Transformer protection relay PAS2950D

voltagecurrentoverload

PAS2950D series digital distribution transformer protection, measurement and control device is applicable to the protection, meausrement and control of power transmission and distribution transformers of 35kV and lower voltage level. It could not only be decentralized in switch cabinet and installed on the spot, but also be centralized and installed through screen assembly. (1) Perfect configuration of protection, measurement and control function (2) Powerful measurement function: It has the functions such as harmonic measurement and phase angle display, etc. (3) The design of general software and hardware platforms: It adopt 32-digit high-speed DSP microprocessor, modularized software design and perfect self-check function. (4) Integrated design: The product has the functions of remote measurement, remote control and remote signal, and the interval could prevent mis-locking and give signal prompt. The device has built-in DC operating circuit, and self-adapts to tripping and closing to maintain current. It is flexible and reliable. (5) Humanistic design: The product adopts completely Chinese menu display, calibrates AC quantity with software, provides multiple pairs of tripping output contacts and signal output contacts, and could flexibly set up output contacts.
