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 / 500HP consists 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-contact AC proximity
tester.

LIMITATIONS OF USE :
It is recommended that the 275HP / 500HP 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
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.
