• Product Description
KW-1000 Digital Fault indicator Monitoring System for on-line monitoring line running, fault condition and ineparameters,
is a set of distributed monitoring and centralized management,instant notification type inteligent electricpower line management system.
In the system,the detection ofterminal distribution mounted on the power transmissionnelwork to monitor the location of the
(such as: every branch and accidents period, cable joint, etc.) Can real-timemonitorline operation, when short circuit fault,
ground fault(earth faulty), faut line, theft cases,etc.occurs in line, Monitor centelin the alarm display within dozens of seconds,
and send the information to the phone ofmaintenance personnel who ison duty. Can display the line load current and temperature changes.
You can never leave home, a comprehensive graspline operation, And can according to user's need to increase other monitoring content.
