In electrical work, even after power is turned off, equipment may still hold dangerous leftover electricity. This is called residual charge, and it can cause shock or damage if not handled correctly. A static discharge stick is the tool used to safely release that charge before any repair or inspection.
This guide will show you how to use a static discharge stick step by step.
What Is a Static Discharge Stick?
A static discharge stick (also called a discharge hook) is a safety tool used to remove static electricity from equipment like:
Capacitors
Overhead lines
Switchgear
Busbars
It is made of an insulated pole, a metal hook, and a ground wire. The wire connects the stick to a safe ground so that electricity can flow out safely.
When Should You Use It?
Before working on high-voltage or medium-voltage equipment
When power is already turned off, but equipment might still be charged
Before touching capacitors, transformers, or busbars
Step-by-Step: How to Use a Static Discharge Stick
1. Check the Tool Before Use
Look for any damage on the stick, hook, or cable
Make sure the grounding wire is tight and secure
Clean the tool if it’s dirty or wet
2. Connect the Ground Wire
First, connect the crocodile clamp on the ground wire to a clean, metal grounding point
This point must be connected to the earth (ground system)
3. Extend the Stick
Hold the insulated handle
Extend the rod carefully toward the charged equipment
Stay outside the minimum approach distance for safety
4. Touch the Equipment
Gently place the hook onto the metal part of the equipment
Hold it there for a few seconds to let any charge flow out
5. Remove the Stick
After a few seconds, remove the hook
Retract the stick and keep it clean
Safety Tips
Never use the stick as a grounding rod for live circuits
Always follow your company’s safety rules and lockout procedures
Keep the tool dry and clean for best performance
Replace the stick if the insulation is damaged
