PTE-50-CET

Three Phase Manual and PC-Controlled Relay Test Equipment

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.

CHARACTERISTICS
• Variable three phase Current up to 3 x 50A or Voltage up to 3 x 150V.
• Variable phase angle between 0 – 359.9° (Single or three phase).
• Harmonic selection independent by phase, up to the 7th harmonic.
• Output power: 3 x 100VA.
• Reversible outputs.
• Outputs are fully isolated and electronic.
• Dynamic capability.
• Completely programmable.
• Built-in Timer, 1ms resolution.
• Dimensions: 200 x 442 x 327 mm/25 Kg 8 x 18 x 13 in./ 52 lb.

APPLICATIONS
• Testing of three phase motor protection relays.
• Testing of three and single phase overcurrent and differential protection relays.
• Can be used as a complete single phase unit in voltage, current, and phase as outputs are reversible (V, I, j ).

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.

Key Features

Assisted manual control, The comprehensive and well-designed control board in the PTE units provides fast and accurate operation for the simplest one-shot testing to the most complex dynamic fault simulation

Dynamic simulation, each channel can store two sets of amplitude (voltage or current) and phase angle parameters in memory

Control BUS, allows the interconnection of up to five PTE units in order to use all their output channels simultaneously

Digital instrumentation, including the chronometer, the frequency generator and the injection measurement displays

Selectable frequency and phase angle reference, the sinusoidal output can be chosen from various sources by just pushing a toggle button
