SEL-T400L微機保護裝置的調(diào)試方法
2016-4-21 閱讀(739)
KEY FEATURES AND APPLICATIONS
1 ms traveling wave elements: TW87 and TW32.
4 ms time-domain elements: TD21 and TD32.
Easy to set and less dependent on short-circuit studies.
Nearest-tower fault location, with and without communications.
Time-synchronized, high-resolution data recorder with 1 MHz 18-bit sampling rate captures transient events.
Complements your traditional protection and gives you speed.
SEL time-domain and traveling wave technologies are delivering dramatic reductions in transmission relay tripping times. Faster tripping means more megawatts transmitted, better stability, improved safety, less damage to insulators and transformers, and reduced fire risk
Edmund O. Schweitzer, President, SEL
