1. Buzzer High noise level buzzer LEDs High bright low current LEDs Battery Holder Buzzer Rotary Selector Battery Holder 4 Preparation for Use When unpacked the tester should be inspected for any visible signs of damage and the preliminary checks described in the user manual should be performed to ensure that itis operating correctly Ifthere is any sign of damage or if the instrument does not operate correctly return it to your nearest supplier This instrument is powered by three C type batteries Checking And Proofing The Tester Switch the sensitivity to SELF TEST The buzzer of the Hi Prox should beep and the LEDs should light This indicates that the Hi Prox is operational Verify the working of this unit by selecting 240Vac and place the dome against a low voltage live conductor or rub the dome with a cloth or against an item of clothing as this generates a static DC which triggers the detection of circuit The light and beeper should go on as if alive wire is being approached Approaching the dome neara computer screen or a TV screen not liquid crystal display type should also trigger the tester while on the 240V selection 5 Typical Uses e Identify and check live cables e Check and detect live high voltage cables using extension hot stick e Find fault in flexible cables e Check earth equipment e Service neon lighting e Trace live wires e Check high frequency radiation2. e Detect residual or induced voltages Broken Wires In Cables Faults in damaged flexible cables are found by applying low voltage to each conductor Earthing the remainder the wires that do not need to be traced Do not earth the live wire so that they can be detected by the Hi Prox and moving the tester along the cable until the change in condition is obtained Flexible cables as used in mining and building industries are readily repairable when the break in the cable is located 6 High Voltage Testing The rotary switch attenuator is used to identify and differentiate various HV live cables The tester must be used in conjunction with along and insulating rod when measuring high voltage kV Non Contact Itis advised that the tester should never come into contact with cables kV as this tester is merely a non contactAC Proximity tester Limitations On The Hi Prox It is recommended that this tester is not used in HV yards of mixed voltages In the presence of mixed voltages the tester can become unreliable Problems can arise when the tertiary circuit of a 275 133 11kV transformer is tested The electric field of the HV and MV bus bars can trigger the detector when it is about 3m above the ground This is common with most of the electric field voltage detectors Users should be aware of it The tester can pick up adjacent circuit to the one being tested and Indicates the wrong information to the user 7 L

6. ed CMOS logical level change The self test inserts a voltage on the sensor plate just like if the sensor would pick up a voltage The Hi Prox allows identification of AC voltages from 220Vac to 275kVac The enclosure is made out of industrial grade polyurethane The enclosure can be attached to a link stick The small cylinder part of the Hi Prox fits into most link stick adaptors 2 Low Voltage Testing The Hi Prox works by proximity Physical contact with electrical conductors is not necessary when testing for live lines Its sensor senses the radiated field which surrounds live conductors It is recommended not to touch high voltage wires with the Hi Prox Radiated field strength increases with voltage and decreases quickly with distance or earth shielding The radiated field from a cable of closely bunched conductors supplied by three phase power tends to cancel See Limitations of the Hi Prox on page 9 Detecting distance of a 250Vac single live wire is about 10 cm and with a bunched neutral and earth cable as seenina flexible cable the distance is reduced to 5 cm 3 Front Panel Layout OFF Turn the pick up sensor off Self Test Check if the entire circuitry is working 240Vac 240Vac selection 3 3kV 3 3kVac selection 6 6kV 6 6kVac selection 11kV 11kVac selection 22kV 22kVac selection 33kV 33kVac selection 66kV 66kVac selection 132kV 132kVac selection 275kV 275kVac selection
7. instrument e The Hi Prox must never be in physical contact with any conductor higher than 1kV This is a proximity detector not a detector which works by contact e Always use a fiber glass rod or any authorized stick e Ahigh voltage test is carried out with the tester attached to an operating stick sometimes called links stick e Verify the rotary switch setting before measuring Make sure it is on the correct setting for your application e Always check that the Hi Prox is working before and after the test e Do not touch any exposed wiring connections or other live parts of an electrical circuit This instrument should only be used by a competent suitably trained person who understands this test procedure fully Personnel working with high voltage should be trained regularly 1 General Description The Hi Prox consists of an internal pickup sensor plate a rotary switch as sensitivity selector a sound annunciator high pitch high power buzzer a visual indicator high bright LEDs and three C size batteries The Hi Prox detects AC voltages using the sensor plate The sensor plate collects part of the radiated electric field V M The electric field is seen by the internal circuitry and triggers the input ofa CMOS integrated circuit The integrated circuit charges a capacitor via a diode Once that capacitor reaches a certain level the buzzerand LEDs annunciator are turned ON The trigger level is fix
