The basic STS function is to generate current and voltages, as requested by the type of test to be performed; only one
test at a time. The test is selected on the LCD screen by means of the multi-function knob. Test results are kept in local
memory or in a USB card, and can be transferred to a PC later, along with settings.
The capacitance and Tan(δ) measurements with TD 5000 can be performed on CTs, VTs, CBs, PTs and bushings.
STS 5000 contains a generator, with the following six outputs:
•
High AC current
•
Low AC current
•
High DC current
•
Low DC current
•
High AC voltage
•
Low AC voltage
In addition, there is a high power AC voltage output, not isolated from the mains, which supplies the external options
(TD 5000, BUX 2000, BUX 3000, STLG, STCS Booster 20 A DC).
In local control mode, the selected output is adjustable and metered on the large, graphic LCD display. With the control
knob and the LCD display it is possible to enter the MENU mode, which allows setting many functions: this makes STS a
very powerful testing device, with manual and automatic testing capabilities, and with the possibility to transfer test
results to a PC via USB, ETHERNET or Pen Drive.
In the PC control mode, the PADS program allows performing the same tests as in the local mode, with the same control
windows. It allows also downloading, displaying and analyzing test results obtained in local mode.
PADS operates with all WINDOWS versions.
The ease of operation has been the first goal of STS: this is why the LCD is graphic, and so large. With it, the dialogue in
menu mode is made easy. Besides, all STS outputs relevant to the selected test are continuously measured, and output
values are displayed, with no extra effort to the operator.
STS feature four measurement inputs:
•
DC voltage, up to 10 V DC
•
AC or DC voltage
•
High range, up to 300 V
•
Low range, up to 3 V
•
AC or DC current, up to 10 A
All inputs, unless the 3 V and 300 V voltage measurements, are isolated among them, and allow measuring CT or VT
outputs or any other source.
In all STS models, it is available a digital input, which accepts an input, which can be voltage free, or with a voltage up
to 300 V. It allows measuring the time response of a protection relay. It is also possible to test the M.V. CB’s timing: the
time is stopped when the injected current is opened by the CB.
The instrument is housed in a transportable aluminum box, which is provided with removable cover and handles for
ease of transportation. An optional trolley is also available.
