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

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:

1. 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.
2. 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

1. 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.
2. 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.
