1. INTRODUCTION
The PTE-50-CE is designed as a Portable Single phase unit that allows the user
to test, as stand alone unit or in combination with others, all type of protective
relays.
Extremely compact and rugged, this unit incorporates the latest in the modern
microprocessor technology to achieve unbeatable output characteristics in terms
of power, accuracy, low distortion, and dynamic capability. This technology
allows the unit to perform, without any external accessories, various specific
functions very often used in the relay testing.
All the output signals are digitally generated, amplified and controlled by the
internal IGMs (Intelligent Generation Modules) in terms of amplitude, phase and
frequency. A high accuracy and stability are obtained in the output waveforms,
which are absolutely independent of the main supply.
Contained in an aluminum IP-65 case, with a membrane keyboard that allows
full manual control, and a RS-232 com port for computer control, the PTE-50-
CE offers the best features actually available for on site manual or automatic
relay testing.

1.1. MAIN FUNCTIONAL FEATURES
The following are the more outstanding functions/features that the PTE-50-CE
has:
a) TIMER MEASUREMENT
Used when measuring the timing response of relays during test. The digital timer
which is incorporated in the PTE-50-CE has a resolution of 1 ms and contains
all the necessary controls to select the starting and stopping of the timer whether
it is external or internal, or when using the monitor signal or via PTE-BUS.
b) AVAILABLE REFERENCES
The power output has three different references available:
oThe main supply phase (Line).
oThe PTE BUS (BUS).
oThe External Phase Reference (current or voltage).
c) POWER OUTPUTS
The current or voltage outputs are available, up to 50 A in four ranges and up
to 150 V in two ranges respectively.
All the outputs have a dynamic capability. The output regulation can work
independently or linked in a three phase system, when PTE units are working
together interconnected through the PTE BUS, any combination of dynamic steps
to 2nd values, can be selected in amplitudes and phase angles for any type of
fault simulation.
d) EXTERNAL REFERENCES INPUT
Can be synchronized, in terms of frequency and phase with any external signal,
from 0.1 to 25 A in current, and from 5 to 300 V in voltage.
e) SIGNAL MONITOR
The unit has a Signal Monitor input that can work with dry contacts or with
voltage signals from 5 to 250 V ac or dc.

f) RS-232 COM PORT
Used to control the equipment from an external computer, can be used to
perform the following:
oSoftware calibration.
oAutomatic testing.
g) PTE BUS
Allows the interconnection with any other unit of the PTE RANGE.
h) EXTERNAL TIMER CONTROL OUTPUT
Delivers a pulse signal, dry contact type, of 20 ms duration. This can be used to
start an external timer, for timing measurements. This signal is produced every
time one of the power outputs changes its status, or the Step key is activated in
amplitude or in phase.

2. OPERATIONAL PRINCIPLE
2.1. GENERAL
In this section a general overview of the operational basic principles on which
the PTE-50-CE is based, are given in this section.
The PTE-50-CE unit has 3 main functional independent blocks, they are:
oFront Panel.
oIntelligent Generator Modules (IGM).
oPower Supply.
2.2. FRONT PANEL CONTROLS
Allows the user to communicate with the power output section of the unit in a
manual way, or using a software program. To achieve this, it has the following
sections:
Displays and LED indicators: indicate the various selections made by the
operator and the status of the unit:
oPress key controls: this is a membrane keyboard with acoustic
feedback, in which the various different functions available in the unit
are selected.
oMulti-turn control knobs: these are rotative pulse generators that are
used to make the different selections desired on the displays indicators,
in an easy and fast manner.
oMonitor taps: contain the circuits to detect the status of the signals
applied in these taps

Operation Manual
13
Figure 2: Front Panel Block
oExternal Reference Taps: contains the circuits to synchronize the power
outputs to the phase and frequency signals connected to these taps.
oCommunications: the PTE units have the capability to communicate
with some external control devices by RS-232 (allowing the user for
printing results and calibration from the PC) and by BUS-PTE, for
interconnection with PTE RANGE units and control of these by a
computer.
oInternal Bus Interface: establishes the communication between the
Front Panel and the Intelligent Generator Module, via the
microprocessors included in both.
oTime Generator: it generates the high accuracy time reference
necessary to generate the internal phase and frequency.
oOutput taps: these are the taps of the auxiliary voltage supply of 110 V
ac, the power output taps, and the tap to start an external timer.
oMicrocontroller: it is one of the most important parts of the unit, which
as its name indicates, controls or establishes the flow of information
between all the functional blocks previously mentioned.

2.3. INTELLIGENT GENERATOR MODULE
Essentially, the IGM is a linear power amplifier, controlled by its internal
microprocessor. It produces the sinusoidal signal in the frequency and the phase
selected. This is amplified and adapted by a transformer in the selected output
range. This generator also feedback’s the output level in voltage, current, and
phase, to the generation stage, thus achieving a high accuracy output.
As shown in the block drawing and in the front panel control functions, a
microprocessor is in charge of supervising all the functions of the generator
modules. They receive the output measurements and make the corrections
necessary in amplitude and phase to obtain the desired accuracy. Also they
store the calibration parameters, and use them to correct the selections made
from the Front Panel.
Figure 3: Intelligent Generator Module
2.4. POWER SUPPLY
This groups contains the transformers and switching power supplies which supply
and energizes the front panel block and IGM.

3.2.1. CONTROL KEYS AND KNOBS: Selecting the function mode
This section describes how to select the timer mode for the starting/stopping of
the timer, the timer reading, and how to reset it. The keyboard for the timer is as
follows:
This key works in a sequential way, that is to say by pressing
this key; the LED’s will indicate the different selection
combinations. There are 6 different possibilities to choose
from, see 3.2.2.
This key works in a sequential way, each time this key is
pressed, the reading in Display 1 located on the left-hand side
will change. This will display seconds or the number of
frequency cycles in alternating current.
Each time this key is pressed the timer will reset to 0, allowing
the operator to perform the next test. If the timer is not reset,
all the outputs and displays will remain on hold and blocked.
This key allows the selection of the Timer whether it is internal
or external. Each time this key is pressed the selection will
change from one to another. There are 2 VISUAL LED’s
associated with this key.

3.2.2. VISUAL INDICATORS AND DISPLAYS
oFunction mode indication
There are 6 green LED’s of 3 mm. When these are lit they indicate
mode function the equipment has. These LEDs are associated with the
Mode key:
a) START Mode indicators:
These 2 LEDs indicate the start mode of the Timer in
relation to the output control ON/OFF and to the 2nd Value
Step press key. These 2 LEDs are 3 mm and green. Only
one can be used at the same time:
When the upper LED is lit, it indicates that the Timer will start when:
oThe output control is activated (ON)
oWhen there is a Step to 2nd Value.
oWhen a contact is closed at the input of the external timer.
oWhen this LED is flashing it indicates that the Timer is in BUS mode,
meaning that it will start when there is a positive event in the BUS.
When the lower LED is lit, it indicates that the Timer will start when:
oThe output control is deactivated (OFF)
oWhen a Step to 2nd Value is deactivated.
oWhen a contact is open at the input of the external timer.
When this LED is flashing it indicates that the Timer is in BUS mode, meaning
that it will start when there is a negative event in the BUS.
b) Stop Mode Indicators
These 2 LEDs indicate the stop mode of the Timer in relation
to the Monitor state. These 2 LEDs are 3 mm and green.
Only one can be active at the same time .
