Transformer Oil Breakdown Voltage Tester

Oil Breakdown Voltage Tester

 

OLT-series Portable Automatic Oil Breakdown Voltage Testers also referred to as Oil BDV testers offered in association with  Kharkov Energo Pribor, Europe with its offices and manufacturing at U.K and Ukraine are used for determining the dielectric strength of mineral and synthetic insulating oils in a transformer.

 

Why Oil BDV Test?

In a transformer- the oils act as an insulation as well as coolant for the transformer core/ windings. Over time, there are contaminations/sludge caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature making it unfit for this purpose. Breakdown Voltage is measured by testing a sample of this oil to observe at what voltage, sparking straits between two electrodes emerged in the oil, separated by specific gap. Low value of BDV indicates presence of moisture content and conducting substances in the oil. Through Breakdown voltage test, transformers' life can be substantially increased as well as identifying any deterioration trend, thus delaying new investment of replacement transformer assets.

 

Stanlay Oil BDV Testers

 

Stanlay BDV Tester for transformer oilmeasure the oil breakdown voltage (BDV) in a fully automatic mode and feature a built-in printer for printing out test results- for on-site testing. Stanlay has two variants- OLT 80 (with up to 80 kV RMS AC output) and OLT 100 (with up to 100 kV RMS  AC output) . Fast high voltage switch-off time makes it possible to carry out test of dielectric liquids, which are easily destroyed under such influences.

 

Transformer oil testing is carried out automatically based on pre-fed IEC, ASTM OR ANY other standards chosen by the operator. Stanlay Oil Testing Machines are also equipped with the means of mixing and measuring the temperature of the oil sample, which ensures compliance with the requirements of most of the national and international oil testing standards. The proprietary software also allows to create custom user standards with a high degree of flexibility. OLT Oil Breakdown testers provide high accuracy and stability of the obtained breakdown voltage values and feature a comprehensive operator protection during high-voltage tests.

 

They come with a test vessel (IEC 60156– basic configuration) with VDE 0370 mushroom-shape electrodes. A gap between electrodes is easily regulated with a use of pass-no pass gauge, which comes in pack. To simplify the procedure of calibration and adjustment of the OLT-series Oil Breakdown testers, special C-series reference voltage measurement cell with a bright LED display are offered. The cells C-80 and C-100 Oil BDV Calibrators have an infrared port for wireless connection with a PC, which allows the operator to remain at a safe distance from the high voltage source while using the proprietary KEP Suite software for quick and efficient adjustment of the cell itself.

 

Safety:

Designed in accordance with IEC 61010 safety requirements. Meets light industrial IEC 61326-1 Class B, CISPR 16-1, CISPR 16-2 and CISPR 22.

 

The Transformer oil BDV tester is a very crucial & routine test that can help in reducing transformer replacement costs and losses- as well as identify deterioration trends for timely action.
