High Voltage Standard / V0 - DRAFT 2025-03-21
Engage in a discussion on factors affecting the hazards of HV systems, including electrocution and arcing risks
ELEMENT 3.6 - ENVIRONMENTAL CONDITIONS AFFECTING HV VERSUS LV
To achieve the lesson learning objectives, the participants can:
24) Explain environmental factors affecting HV systems such as humidity, temperature, soiling and altitude (Knowledge, intermediate level)
The instructor shall:
Illustrate and explain environmental conditions affecting HV versus LV:
a.
salt, dust, soiling, and the risk of
a.i
corrosion, faults, shorts
b.
moisture and humidity and the risk of
b.i corrosion, faults, shorts,
b.ii increased flash over risk,
b.iii higher conductivity / lowering of resistances
c.
Temperature, and the risk of
c.i
damage to equipment, insulation, and
c.ii fire
d.
Altitude, and the impact on
d.i conductivity and insulation resistances
The participants shall:
Discuss the difference in HV versus LV including the impact of the different environmental conditions
