WARNING
A WARNING refers to operating procedures, techniques, etc., that, if not
followed carefully, could RESULT IN INJURIES OR DEATH.
CAUTION
A CAUTION refers to operating procedures, techniques, etc., that, if not
followed carefully, could RESULT IN DAMAGE TO EQUIPMENT or LOSS OF SERVICE to
customers.
NOTICE
A NOTICE refers to information that is considered important but not hazard
related.
Product Safety
WARNING
Do not allow the universal coupling or housing to become grounded in any way,
or to contact another phase, as this will cause erroneous voltage indication
and could cause severe personal injury or damage to equipment.
When used on higher voltages, observe additional working clearance for the
increased voltage from hands to line parts. Including Epoxiglas™ resistor
housings, universal fittings, meter, and cable.
WARNING
Always use with an appropriate length insulated hotstick even when wearing
rubber gloves. Contact with the universal coupling or other parts, even with
rubber gloves, will cause erroneous voltage indication. Do not engrave on
stick.
CORRECT USE
WARNING
Before and after each use, always test the unit on a known energized voltage
source or with an appropriate Voltage Indicator Tester.
DANGER
Minimum Approach Distances (MAD) should be adhered to at all times. For the
latest information and charts refer to the official OSHA website:
https://www.osha.gov
WARNING
The equipment covered in this manual must be used and serviced only by
competently trained personnel familiar with and following approved work and
safety practices. This equipment is for use by such personnel and this manual
is not intended as a substitute for adequate training and experience in safe
procedures for this type of equipment. These instructions neither cover all
details or situations in equipment use, nor do they provide for every possible
contingency to be encountered in relation to installation, operation, or
maintenance. Should additional information and details be desired or if
situations arise which are not covered adequately for the user’s purpose, the
specifics should be referred to Hubbell Power Systems.
Generic Components of the Phasing Meter
Function and Design Overview
The CHANCE ® Phasing Meters are portable devices which permit the checking of
AC voltages on distribution and transmission circuits from 1 kV to 161 kV for
the purpose of determining phase relationships and the approximate voltage
line-to-line or line-to-ground of the circuits. When used above 15 kV, extra
caution is required to maintain working clearance for the higher voltage.
The basic instrument, Model No. H18761, is designed for voltages up to 16 kV
read directly on the analog scale of the meter. High impedance resistance
units are encapsulated to protect them from mechanical damage and to prevent
moisture penetration or accumulation around the resistors. The remainder of
the handle is foam filled to prevent moisture accumulation. Between the two
resistor units there is a milliammeter and a connecting cable with 15 kV
insulation. The resistors limit current values to less than 1.25 milliamperes
at maximum voltage rating across the probes. Capacitive current to ground
through the cable insulation depends upon area of ground contact. For example,
a 4-inch contact pad induced a capacitive current of less than 40 micro-
amperes (0.04 milliamperes) at full voltage. This is below perception levels.
Current to ground resulting from cable insulation failure or damage is limited
to less than 1.5 milliamperes by the resistors.
Extension Resistors
Extension Resistor Sticks are available to increase the voltage range above
the instrument’s base voltage. The Extension Resistor Sticks are installed
with one on the meter stick and one on the reel stick. When installed, the
scale of the meter will be changed by a factor determined by which Extension
Resistors are used. The space surrounding these resistors is also encapsulated
for mechanical and moisture protection.
For voltages above 16 kV up to 48 kV, add one pair of H18764 Extension
Resistors. For voltages from 48 kV to 80 kV, add one pair of H18762 Extension
Resistors. An alternative application for voltages from 48 kV to 80 kV is to
use two pairs of H18764 Extension Resistors, installed with two on the meter
stick and two on the reel stick. NOTE: Extension Resistors are only for use on
16 kV maximum Phasing Meters.
Overhead Operation
The Phasing Meter is equipped with a cable reel on which the cable between the
two housings is stored.
CAUTION
During high voltage testing, only use the length of cable necessary to
permit the contacts to reach between the points of measurement. Any remaining
cable length should be kept wound on the reel.
