Low Voltage Surge Tester SWT4

 

 

Description

LV Surge Tester SWT 4 is a powerful equipment to pin-point underground power cable fault by acoustic method with a suitable Surge Wave Receiver.

Occurrence of cable fault cannot be avoided due to many factors. Long outage of a cable from service results in heavy loss of revenue to the power distribution company, production loss to industries as well as unpleasant condition to general. This requires an efficient equipment capable of locating the fault in minimum possible time and restoring the supply.

In power cable fault location most of majority faults pin-points test are carried out using a high voltage and high energy surge wave tester. LV Surge Tester SWT4 offers 500 Joules of energy on 2 and 4kV selectable ranges, which allows its use on low voltage power cable networks effectively.

It is also used to pin-point the underground cable faults in low voltage power cables with the help of highly sensitive and sensitive surge wave receiver. It is also used to pre-locate cable fault distance with the help of suitable pre-locator unit in impulse current (ICM) mode.

 

Application

It is used to pin-point underground cable faults in power transmission, distribution cable networks in acoustic mode with the help of suitable surge wave receiver.

 

Features

Optimized surge energy for switchable capacitors values for each range.

Pin-point location of cable faults in low, medium and high voltage cables by acoustic method.

Output voltage selectable in two ranges 2 - 4 kV.

High energy of 500 Joules

Full energy delivering capacity at each select range.

Continuously variable output voltage from 0 to 100 % of selected range.

Single manual Impulse for cable fault pre-location.

Fully protected operation with safety interlocks.

Pre-location of cable fault distance with suitable pre-locator unit on ICM mode.

Automatic discharging facility of cable under test, in case of power failure or after switching off.

Continues operation for extended period in case of pin-pointing difficult cable faults.

Rugged construction and easy to carry on site.

 

Working Principle

The LV surge tester ignites an arc or spark at the fault, these results in a transient at fault point, i.e. a spreading and repeatedly reflected traveling wave between the fault point and the surge tester. Inductive couplers record this transient wave with the help of a pre-locator unit and convert in to fault distance.

Surges of high energy are applied to the fault at the set voltage and time interval for pin-pointing the exact spot on the cable length. 

These surges create noise and vibrations at the fault site. The intensity of the noise and vibrations get attenuated during their travel to the ground surface. A ground microphone and a sensitive surge wave receiver are carried out on the route of the cable at a pre-located area and pin-point the exact spot of the fault in minimum time.

 

Function

The LV surge tester used for fault pin-point location is basically a variable DC high voltage power supply, connected to a high voltage capacitor bank. The value of capacitance is usually selectable by parallel, series parallel and series combination. This combination being linked with suitable voltage taping to give the constant energy output on low voltage / high capacitance or high voltage / low capacitance. This high voltage output is supplied to the cable under test through a spark discharge device.
