Precision at your fingertips
The WT5000 Precision Power Analyzer – Transformer version is the world’s most accurate precision power analyzer guaranteeing its basic power accuracy of ±0.008%. Operable by touch and hardware, the WT5000 offers an intuitive measurement experience for power transformer testing. Define and use event triggers and custom computations to suit your application needs and view measurements in numeric, waveform, bar, vector or trend formats.
Best Accuracy at Low Power Factors
The instrument offers the best accuracies at low power factors for commercial frequencies of 45 to 66 Hz. Low power factors have a dramatic effect on accuracy. It offers an accuracy of 0.6% of the reading for measurement at a power factor as low as 0.01 at 100 V and 1 A. This makes the unit ideal for the precision testing of transformer losses according to the IEC60076-8.
Accredited calibration certificates included
When every kilowatt lost beyond specified limits can cost thousands of dollars in fines, it becomes necessary to have confidence in the measurement of power losses. To address this, the WT5000 Transformer Version is optimized by ISO17025 accredited calibration at 53 Hz at power factors of 1, 0.5, 0.05, 0.01 and 0.001. Additional ISO17025 accredited calibration up to 100 kHz ensures performance when measuring distorted waveforms, for example during no-load loss current measurements of transformers. This enables the integrated transformer measurement system to measure power losses with great accuracy and to determine any drift as described in the IEC60076-8 Standard.
