The Primary current sensor uses the same sensor technology as the original Rogowski coil. The True RMS inductive sensor does not use magnetic materials. The opening of the sensor is electronically closed and external currents are electronically rejected.
The accuracy, external current reject, and range of currents measured by the patented amp sensor substantially exceed the performance of the best clamp-on sensors. The key feature of the unit is the ability to leave it deployed on the line to record readings every 15 minutes for 90+ days. It easily attaches to the line with a standard insulating bar. Once on the line, it immediately begins to collect and record the primary current on the line.
The Primary current sensor is equipped with a 433M wireless port for communicating the recorded data into the userâ??s PC. The data is downloaded through GF2018S PC-Link Software, which allows the user to download, view and query the data stored on the Primary current recorder.
The housing of the Primary current sensor is made of ABS+PC and is built to operate safely, even in severe utility environments. It is resistant to shock, waterproof and resistant to flame. It also operates within a wide temperature range. The Primary current recorder has a screw insulation bar of installation, which allows it to hang on the line securely in all weather conditions.
PC-Link Software is a user-friendly software interface that allows the user to download, view, graph and export data from the Primary current recorder into Microsoft Excel. The data directly transfers from the Primary current recorder into Excel through an 433M Port.
