PK series microcomputer protection measurement and control panel is applied to 35kV and transformer (distribution) power stations with voltage level, providing intelligent and networked measurement, protection and control functions for high-voltage equipment in the station, and at the same time communicating with the superior master station in real time to realize the comprehensive automation of transformer (distribution) power stations. The main functions of this series of products include: various protection of lines and differential protection, backup protection and measurement control of measuring transformers; Various protection and measurement control of capacitors and motors: bus sectioning, incoming standby automatic switching and other measurement and control functions.

Regular service conditions

Ambient temperature: -50℃~+40℃, and the average temperature within 24H shall not exceed +36℃. Altitude: no more than 2500m. Relative humidity: no more than 50% when the ambient air temperature is +40℃. There can be a higher relative humidity at a lower temperature (for example, 90% at +20℃), and considering the temperature change, moderate condensation is allowed. The inclination of the equipment to the vertical plane should not exceed 5. The equipment should be installed in a place without violent vibration, impact and corrosion.
