®HIGH VOLTAGE PROXIMITY DETECTOR
Model 275 HP (Upto 275KV) / 500 HP (Upto 500KV)
The 275HP / 500HP is a HIGH VOLTAGE proximity detector. 275HP has eight voltage detection settings from 240Vac to 275KVac. & 500HP
has 10 Voltage detection settings from 240V to 500KV. The 275HP / 500HPconsists of an internal pickup sensor plate, a sensitivity selector,
a visual and a sound annunciator. With the 275HP / 500HP physical contact with electrical conductors is not necessary when testing for live
lines. This tester works by proximity.
Checking or proofing the tester is easy. Switch the sensitivity to 240V AC 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 a live wire is being approached.
Approaching the dome near a computer screen or a TV screen (not liquid crystal display type) should also trigger the tester while on 240V selection.
Its sensor senses the radiated field which surrounds live conductors. Radiated field strength increases with voltage & 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 use” paragraph). Detecting distance of a 250Vac single live wire is approximately 10cm. With a bunched neutral and
earth cable, as in a flexible cable, the distance is reduced to 5cm.
Some of the typical users are : identify and check live cables; find fault in flexible cables; check earth equipment; service neon lightning;
trace live wires; check high frequency radiation ; detect residual or induced voltages. For example, faults in damaged flexible cables are
found by applying low voltage to each conductor. Earthing the remainder and moving the tester along the cable until the change in condition
is obtained. (Flexible cables which are used in mining and building industries, are readily repairable when the break in the cable is located.)
When using for high voltage, the rotary switch (attenuator) is used to identify and differentiate various HV live cables. The tester must be
used in conjunction with a long and insulating rod when measuring high voltage (KV). However, the 275 HP / 500HP is a non contact
tester and it is advised that the tester should never come in to contact with cables (KV) as this tester is merely a non-contactAC proximity
tester.

LIMITATIONS OF USE :
It is recommended that the 275HP / 500HPis 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
above 3m above the ground. This is common with most of the electric field voltage detectors, and the users should be aware of it. The tester can pick up adjacent
circuit to the one being tested and indicate the wrong information to the user.

The distance for detection of the voltage depends upon the
range selected & actual Voltage of the conductor.
e.g. If the range selected is PC11KV, the minimum distance for
detection of the PC11KV voltage is 22cm. But if the range
selected is PC22KV, you need to be closer (14cm) to detect
the PC11KV conductor.

Safety Rules
The 275HP Hi-Prox has been designed with safety in mind.
However, no design can completely protect against
incorrect use.
Electrical circuits are dangerous and lethal through
lack of caution or poor safety practice. The following
rules should reduce the danger:
Read the user manual carefully and completely before
using the tester. Fully understand the instructions before
using this product. Follow the instructions for every test.
Take all the necessary precautions. Do not exceed the
limits of this instrument.
The 275HP 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.
Always use a fiber glass rod or any authorized stick.
A high voltage test is carried out with the tester attached to
an operating stick, sometimes called “links stick”.
Verify the rotary switch setting before measuring. Make
sure it is on the correct setting for your application.
Always check that the 275HP Hi-Prox is working before
and after the test.
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.

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 a long and insulating rod when
measuring high voltage (kV).
Non-Contact
It is advised that the tester should never come into contact
with cables (kV) as this tester is merely a non-contact AC
proximity tester.
Limitations On The 275HP 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.

General Description
The 275HP 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 275HP 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 of a CMOS integrated circuit. The
integrated circuit charges a capacitor via a diode. Once that
capacitor reaches a certain level, the buzzer and LEDs
annunciator are turned “ON”.
The trigger level is fixed (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 275HP 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 275HP Hi-Prox fits into most link stick adaptors.
04

®
Low Voltage Testing
The 275HP 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 275HP 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 275HP 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 seen in a
flexible cable, the distance is reduced to 5 cm.
05
®
Typical Uses
Identify and check live cables
Check and detect live high voltage cables (using
extension hot stick)
Find fault in flexible cables
Check earth equipment
Service neon lighting
Trace live wires
Check high frequency radiation
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 275HP 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).
08

®
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 it is operating correctly. If there 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
275HP Hi-Prox should beep and the LEDs should light.
This indicates that the 275HP 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 a live wire is being
approached.
Approaching the dome near a
computer screen or a TV screen
(not liquid crystal display type)
should also trigger the tester
while on the 240V selection.
