kaitsemaandust
Kaitsemaandust is the Estonian term for protective grounding, a safety practice in electrical installations that connects exposed conductive parts to the earth in order to limit the risk of electric shock and to stabilize voltages during fault conditions.
The word combines kaitse (protection) and maandus (grounding). In technical documentation and standards, kaitsemaandust refers to
Principles and purpose include providing a low-impedance path to the earth, ensuring rapid disconnection of faulty
Application and standards: Kaitsemaandust is applied in most electrical installations, from households to industrial facilities. Design
Regulatory context: In Estonia, electrical safety is governed by national legislation and building codes, with oversight
Limitations and considerations: Soil resistivity, moisture, and corrosion influence earth performance; regular testing and maintenance are
