Guide to Warnings within Manual

The following is a list of warnings used within this manual and should be read in their entirety to ensure safe practices.

DANGER

A DANGER refers to operating procedures, techniques, etc., that, if not followed carefully could RESULT IN DEATH.

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.

WARNING

Always use an appropriate length insulated Hot Stick even when wearing rubber gloves. Contact with the universal coupling or other parts, even with rubber gloves, will cause erroneous voltage indication. Always use with a universal pole to maintain its calibration.

CORRECT USE INCORRECT USE

WARNING

Before and after each use, always test the unit on a known energized voltage source or with the Voltage Indicator Tester to verify proper operation.

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

CAUTION

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.

Function and Design Overview

The CHANCE® Multi-Range Voltage Indicator® (MRVI), model number PSC4033955, is a portable tool used to conﬁrm whether an AC (Alternating Current) Transmission high voltage power circuit is energized or de-energized prior to performing maintenance. The instrument has been speciﬁcally designed to work with Transmission voltages (69 kV through 765 kV). It also provides the user the ability to observe lower voltages that may be present due to induction or storm emergency situations. It provides ﬁeld practicality over the two points of contact measurement method. Readings from the MRVI represent the class of voltage that is present on the line. The MRVI is designed to determine approximate Phase-to-Phase and Phase-to-Ground nominal voltage. This unit is a direct contact electric ﬁeld intensity indicator.

The MRVI is used as a secondary means to conﬁrm the condition of a circuit after principal work procedures such as visible open gaps, dispatcher hold orders, and apparatus tag-outs have rendered the circuit de-energized.

For Distribution voltages, including Capacitive Test Point, we would recommend utilizing the Distribution MRVI, model PSC4033710, which is speciﬁcally designed for those ranges.

NOTICE

This device is an AC (alternating current/alternating voltage) only indicator; do not use it to detect DC (direct current/non-alternating voltage).

WARNING

Before and after each use, always test the unit on a known energized voltage source or with the Voltage Indicator Tester to verify proper operation.

Accuracy

This instrument is not a voltmeter; hence, the manufacturer claims no speciﬁc accuracy and therefore no speciﬁc accuracy is to be assumed by the user. Readings will vary with the ﬁeld intensity, determined by a great variety of ﬁeld conditions including proximity, size, and orientation of all system components in the vicinity, both energized and grounded. Erroneous readings may result from being placed near other energized conductor, sources, or grounds. To avoid such ﬁeld distortions: keep the unit as far away as practical from all system components other than the speciﬁc conductor being tested.
