Testing Devices Flashcards
600 volt tester features
- verifies transformer secondaries are de-energized
-tests the condition of circuits and panel boards
-determines an AC or DC voltage source
-locate trouble in low voltage installations
What should always be done before assuming a no voltage reading is accurate?
Check the voltage tester on a source known to be energized
Are wiggys designed for continuous use?
No, it will burn out the solenoid
What should always be worn when using a wiggy?
Low voltage gloves
When testing, verify it is the correct device for what 3 things?
Right job
Right voltage
Right working condition
Steps to use a wiggy
1 visually inspect the tester and check the known voltage
2 find or provide bare spots on the conductors for contact points
3 conduct the test. Do not stretch leads or scratch contact probes where a questionable or no voltage reading is obtained
4 recheck tester
Kioki 3129 phase rotation detector step 1
Connect Hioki 3129 to the 3 phase wires at customer’s switch or CT cabinet. Always connect phases as defined by the job requirements/work order
Kioki 3129 phase rotation detector step 2
On new installations check rotation by pressing the switch button.
If rotation is clockwise, then mark panel RWB 1-2-3 to show rotation
If rotation is counterclockwise, then mark panel RWB 3-2-1 to show rotation
On existing installations, match the rotation found on the switch or CT cabinet, it cannot be changed if it’s already established
