High Voltage Standard / V0 - DRAFT 2025-03-21
The participants shall:
Work in small groups to apply installed and portable voltage detection equipment following standards to verify absence of voltage.
Use instructions, manuals or guidance documents to evaluate system response and visual indications of voltage using primary and additional methods.
ELEMENT 12.3 - PROVE - TEST - PROVE / HOT - COLD - HOLD
To achieve the lesson learning objectives, the participants can:
109) Perform the 'Prove-Test-Prove' method to verify absence of voltage (Skills, intermediate level)
The instructor shall:
Explain the principles behind the 'Prove-Test-Prove' method:
a.
its role in HV safety
b. the importance of verifying test equipment functionality before and after use
Conduct a demonstration of the PTP method using a calibrated HV Voltage Detector:
a.
emphasising the procedural steps.
b.
highlight potential errors and risks such as:
b.i using unverified test instruments
b.ii failing to check all phases
b.iii misinterpreting test results.
Lead participants in a scenario-based fault simulation to test participants’ ability to correctly apply the method. Introduce realistic fault conditions such as:
a.
residual charge
b.
induced voltage
c.
incorrect earthing
