STS Family has the facility to test not conventional CT, VT, Merging Unit (MU), by the IEC 61850-9-2 (SV) protocol.
STS Family generates current or voltage and injects these quantities into primary side of the CT or VT under test.
STS Family then reads the data from the network using its Ethernet port (Sample Values) in order to perform a variety
of different tests, as CT ratio and polarity up to 800 or up to 2000 (with BUX 2000) or 3000 (with BUX 3000). It is
also possible to check the VT ratio and polarity, up to 2 kV. Test of MU.

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 C current
•Low C current
•High DC current
•Low DC current
•High C voltage
•Low C voltage
In addition, there is a high power C voltage output, not isolated from the mains, which supplies the external options
(TD 5000, BUX 2000, BUX 3000, STLG, STCS Booster 20 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 P DS 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.
P DS 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
•C or DC voltage
•High range, up to 300 V
•Low range, up to 3 V
•C or DC current, up to 10
ll 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. n optional trolley is also available.

HARACTERISTICS
3 1 Foreword
STS incorporates a generator with six outputs. When an output is generated, there is voltage also on all other outputs,
unless for the high C voltage.
The generator is made of an electronic type D switching amplifier, followed by a power transformer, which adapts the
suitable current or voltage output.
3 2 Main generator
The main generator has six outputs:
•High C current
•High DC current
•Low C current
•Low DC current
•High C voltage
•Low C voltage
Output adjustment is performed automatically, as a function of the selected test. The following specification applies to
the separate use of these outputs.
For all outputs, the following applies:
•Type of generator. Electronic type D switching amplifier, followed by a high power transformer, with a number
of secondary windings, fort the following outputs: high C current, high DC current, high C voltage. Loop
control of the selected output. The transformer includes also the outputs: Low C current, Low DC current,
Low C voltage, but they are not loop controlled
•Output adjustable from zero to the maximum value
•The specified output power is available at 25 °C maximum of external temperature, and with a power supply
error of 2% maximum. For higher temperatures, the maximum power decreases of 20 V /°C
•The specified output accuracy and THD applies at (25±2) °C, resistive load, and burden less than 20% of the
maximum, currents up to 50% of the maximum. With full temperature range, maximum current and maximum
burden, errors are twice as bigger
•The specified output characteristics may vary for frequencies below 50 Hz and above 60 Hz
•The generated frequency can be synchronized with the mains (with the Power Line Synchronizer option)
•The selected output is shown by a LED

3 2 5 High AC voltage
The output is available on the STS 5000 and STS 4000.
The high C voltage output is coming from the same transformer as high C or DC current, but an HV switch inside the
test set isolates it.

the enable key is turned on
Three voltage ranges are available:
•2,000 V