There are two reasons for this:
- Cable insulation is limited to 15 kV for light weight and ease of handling. This is adequate for momentary contact with ground of 15 kV conductors but damaged insulation may result in an uncomfortable shock if personal contact is made at a damaged area. At higher voltages, insulation puncture may result. KEEP CABLES FROM CONTACT WITH OTHER MATERIAL OR PERSONNEL.
- Meter indications will be affected and error introduced by the capacitance to ground between the cable and grounded structure, moist concrete, or the earth. Other conductors will also influence meter indications if the cable is allowed to touch or come in close proximity to these conductors. RESISTOR ENCLOSURE PORTION CAN PUNCTURE ABOVE 40 kV. KEEP THIS PORTION CLEAR OF CONDUCTORS, STRUCTURES, AND GROUNDS.
CAUTION
This tool is not intended for continuous contact application. Tests at full
voltage for 30 minutes produced no damage, although heating of resistors did
occur. Contact should be limited to the time required to note the meter
indication. To measure line-to-ground voltage, the section on which the meter
is mounted should preferably be used at the ground potential contact to
minimize stray capacitance influence on the meter. On line-to-line
measurements, contact is made to each phase conductor keeping connecting cable
away from other conductors, grounded or metal structures, and isolated from
contact with platforms or each contact. As noted before, this is to avoid
influence which may distort meter indications. In tying two energized 3-phase
feeders together where it is necessary to match phases, voltage measurements
must be made between a conductor of one circuit and each of the conductors of
the second circuit. This procedure is followed for each phase to avoid
connecting phases in reversed rotation. Re-check the third phase just before
making the final connection to assure proper phase relationship. With matched
phases one may expect the voltage indication to be near zero. More often a
voltage will be indicated due to phase shift at the open point in remotely
energized circuits and/or unequal voltage drop. Proper connections can readily
be determined by the meter indications. Preliminary phase-to-phase
measurements of each circuit are recommended to determine that proper voltages
are being connected.
CAUTION
In substations, bus and switchgear cubicles, or other crowded areas where
electrical fields are of greater intensity, extra precaution is recommended to
avoid disturbing influences affecting meter indications.
Underground Operation
When using the Phasing Meter on underground systems, the same basic rules and
procedures apply as with overhead, for example, maintaining proper working
clearances to all parts of the tool, keeping tool clean and dry, keeping cable
from contacting nergized or grounded surfaces, etc. However, there are some
additional considerations when using the tool on underground equipment.
DANGER
- When testing dead-front URD equipment, use an appropriate Bushing Adapter on the Bushing Well. On Capacitive Test Points, use the Straight Probe. Never use the Shepherd Hook on URD equipment.
- Use extreme caution when testing live-front URD equipment. Use applicable safe work practices and procedures. Do not use any Probe or Bushing Adapters on the Phasing Meter when testing live-front URD equipment. Only use a small hex head machine screw (1/4-20 X 3/8″long).

Maintenance
The CHANCE® Phasing Meters are electronic instruments and, if properly cared
for, will provide many years of trouble-free service. Keep all parts clean and
dry. Clean only with water or a mild soap & water solution. Do not use
chemical solvents. When using soap for cleaning, it is required to thoroughly
rinse all soap residue off the unit before placing back into service. Any
remaining soap residue may allow high voltage tracking especially in the
presence of high humidity and/or moisture. Do not use CHANCE® Moisture Eater
II wipes on any part of the tool as it will cause damage. We recommend that
every Phasing Meter be wiped clean and visually inspected for defects daily
and before each use. If any defect or contamination that could adversely
affect the proper operation, accuracy, or mechanical integrity of the tool is
suspected, the Phasing Meter shall be removed from service. Before placing
back into service, the Phasing Meter (including the stick portions) should be
properly repaired (if necessary), cleaned, inspected, and tested for full
operation. Do not engrave on stick or meter housing. Abuse or misuse will
damage the unit. Store in a dry location, do not drop, and protect from
jostling or impacts during storage, carrying, or use. Never straighten or
modify probes.
CAUTION
Be careful when handling the Phasing Meter. Do not drop or scratch the tool.
