Page 5: Introduction
The 275HVD Non-Contact High Voltage Detector must never be in physical contact with any conductor. This is a proximity detector, not a detector which works by contact. • Tests must only be carried out with the 275HVD attached to an approved insulated fiberglass rod or Hot Stick. • Always use an authorized fiberglass (or equivalent) rod or Hot Stick appropriately rated for the voltage with which you are working. -

Save the damaged packing container to substantiate your claim. Do not use an instrument that appears to be damaged. Ordering Information Non-Contact High Voltage Detector Model 275HVD ..Cat. #2131.12 Includes three 1.5V C-cell batteries, shotgun adapter, carrying case, and user manual. -
Page 7: Product Features
Always install proper grounding devices before working. Failure to do so may result in serious injury or death. Description The Non-Contact High Voltage Detector Model 275HVD is a high voltage detector by proximity. It is not designed to enter into contact with conductors. -
Page 8: Typical Uses (Always Use A Hot Stick)
(buried cables are often shielded) or shielded samples and the 275HVD has lower sensitivity on cables with concentric neutrals. It is not recommended to use the 275HVD on shielded cables or shielded samples. Use extreme care on cables with concentric neutrals (use a low setting). -

Page 11: Detection Levels
As a general rule, in a “clean” environ- ment, the 275HVD will trigger @ 45 to 65% of the voltage range at 4"/10cm, and detected the selected voltage setting at 8 to 12" (20 to 30cm). - Page 12 29" - 75cm 33kV 41" - 105cm SETTING VOLTAGE DISTANCE 11kV 22kV 13" - 35cm 11kV 33kV 16" - 42cm SETTING VOLTAGE DISTANCE 22kV 33kV 14" - 36cm Non-Contact, High Voltage Detector 275HVD GlobalTestSupply www. .com uality Products Online at: sales@GlobalTestSupp...

Page 13: Operation
• Electrical Field sensitivity is reduced when the 275HVD is used close to grounding points. • The Model 275HVD will work on cables with a concentric neutral. • The Model 275HVD will not work on shielded cables. -

LEDs should light up. This indicates that the sensor is operational and the battery functional. Perform the following steps to ensure that the 275HVD detects volt- age on a known live conductor. •... -
Page 15: Low Voltage Testing
The user may also consider using lower settings to check for lower voltages on a con- ductor. With the 275HVD at the end of a hot stick, move towards the live conduc- tor until its warnings are triggered. Low Voltage Testing See Warning on Page 5 &... -
Page 16: Faults (Open) In Cables
See Warning on Page 5 & 6 Faults in certain flexible cables can be detected with the 275HVD. If the cable is still energized, set the 275HVD sensitivity so that it triggers, then move the 275HVD along the cable until a change in condition is obtained. An audible tone and LED should be on when the sensor is on the supply side of the open and will turn off when on the other side. - Page 17 GlobalTestSupply www. .com uality Products Online at: sales@GlobalTestSupp...
