INTRODUCTION

• HV transmission lines is vital scheme for power system

• Teleprotection using HV transmission lines using PLC

• Lightning surges may harm HV transmission lines / even the electronic components

THE MALFUNCTION OF SENGGIRING-SINGKAWANG PLC MODULE

• Figure 3. PLC 1790/B Photo shoot about LED alarm occurred when the modules were malfunctioned


THE ALIM CARD (POWER SUPPLY MODULE) TROUBLESHOOTING

• Based on Switching Mode Power Supply (SMPS)• All of the power output level were off• Replacement of the oscillator Circuit (logic NOT)

– Made the output +_ 15V, +_ 5V, level appear

• Rewinding of the transformer– Made the -36 volts level appear

• The addition of fuse on every level


THE ALIM CARD (POWER SUPPLY MODULE) TROUBLESHOOTING

• Figure 5 Basic switched mode power supply block diagram [6]


THE 20 WATTS HFPA MODULE TROUBLESHOOTING

• High Frequency Power Amplifier• Based on Differential Amplifier [7]• Examination on every components : Some transistor

were on leakage current between C-E• Replacement on substitute component of D44H11• PLC test on site : only success 2 minutes• The Breakdown of 3 Amperes fuse on -36 Volts SMPS :

the circuit still on damaged condition



• Figure 6. HFPA module block diagram [3]



• The creation of schematic and undergo simulation , find the operating currents : about 0.34 amperes

• Replacement on identical component of all MPQ2222, 2N2219A, D44H11 transistors

• Trial on site• Success. Alarm LED was off.



• Figure 7 Electronic Schematic Simulator of 20Watts HFPA using Proteus ISIS


RESULT

• Power Supply Module problems : MOSFET, NOT logic, winding of transformer

• HFPA Module problems : MPQ2222 2N2219A, D44H11• Addition of Power Supply Fuse (3 Ampere)


CONCLUSION

• Troubleshooting with trial and errors success• Trial and Error take a consideration of Operating Current• If The Operating Current goes far above the simulation, it

means there is still any breakdown• The internal fuse addition of every output voltage level is

a last attempt of electronic components protection
