5. BOOMER Designs HIGH VOLTAGE DETECTORS GEW APPLICATION NOTE by Jacques Botte V2 00 WHY WHERE AND HOW TO USE THEM High Voltage Detectors are mostly used where personnel need to be informed of the presence of High Voltage in their proximity or on equipment near where work is going to be performed on High Voltage Detectors can be of different types Proximity Detectors detect voltage as you approach the source and Contact Detector only indicate when you make one or two contacts with the source In all cases High Voltage Detectors are only used to positively identify High Voltage pres ence but not their exact amplitude High Voltage Detectors are not to be used to confirm the absence of High Voltage 2 75HP A Proximity Detector is used to Warn the user of potentially deadly situation and possibly prevent serious Accident NYLON WATER RESISTANT The 275HP is a Portable and Battery Operated High Voltage Proximity Detector which detects the proximity of electromagnetic fields created by AC signals If you are very close to the source of an electromag netic field that field is bigger than if you were ata distance from the source As you go further away from that source the field progressively weakens Some source are higher than others That s why the 2 5HP has different settings When checking a high source the 275HP can be set to a higher setting if it was left on a lower setting t
6. gives enough energy to the 285HD to detect if high voltage is present and to power it s internal circuitry which will activate the warning LCD Briefly How does it work The 285HD collects the electric field around the cable on which it is mounted to supply it s internal circuitry and drive the flashing Red LCD Because of it s exceptionally low power consumption it does not require batteries Once enough power is collected from the electrical field the LCD flashes LIVE blank The level at which the LCD start flashing is the trigger level of the 285HD Why use the 285HD The 285HD is used to detect the presence of High Voltage AC on Cables or equipment conductors It s fixed permanently so that a report on the status on input or output of the equipment is visual and instantaneous There is no need to prepare bulky and expensive equipment when just a quick check is needed for example when you just need to know if a system is ON or a phase is energyzed Where to use it GEW The 285HD is used where personnel must be protected from high voltage or know the presence of high voltage on cables It is used on the primaries and secondaries of transformers on the input and output of High Voltage Contactors or fuses This simple device is utilized to give the LIVE status of the equipment but can t be utilized to check a non live status Personnel without the contact measuring equipment can report LIVE
7. he voltage could be detected from further away of that source The 275HP has a light and a buzzer which indicates the presence of voltage within proximity Briefly How does it work The 275HP has a sensor which sense the voltage When voltage is detected within proximity the 2 5HP sounds and light an alarm It has an attenuator rotary switch which draw more or less current from that field The lower the current the more sensitive it is When on a higher setting the 275HP needs more volts per meter V M to trigger the voltage proximity alarm circuitry So turning the rotary switch clockwise means that more V M is required to trigger the 275HP and vice versa The rotary switch is clearly marked with the system voltage settings Why use the 275HP The 275HP is used to detect the proximity of High Voltage AC without touching the conductors This is a safe and quick method to determine if High Voltage is present on Cables or equipment before proceeding with any work around such equipment This does not replace the contact test which guarantee that a system is or isn t live Where to use the 275HP The 2 75HP is used where personnel must be protected from high voltage or know the presence of high voltage This is used before and during proceeding with any work around suspected High Voltage cables or equipment How to use the 275HP The 275HP is utilized the following way First the 275HP s function switch is turned on the
