Enhancements for power analyser

Yokogawa has launched a new Current Sensor Element and upgraded the firmware for its WT5000 Precision Power Analyzer. The enhancements are designed to help companies improve performance when developing or evaluating electronic devices such as Electric Vehicle (EV) related equipment or systems for solar and wind power installations.

The new Current Sensor Element runs off the internal DC power supply of the WT5000, making external power supplies unnecessary. This makes set up for measurements easier as the only things required are the current sensor and a connecting cable.

Three sensor connection cable lengths are available – 3m, 5m and 10m. This helps take account of varying test bench layouts, where the power analyzer may not be located right next to the device under test. The three different cable lengths allow users to select the one most suitable for their set up while keeping the leads as short as possible.

Firmware is also upgraded, with the Data Streaming function now supporting a 50 ms to one second update rate. On the previous version, when using the Data Streaming function, the WT5000 only offered an update rate – measurement interval – of one second. This meant that all electrical parameters, such as power and Urms and Irms, were calculated over a period of one second.
