We are offering the following services :

Single Impulse and repetitive surges

The instrument has single impulse mode, by which a single shot of surges is applied to the fault for ascertaining the level of fault breaking.

This mode is also necessary for pre-location tests to be carried out with other instrument compliments. Repetitive timings of 4 and 8 second intervals are suitable for pin-pointing the fault.


Safety Controls

SWT 4 employs safety controls for personal and instrument safety. Variac zero, HV switch interlock, output cable plug interlock, instant earth discharge of internal capacitor bank and the cable under test at the time of switching off/tripping offer absolutely safe operation condition. Tripping with indication and non operation of the instrument due to over heat condition caused due to any problem, safeguards the instrument for any damage. This safety control resets automatically after cooling down to normal condition.

Single Impulse and repetitive surges

The instrument has single impulse mode, by which a single shot of surges is applied to the fault for ascertaining the level of fault breaking.

This mode is also necessary for pre-location tests to be carried out with other instrument compliments. Repetitive timings of 1.5, 3 and 6 second intervals are suitable for pin-pointing the fault.


Safety Controls

SWT 16 employs safety controls for personal and instrument safety. Variac zero, HV switch interlock, output cable plug interlock, instant earth discharge of internal capacitor bank and the cable under test at the time of switching off/tripping offer absolutely safe operation condition. Tripping with indication and non operation of the instrument due to over heat condition caused due to any problem, safeguards the instrument for any damage. This safety control resets automatically after cooling down to normal condition.
