to the comprehensive range of Megger OTD Oil Test Sets, the Megger OTD Oil Tester measures Tan Delta, resistivity and relative permittivity of insulating oils. The Megger Oil Tan Delta unit is a fully automated tester and comes loaded with a set of international test standards:
- IEC 60247:2004
- IEC 61620:1998
- ASTM D924-08
- ASTM D1169:2002
- BS 5737:1979
- JIS C2101:1999
- VDE 0380-2:2005_01
- IS 6262:1971
- IS 6103:1971
As well as the international set of standards, the Megger OTD supports up to six customer configurable test sequences. Productivity in the laboratory is maximised, with the focus on reducing the test cycle time by fan cooling and inductive heating, together with an oil flow and drain facility, negating the need to move the oil vessel. The Megger Oil Tan Delta unit has a 12 key alpha-numeric keypad to facilitate entry of test ID, filenames, notes, etc.
Test results are identified by a test ID and are time and date stamped. Megger’s asset and data management software, PowerDB Lite, included at no extra cost, provides a tool for downloading results via the USB interface, while an internal printer provides hard copy results. Ink based printout ensures durability at all temperatures.
User safety is paramount and the Megger OTD Oil Tester has been designed with independent, dual redundant high voltage cut-off circuitry to ensure safety. During a test, press any button on the keypad to remove the high voltage immediately and abort the test. The transparent lid provides ample visibility within the chamber.
Oil Tan Delta Applications:
Monitoring and maintenance of oil quality is essential to ensure the reliable operation of oil filled electrical equipment. Codes of practice have been established in many countries that include tests for Tan Delta, Relative Permittivity and Resistivity. The Megger OTD identifies oil condition quickly, detecting the presence of moisture and other contaminants in insulating oil samples.
- New oil reception - quality test
- Regeneration of oil - quality test
- Monitoring and maintenance of oil quality in oil filled electrical equipment
- Transformers
- Switch Gear
- HV Cables
❓ Frequently Asked Questions (FAQ)
Q1. What does the Megger OTD Oil Tester measure?
A. The Megger OTD Oil Tester measures Tan Delta, resistivity and relative permittivity of insulating oils to indicate oil quality. It is one of the most reliable ways to assess the presence of moisture and contamination.
Q2. Why is Tan Delta measurement important?
A. Using the Megger Oil Tan Delta test highlights changes in oil quality that can indicate the presence of moisture, ageing, or other deterioration. This helps prevent failures in transformers, switchgear, and HV cables.
Q3. What temperature is measured during testing?
A. The Megger OTD accurately records the temperature measured within the oil test cell, heating samples up to 110°C with uniformity across the oil to deliver precise results.
Q4. How does the oil flow system work?
A. The Megger OTD Oil Tester includes efficient oil fill and an integrated automated drain facility, ensuring safe oil flow management during testing and reducing handling requirements.
