PA3000

Four-channel, Multi-phase AC/DC Power Analyzer

TEKTRONIX 

Datasheet

Three phase motor drives

Key tests include output power, efficiency, and harmonic analysis. The PA3000's PWRVIEW software offers wizard-driven setups to simplify 3-phase 3-wire

and 3-phase 4-wire test configurations.

Example test configuration and measurement results for testing three-phase motor drives

Output power

Dedicated PWM Motor drive mode to test output voltage waveforms

High frequency sampling with digital filtering in PWM mode, to reject

the carrier frequency and detect the motor frequency while still using

pre-filtered data for all measurements

Optimized for steady-state three phase power measurements on the

output.

Efficiency testing

Dedicated application wizard on PWRIVEW software and Math function

on PA3000 enable easy setup for motor drive efficiency

Available 3 Phase 3 Wire configuration makes it easy to measure three

phase inputs and outputs with four channels for system efficiency

Four analog inputs rated at ±10 V and two counter inputs with 1 MHz

bandwidth for torque and speed measurements enable measuring

complete mechanical system efficiency

30 A internal shunt and available high accuracy current transducers for

high power testing in kilowatt range

Standard ±15 V power supply on the back panel to power external

current transducers
