PTE-100-C / PLUS / PRO
The PTE-100-C and the Plus and Pro versions were designed as powerful, rugged and flexible tools for the wide diversity of maintenance jobs in substations and transformation centers.
Both feature a 1000-VA voltage regulator and highly accurate digital instruments that provide the quality and effectiveness required for in-field testing of power-demanding electromechanical relays, as well as static, digital and the most sophisticated multi-functional numerical relays where precision and ease of use are essential. Digital chronometer, autorange ammeter and voltmeter, as well as four adjustable current output taps, AC and DC voltage outputs, auxiliary DC source, automatic overload an thermal protections, PC communications and a comprehensive set of external measurement functions are just a few of the most outstanding features that we have packaged for you in a compact, robust and lightweight piece of equipment that is being used by industry professionals in more than 55 countries worldwide.
Besides the 1000-VA output featured by the three models, the Plus and Pro versions include an independent AC voltage source that can be adjusted in amplitude, frequency and phase angle to further extend the comprehensive number of protection relay types that can be tested. Existing PTE-100-C units can be easily upgraded to a Plus or a Pro by just installing the optional PTE-FCL or PTE-FCN modules respectively into the unit’s lid in a few minutes.
The PTE-100-C’s design is mainly appreciated for its unbeatable manual testing characteristics. However, a number of software products for Windows® is available to attain a certain degree of automation and assistance in the testing and reporting tasks. Apart from the standard RS-232 communications port, every test set in the PTE range features the EuroSMC’s exclusive BUS-PTE® integration bus that allows them to be interconnected to further extend their applications field.
Due to their outstanding output power, comprehensive set of test functions and compact size, these products are a must-have for maintenance work in any plant, substation or transformation center. The PTE-100-C and the Plus and Pro versions are also appreciated as unbeatable instruments in laboratories and specialized training sites where the diversity of tasks require a wide range of current, voltage, frequency and phase angle control applications.
Not only is it possible to test any protective relay, but also to determine a CT’s saturation point with voltages up to 250V, and to evaluate the output quality of an autonomous oil-based power generator.
Instantaneous overcurrent protections up to 250A can be tested from the primary side, and auxiliary DC power can be supplied to small three-phase circuit breakers during the test process.
The built-in digital programmable chronometer can measure positive and negative pulses, or time the activity of a normally open or closed contact with no voltage or charged up to 250V, with a 1-millisecond accuracy.
EASY TO USE
All the controls and displays are intuitively located and ergonomically designed.
The thick regulation knob provides an accurate and smooth adjustment of the test quantities. Four current ranges deliver the available 1000 VA power regardless the working scale, and allow for fine adjustment and distortion-free injection even on the biggest electromechanical loads.
The test set is protected with automatically resettable overload and thermal trips, and the tested device can also be protected against accidental mistakes like excessive current or too long injection time.
The auxiliary DC supply provides an independent, continuous 0-250 V regulation and is short-circuitable.
The “preset” function allows the adjustment of the test current previous to the actual injection, which saves time and avoids stressing the relay’s input at high current test values.
