  15. 15. OUTDOOR EQUIPMENTS BALANCING TRANSFORMER 1. Balancing transformer (BT) is used when phase to phase communication system is used for balancing the two LMU 2. The diagram of balancing transformer is shown in figure 3.1. As shown in diagram is very less in size but it is play a vital role in power line carrier communication. Fig 3.1: Balancing Transformer (BT) 04-09-2015PLCC 15
  16. 16. OUTDOOR EQUIPMENTS 1. HIGH FREQUENCY CABLE (HFC):It is used to carry the signal from PLCC cabinet to switch yard 2. LINE MATCHING UNIT: Tuning Device is the combination of R-L-C circuits which act as filter circuit. LMU is also known as Coupling Device. Together with coupling capacitor, LMU serves the purpose of connecting effectively the Audio/Radio frequency signals to either transmission line or PLC terminal and protection of the PLCC unit from the over voltages 3. CAPACITOR VOLTAGE TRANSFORMER: It allows to pass the frequency to line. It provides low impedance path for carrier energy to HV line and blocks the power frequency. Circuit by being a high impedance path easily 04-09-2015PLCC 16

  19. 19. INDOOR EQUIPMENTS PLCC CABINET 1. It is installed in control room. 2. It has two sections: 3.Transmitter: In this, voice frequency (VF) is amplified and then modulated to intermediate frequency (IF) and amplified, modulated into HF and then transmitted. 4. Receiver: In this section HF signal is received and then demodulated from HF to IF and connected to the tale phone. 04-09-2015PLCC 19 Fig-1(a) PLCC Cabinet
  20. 20. INDOOR EQUIPMENTS LIGTHING ARRESTER 1. The ground wires running over the towers provides an adequate protection against lighting called L.A. 2. It reduced the induced electrostatic or electromagnetic voltage. A good light arrester must pass the following properties: 1. It should not absorb any current during normal operation. 2. After the over voltage discharge, it must be capable of interrupting the normal frequency of current 04-09-2015PLCC 20 Fig-2
  21. 21.

  24. 24. BATTERY CHARGER 1. PLCC (Power Line Carrier Communication) works on rectified AC or main power supply. 2. When supply goes off, we use BATTERY CHARGER for proper functioning of PLCC. 3. It provides supply to the PLCC equipment for uninterrupted working. 4. It provides DC to the panel by battery of 48V. In this type 24 batteries are connected in series and individually per battery has approximately 2V capacity. 04-09-2015PLCC 24
  25. 25. ADVANTAGES2 1. The cost is less because no separate wires are needed for communication purposes 2. Power lines have appreciably higher mechanical strength compared with ordinary lines. 3. Power lines usually provide the shortest route between the power stations. 4. Carrier signals suffer much less attenuation because power lines have large cross-sectional area 04-09-2015PLCC 25
  26. 26. DISADVANTAGES 1. Proper care has to be taken to guard carrier equipment. 2. High voltages and currents 3. Due to Reflections attenuation increases and creates problem. 4. Noise introduced by power lines is far more than in case of telephone lines. 04-09-2015PLCC 26
