High Voltage Breakdown
Test is a test for Electric Strength of insulation
The High Voltage Breakdown test is carried out to verify
the electric strength of insulation.
The High Voltage
Breakdown test is carried out on domestic / hose hold electrical appliances
(Standard EN 60335-1), electrical equipment of machinery (Standard EN
60204-1), etc. Usually a voltage twice
the rated voltage or 1000V, whichever is higher is applied, for 1s. For electrical cables and conductors, the
voltage is 2000V and the duration is 15 minute. During the High Voltage
Breakdown test at this voltage, when applied for this duration, no breakdown
of the insulation should occur. |
