TMRVI ProductNo more squinting to read the voltage from the end of the hot stick – or relaying information to the crew on the ground. The new CHANCE® Transmission Multi-Range Voltage Indicator® (TMRVI), lets your entire team accurately monitor transmission voltages on a mobile device or Apple Watch using the free MRVI app with an easy-to-read interface.

The TMRVI (model number PSC4033955) is a portable tool used to confirm whether an AC (Alternating Current) Transmission high voltage power circuit is energized, de-energized or has induced voltage prior to performing grounded maintenance. The instrument has been specifically designed to work with Transmission voltages (69kV through 765kV) and must be used with the appropriate length hot sticks per OSHA and company policy. It also provides the user the ability to observe lower voltages that may be present due to induction or storm emergency situations.

Providing field practicality over using a phasing set, readings from the TMRVI represent the class of voltage that is present on the line. The TMRVI 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 TMRVI is used as a secondary means to confirm the condition of a circuit after principle work procedures such as visible open gaps, dispatcher hold orders, and apparatus tag-outs have rendered the circuit de-energized. It can be used on overhead and underground systems with proper adapters and hot sticks.

This lightweight unit has many great features and benefits including:
  • Stepper motor technology displaying the approximate voltage class via its illuminated pointer
  • Hold feature
  • Audible alarms
  • Battery drawer for simple battery replacement
  • Power-saving sleep mode (auto-off)
  • Bluetooth technology for connection with mobile devices and Apple Watch

This smart meter is a must have for all linemen!
