PTE-50-CET

Three Phase Relay Test Set (50 A, 150 V)

The PTE-50-CET equipment is a universal, portable, test system with three outputs to test single and three phase protective relays. 

The equipment comprises of three independent output channels that can be selected as current or voltage. 

This enables the unit to be used as a complete single-phase equipment (voltage, current, and phase angle between them) 

or, with channels synchronised, as a three phase current or three phase voltage generator from a single phase mains input.
The unit is extremely compact and rugged. 

The design incorporates the latest in modern digital microprocessor technology to achieve unbeatable output characteristics 

in terms of power, accuracy, low distortion, and dynamic capability. 

This technology allows users to test many different specific functions required in relay testing, without the need of additional accessories. 

All output signals are digitally generated, amplified, and internally controlled by the IGM’s (Intelligent Generator Modules), 

which interpret the orders received from the front panel to produce a highly accurate, stable, and low distorted output, independent of the voltage supply. 

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.
