SMC PTE50-CET Three-Phase Relay Tester

Three-phase Relay Test Set up to 50A or 150V AC. The PTE-50-CET equipment is a universal, portable, test system with three outputs to test single and three phase protective relays.

The equipment also allows optional connection to a computer for either automatic testing of relays or control of the equipment using Windows compatible software. Even the adjustment and calibration of the equipment is made by software, supplied with the units, which permits calibration and/or adjustments in the outputs, without any manual hardware setting. (Closed Case Calibration). In summary, the PTE-50-CET is an equipment which offers all the characteristics and functions needed for protective relay testing, in a manual or automatic mode, and in laboratory and/or for on site testing.

The Electronic PTE Test Equipment Range
The electronic PTE test equipment range has been designed for maximum efficiency and simplicity when testing protective relays in the field. These universal, rugged and powerful units provide the required accuracy and performance to test any electro-mechanical, static, or numerical relay. Output waveforms are digitally synthesized, and completely isolated from the mains supply. The signal is then electronically amplified to attain up to 50 A or 300 V with an effective power of 100 VA.

Flexibility
The range includes four products: the PTE-300-V, with three output channels, and the smaller PTE- 100-V, with one channel only, are mainly designed for voltage-related protections like generator, motor and synchronizing relays. The other two (PTE-50-CET and the one-channel version PTE-50-CE) are specially powerful in current-based testing.

Power
Behind the 100-VA output power in the PTE channels, you will find a generous duty cycle and a great number of test resources. For example, several channels can be controlled from a single button, even if they belong to various interconnected units, thanks to the master/slave function. And you can refer the phase angle of each channel or the base frequency of the harmonics function to an incoming signal from an external generator, or setup ROCOF frequency ramps in less than one minute without a computer.

The PTEs feature an idle power mode to save energy and keep the amplifiers cool when testing low impedance relays. Each output channel provides an independent neutral, which enables the interconnection of two or more channels in series or in parallel with absolute freedom. The optional PTE-SER plug allows the injection of up to 50A with a compliance voltage of up to 60V in the PTE-50-CET.
