The Voltstik is a distribution voltage voltmeter designed for lines and substations. These units are designed for use with a hotstick and universal chuck adapter. They are capable of measuring voltage phase to phase, phase to ground, and regulator tap settings.
This high impedance instrument is an excellent choice for solving multiple problems associated with operating a medium voltage system. Its key applications can be defined under three groups, safety confirmation, troubleshooting voltage problems, and phasing.
Safety Conformation The number one consideration in working with medium voltage is insuring a safe working environment. The Voltstik will measure the actual voltage leaking from a defective insulator. It will measure the buck to boost bushings on a tap regulator to make sure that the regulator is safe to bypass. It will also determine if a conductor is carrying induced voltage from another line.
Trouble shooting Voltage Problems The Voltstik gives the electrician the ability to measure the potential of any two points within the medium distribution system. Voltage drop along a line can be measured or a check of phase to ground voltage on the primary side of a voltage complaint can determine if the cause belongs to the utility or the customer.
Phasing The most common use for measuring voltage in a distribution system is measuring phase to phase. This in the past has been performed with a dedicated instrument called a "Phasing Set". The SensorLink Voltstik offers advantages to the traditional methods. The Voltstik has accuracy rating of ±2% while most phasing sets can only boast of reading the approximate voltage. The Voltstik has a digital readout while many of the other sets have an analog dial that is difficult to read. The Voltstik has a wide range of uses where the traditional phasing set is only used for phasing.
The Voltstik is available in three sizes 0-20kV, 0-30kV, and 0-40kV. The housing is made of urethane and built to operate in severe utility environments. They are resistant to shock, water repellent, and unsusceptible to flame. It also operates in a wide temperature environment. |
