HDE RM-100 – Phase Rotation Meter

Description HDE RM-100 Phase Rotation Meter

The PRM-100 Phase Rotation Meter is used to determine which is the leading phase of any two phases of a three-phase conductor system. The PRM is a dual-range, 0-5kV and 0-15kV, device that can be used as high as 45kV when optional resistor sticks(R-45) are added. It consists of two sticks with a connecting cord and ground lead.

Phase rotation is determined by taking readings on the two phases, first in one direction, then the other. The meter will indicate which phase is leading and which is lagging. The PRM-100 can be used in overhead applications with the included probes, or underground by adding the appropriate underground probes for your application.

PRM-100 – Triple range: 0-5kV, 5-15kV and 15-45kV with optional accessory R-45 add-on resistor sticks

• This meter does not measure voltage.
• Determine phase rotation on systems up to 5kV with the selector switch set for LO range and without the add-on resistor sticks.
• Determine phase rotation on systems up to 15kV with the selector switch set for HI range and without the add-on resistor sticks.
• Determine phase rotation on systems up to 45kV with the selector switch set for HI range and with the optional add-on resistor sticks installed, one on each meter stick.
