Density Monitors for 400kv

This SF₆ Gas Density Monitoring System has been designed to allow the user a greater degree of flexibility for measurements and alarms than that currently provided by gauges with contacts. The system uses SF₆ density transducers which operate with a 6 to 20mA current loop technology for high noise immunity.

2016-3-22cup array, has been designed for a 400KV electron irradiation accelerator in Huazhong University of Science and Technology. Suitable structure has been calculated for the secondary electrons emission. Cooling system is necessary for the detector in the condition of high-intensity ion beams, and it has

2017-9-16Only type tested L.A’s are to be offered for 400KV, 220KV, 132KV 33KV System Voltage conforming to our technical specification and relevant IS and IEC. L.A offered should be similar with ones on which type testing has been carried out as per relevant IS and IEC. Three sets of

Iris Power, founded in 1990, offers sensors, monitors and diagnostic solutions for the assessment of the actual state of generators, motors, dry-type transformers and air-insulated switchgear, so that the risk

The connection from the transformers to the remote OHL is via GIL which runs through a tunnel of approximately 600m in length. The main issues considered for GIL or cable

2018-3-7Experimental investigation of the Performance of 400 kV line ceramic insulators under Pollution is studied. Flashover under densefog conditions on 400 kV Kanpur- Obra line has been investigated. For these investigations four single ceramic insulator discs of the actual line were made available.
