Description

1. 3-point test method to test the grounding resistance; one time installation; able to achieve the tested resistance by on-line software and APP, also on site;
2. Alarm trigger value can be set by push-button, with audible and visual alarm; and interval time of auto-test can be set too;
3. Through on-line monitoring system, can indicate the tested grounding resistance, grounding voltage, lightning intensity. And times, grounding wire break or not, environmental temperature, environmental humidity and history record, etc.
4. Applications: able to remote test the grounding of belows: building; power transmission pole; underground mine equipment; petrochemical industry; communication base station; electricity converting and transformer station; railway facilities electric installation, etc.
