INTRODUCTION
The PTE-100-C PRO Relay Test Set is designed to test protective relays
based on single-phase current and /or voltage measurement.
Its small size, excellent output power and accuracy, quality features, and
ease of use, make this product one of the best choices available in its kind.
To achieve this goal, EUROSMC collected the opinion and suggestions of
various professionals and companies of recognized prestige and experience
in protective relay maintenance and commissioning. As a result, the PTE-
100-C PRO features the following unique characteristics:
•Robust mechanical and electrical construction.
•Great portability.
•Built-in measurement features to avoid carrying a large number of
instruments.
•Results printout capability, when taking notes is usually difficult.
•Software-assisted closed-case calibration with a Windows PC.
•Functions to protect the relay being tested.
•Easy, intuitive operation.
The PTE-100-C PRO includes all the accessories needed for testing, such as
cables, clips, nylon bag for transport, spare fuses etc. as standard equip-
ment.
We appreciate your suggestions about the PTE-100-C PRO and this ma-
nual, in our commitment to improve our quality. Our technical staff will be
pleased to help you on any difficulties or questions that you may have.
Thank you for choosing EuroSMC products.

GENERAL OVERVIEW
Technology
The PTE-100-C PRO combines state-of-the-art digital technology with the
traditional regulation method based on a variable autotransformer and
transformer.
Analogue and digital electronics convert signals in- and out from the unit in
order to be processed and displayed by an 8-bit microprocessor.
The power section is based mainly on electromechanical components.
The unit’s layout is arranged in modules and the number of moving parts is
kept to a minimum for easy and safe operation.
Power Section Design
Classical, direct regulation and transformers are used to generate and con-
trol the high 1,000-VA power output, as shown in the following diagram:
1. An internal relay connects the main power supply to the variac un-
der no-load conditions.
2. The single-phase variable autotransformer (Variac) regulates the
voltage at the primary winding of the output power transformer.
3. A static switch (Triac) guarantees a clean connection and discon-
nection of the Variac from the power transformer’s input.
4. A toroidal transformer guarantees the insulation of the output from
the main power supply.
5. A current measurement transformer, with one primary winding and
two secondaries with 250:1 and 50:1 respective ratios, is con-

nected to the ‘zero’ output tap of the power transformer. Measure-
ment range switching is automatic.
Auxiliary Voltage Supply
By means of a transformer with multiple secondary windings, the PTE-100-C
PRO features two independent auxiliary voltage outputs:
•Out 3 is a variable 0-250 VDC stabilized, electronically protected
supply with a dedicated ON/OFF switch, and
•Out 4 is a fixed 110 VAC. This fuse-protected output is permanent-
ly active whenever the equipment is switched on.
Measurement and Control
Analogue input is converted to digital values before it is processed and dis-
played. The following external or internal analogue magnitudes are meas-
ured:
•Voltage.
•Current.
•Phase angle.
•Temperature.
Displayed and/or used values like Impedance or Power are automatically
calculated from these magnitudes by the microcontroller.
