2. 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

6. 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

7. THE ALIM CARD (POWER SUPPLY
MODULE) TROUBLESHOOTING
• Figure 5 Basic switched mode power supply block

8. 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

10. THE 20 WATTS HFPA MODULE
TROUBLESHOOTING
• 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.

11. THE 20 WATTS HFPA MODULE
TROUBLESHOOTING
• Figure 7 Electronic Schematic Simulator of 20Watts
HFPA using Proteus ISIS

12. RESULT
• Power Supply Module problems : MOSFET, NOT logic,
winding of transformer
• HFPA Module problems : MPQ2222 2N2219A, D44H11
• Addition of Power Supply Fuse (3 Ampere)

13. 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
