Identifying these concerns, Enco mm has fully worked on the new w ay of detecting lightning strikes by Radio Frequency. This system is being utilized by KEPCO(Korea Electric Power Corp oration) to check for damage caused by lightning to tr ansmission towers and other fac ilities by the lightning. Transmitter1 Transmitter3 Transmitter2 Lightning Current Necessity of WLS 2002 Necessity of WLS 2002 2 WLS2002 is installed on the transmission tower. When the tower is struck by lightning , the transmitter transmits a RF signal. The receiver displays information, which will be used to discover the exact location of a lightning strike. Transmitter Transmitter 3 Application Application Transmitter1 Transmitter3 Transmitter2 Lightning Current A. The transmitter1 is 1234567, Transmitter2 is 1234568, and Transmitter3 is 1234569. B. When lightning strikes transmission tower #1, the transmitter on the tower transmits the ID number (1234567) of #1. C. An inspector can easily recognize the transmission towers struck by lightning in real- time. 4 Ratings Ratings ~ ~ L250 X L250 mm L250 X L250 mm Angle Angle Structure Size Structure Size 66/154 / 345 / 765 66/154 / 345 / 765 Rated Voltage Rated Voltage (kV) (kV) Without arc Without arc - - horn horn With arc With arc - - horn horn WLS 2002 WLS 2002 Type Type ~ ~ Φ Φ 620 mm 620 mm Pipe Pipe ■ Applied Standard : Technica l Specification Of KEPCO 5 ‰ ‰ Initial Display Initial Display Receiver Receiver LCD DISPLAY Mode key Read key [ KEY FUNCTIONS ] - Mode Key : Setting M enu and confirming. - Read Key : Reading Message and choosing function [ LCD DISPLAY ] - Graphic LCD Module display s the received messages 6 ‰ ‰ Power ON Power ON - When the receiver turns on, it displays Encomm Logo for 4 secon ds, and then it goes to initial display. - On the initial state, MENU mode can be started by pressing the Mode key for 2 second - Pressing the Read key, it advance you to the next menu- Pressing the Mode key, it will return you to the main menu - The display is returned to the main menu by pressing the read key - You can then alter the values on the display- After altering the values, you can confirm the values by pres sing the Mode key - After confirmation, the displ ay returns to the Main Menu 7 ‰ ‰ MENU MENU * CLEAR ALL MENU :1.

FCC ID : SGLWLS-2002 Specification : 47 CFR 2.1046 (a) Test method : ANSI/TIA/EIA-603-2001, Paragraph 2.2.1 Measurement Procedure: - For Conducted measurement, The EUT was connected to a resistive coaxial attenuator of normal load impedance, and the unmodulated output power was measured by means of an R.F. Power Meter. - For Radiated measurement, Effective Radiated Power Output Measurements by Substitution Method according to ANSI/TIA/EIA-603-A-2001. The EUT was placed on a wooden turn-table 3-meters from the receive antenna. The receive antenna height and turntable rotation was adjusted for the highest reading on the receive spectrum analyzer. A half-wave dipole was substituted in place of the EUT. This dipole antenna was driven by a signal generator and the level of the signal generator was adjusted to obtain the same receive spectr…
