Description
The Megger DET3TC is the ground testing model with the capability of testing on-site grounds without disconnecting the utility connection. The DET3TC includes a current measuring function for ART (Attached Rod Technique) testing capabilities. It is designed to meet stringent safety standards and is rated CAT IV 100V. The DET3TC has been designed to be easy to use – a large selector switch makes selection of 2 or 3 pole tests easy with gloved hands – and the design makes the fitting of shorting links to perform 2-pole tests a thing of the past. A large, clear, easy to read LCD and thumb-sized test button also makes the instrument particularly well suited to the outdoor conditions of ground testing. In addition to this ease of use feature, the ground tester automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. The DET3TC also includes a voltmeter to enable measurement of ground voltage. It can measure resistance from 0.01 ohms to 2 kΩ. Also, to allow accurate testing in noisy environments, it is capable of rejecting noise up to 40V peak to peak. By using the optional ICLAMP with the DET3TC, the user can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA. Applications for the Megger DET3TC:
– Primary and secondary electrical grounding systems
– Utility pole grounds
– Lightning protection systems
– Residential grounds
– Machinery safety grounds
– Computer and communication system grounds
– EMI/RFI system grounds
– Antenna and pedestal grounds
– CATV system grounds
