ZJS-102 Insulation monitoring system is a highaccurate and secure online monitoringequipment for DC system insulation. It isdesigned for the measurement of differenttypes of ground fault, insulation decreasing,AC signal interruption, DC signal interruptionand so on. Monitor detect DC leakage current, mixed withbalanced & unbalanced bridge detectionmode, can display leakage current of each subexport loops. It integrates voltage transientcapture and current synchronous detection,records voltage and current fault curves toachieve instantaneous grounding monitoringand line selection alarm functions.
High humidity environment is a big impact factor of power transmission and transformation equipment, it will bring discharge, flashover will eventually cause the switch to trip, even burning down equipment caused a large-scale blackout. Switchgear, electrical cabinet, exchange control cabinets, outdoor terminal boxes, Due to the compact internal equipment installation, wet and condensation will be more serious consequences. At present, most user choose heating, ventilation and other method to prevent condensation. but in some well sealed cabinet and high temperature environment, traditional heating and exhaust air method is hard to work well. Blue Jay company developed DH series using semiconductor technology, in a certain place to lead controlled condensation, make the cabinet interior humidity fall to safe value. It designed ultra-small install size, high efficiency energy-saving, do not need extra heater and fan wiring. And comes with the data acquisition module for remote monitoring, It's an efficient and reliable device to replace the old thermostat and heater / fan combination.
HVD high voltage indicator is adapted for indoor electrical panel, used in MV / HV switchgear. It is connected via internal wiring to capacitive sensors inside the switchgear. Rated voltage 3~40.5kv, operation frequency 50Hz network to display the electrifying situation of the high voltage loop where the device is mounted. This integrated voltage detecting system is used for continuous operation. The condition "voltage present" is displayed by three LED indicator.
STM wireless temperature monitor can help medium-low voltage switchgear operators and maintenance engineers, to reduce safety risks from sudden temperature increases in switchgear components. It provide 7*24 hours switchgear monitor for critical busbar joints. Multiple styles of remote sensors node can deal with different electrical contacts, W3000 support max 32 monitoring node for single switchgear. Panel mount HMI unit have acousto-optic alarm and DO port, user can free to build various automatic alarm / control system. Equipped RM485 port can connect existing SCADA system for remote sensering control. It can protects your electrical assets from costly outages; while increasing safety via remotely monitoring equipment. This also increases asset integrity, and minimizes downtime.
