Equipment for Checking Electrical Leakage

Electrical leakage detection equipment is crucial for preventing potential hazards from current leakage. Here are the main tools used to check for electrical leakage:

1. Test Pen (Voltage Tester Screwdriver):

   This basic tool is used to check if electricity is flowing through a wire. When the tip of the screwdriver touches the wire, an indicator light on the tool will illuminate if current is present.

   
   

2. Multimeter:

   This device measures voltage, current, and resistance. To detect electrical leakage, set the multimeter to voltage or resistance mode to check for stray current from wires or electrical appliances.

   
   

3. Earth Leakage Circuit Breaker (ELCB):

   Installed in electrical systems to prevent leakage, this device automatically cuts off power when it detects leakage, thus preventing potential hazards.

   
   

4. Non-contact Voltage Tester:

   This tool detects voltage in wires without direct contact. It can be used to check for leakage in areas like outlets, wires, or electrical appliances.

   
   

5. Clamp Meter:

   Used to measure current without disconnecting wires, this tool can detect leakage by measuring current on the grounding wire. If current is detected, it may indicate leakage.

   
   

The choice of equipment should depend on the specific characteristics of the electrical system being inspected.
