About 100KV Motorised Oil Test Set

General Arrangement:

The Set will be consisting of the following:

HT Transformer, Control circuit, Test Cell with electrode, gauge and supply input cable of at least 2 meters length with 3 pin plug. The Set will be in single unit. Instruction manual and Test report will be supplied along with the Set.

HV Transformer:

High Voltage Transformer used in the Test Set will be of cast resin type. The HV winding of the transformer is of graded insulation with center point of HV winding grounded. This testing transformer is specially designed to withstand frequent intermittent sparkover or momentary short circuit conditions under which such testing transformer is supposed to operate.

The Control Circuit well be Consisting of the Following:

Power Mains ON OFF operation is done by means of an ON OFF switch along with MAINS ON lamp indication & Fuse.

HT ON OFF push buttons along with 'HT ON lamp indication.

Lamp to indicate Regulator not at zero

Continuously variable autotransformer of suitable capacity to increase/decrease the output test voltage up to the required voltage level.

INCREASE/DECREASE circuit to control motor operated Voltage Regulator. When high voltage circuit is switched ON the regulator will rotate to increase the output voltage when INCREASE push is pressed ON or decrease the output voltage when DECREASE push is pressed.

Memory device enables the test set meter to show the breakdown voltage by pressing the MEMORY push even after the high voltage circuit is tripped OFF.

Protection and Interlocks:

Zero start interlocking will be provided to ensure that the HV circuit cannot be energised unless the regulating transformer is at zero position or brought back to zero position.

Door interlocking (HV chamber interlocking) will be provided to ensure that the HV circuit cannot be energised unless the transparent cover of the oil cell placement chamber is closed.

Beside main switch and fuse in the input side, one CT and contactor provides a snap acting automatic tripping of HV circuit in case of overload or breakdown of oil sample under test. Quick acting D.C relay to isolate the H.T will be provided.

In case the output voltage crosses the maximum rated value a lamp & a buzzer will indicate over voltage and the increase mode circuit will not function further, even if 'PRESS TO INCREASE push is pressed.

Metering:

96sq. mm. AC moving iron type voltmeter connected to the LT side and scaled in kV. [Digital meter can be provided at extra cost]

Mode of operation of output voltage variation:

Motor driven arrangement of voltage regulator with approx. rate of rise of output voltage 2KV/sec.

Test Set Housing:

All the components and HV Transformer along with Test Vessel will be housed within MS cabinet provided with wheels and handles for easy movement. A transparent cutout with suitable interlocking device will be provided for covering the HT end. The Set cannot be energised unless this HT end is covered. The oil cell is to be placed between the HV terminals.

Test Vessel (Test cup):

The Test Vessel (Oil Cell) is fitted with two brass spheres of diameter between 12.5 to 13mm, placed at a distance of 4mm or 2.5mm. The test vessel is made from non-absorbent insulating material. Gap of the spheres can be adjusted by adjusting one sphere while the other being fixed. Dimensions are generally as per IS 6792:1992. A gauge will be provided along with the cell to adjust the gap.

Flexible and Compliant Design

Featuring an adjustable electrode gap and compliant with IS: 6792 and IEC: 156 standards, this unit adapts to various testing requirements. The transparent test chamber and built-in digital timer (up to 999 seconds) enable clear observation and process flexibility, while automatic discharge and tripping mechanisms guarantee operational reliability.

FAQ's of 100KV Motorised Oil Test Set:

Q: How does the 100KV Motorised Oil Test Set facilitate transformer oil testing?

A: This test set is engineered to verify the dielectric strength of transformer oil by precisely applying a variable high voltage across adjustable stainless steel electrodes immersed in the sample. The digital panel meter records breakdown voltage, ensuring accurate, standardized dielectric assessment in compliance with international norms.

Q: What safety mechanisms are included with this oil test set?

A: The device integrates multiple safety features such as a lid interlock switch, zero start requirement, automatic tripping for overload/overvoltage conditions, and an automatic discharge device. These features collectively provide safe operation and protect users from accidental exposure to high voltage.

Q: When should the electrode gap be adjusted, and what is the standard setting?

A: The electrode gap can be set between 2.5 mm and 4 mm, depending on specific test requirements or standards being followed. The standard recommended and default setting is 2.5 mm, suitable for compliant transformer oil testing per IS: 6792 or IEC: 156 guidelines.

Q: Where can this oil test set be used effectively?

A: Its robust and compact construction makes it ideal for laboratories, transformer manufacturing units, maintenance workshops, and quality assurance facilities in the electrical industry. Its standard lab-bench size and oil-resistant finish ensure suitability for a variety of professional settings.

Q: What is the typical process for conducting a test using this apparatus?

A: Testing involves pouring a sample of transformer oil into the cup, adjusting the electrode gap, and enclosing the chamber. The user then applies voltage via the motorized controller, monitors the breakdown voltage on the digital display, and relies on the digital timer and automatic discharge for precise and safe results.

Q: What benefits does the transparent test chamber provide?

A: The transparent chamber allows users to visually monitor the test in real-time, ensuring that any unusual occurrences or arcing are immediately visible. This feature enhances safety and simplifies test supervision.
