We design and develop a superlative range of DC high voltage test sets that are designed for testing various high voltage electrical equipment like cable fittings, 11 KV and 33 KV cables and switch gears. Our cutting edge instruments are also used by many of our clients in their high voltage installations for testing purposes. The tests are initiated by first supplying the desired voltage and then checking the leakage of current. These leakages are indicated by the meters of these instruments. The indications calculate the insulation resistance and dielectric strength of the devices and equipment that are being tested with these instruments. These test sets are compact and housed in a sheet metal box. Features

Sakova AC high voltage test sets are designed for testing various electrical equipment and consist of a double wound HV transformer with the high tension end is brought down and ended on a spring loaded rod for testing up to the rating of 5 KV. The last end of the high tension winding is also brought down, through intermediate circuitry and is ended on the earth connection. If the current in the under test equipment increases above the prescribed value, the intermediate circuitry allows for the tripping the supply to the high tension transformer. We have equipped it with the provision of a zero start interlock switch and variac which allows the slow application of high voltage to the test specimen. We have provided these instruments with the indicating lamps on the control panels that for indication of Mains on and H.T. on. It is also provided with a voltmeter to effectively indicate the high output voltage. If at a point of time, the system under test system faces the failure the power supply to the voltmeter is not interrupted whereas the power supply to the HV transformer is instantly switched off. We offer these testers of 10 KV rating housed in a single sheet metal covering while those above this rating consist of HV transformer and a control unit that is made from the sheet metal itself. We manufacture them up to the output range of 60KV. Features

• Zero Start Interlock switch
• Different AC outputs up to 60 KV
• Tests leads for ranges up to 5 KV
• Automatic tripping
• For output voltages above 10 KV, separate control and transformer units

We manufacture and export a diverse range of oil test sets for our clients across the global markets. These quality approved instruments are used for testing the dielectric strength of the insulating liquids of a high tension transformer. These insulating liquids must possess a high dielectric strength. Their dielectric strength is measured by passing a very high voltage through them. If the insulating liquid fails in the test the device will show a spark between its two electrodes. We manufacture these oil test sets in different models and voltage ranges conforming to the quality standards like IEC-156 and IS: 6792/1972. Our oil test sets consist of different parts like H.T. transformer and oil test cell (with electrodes & gauge), control panel, fitted in a sheet-metal cabinet with an acrylic covered housing for the oil test cell.
