GENERAL DESCRIPTION
The phase rotation meter is constructed with epoxy encapsulated high voltage resistors, a
connecting cord, a ground lead and a meter display. The major elements are shown here:
The high voltage resistors limit the current through the connecting cord to a maximum
of about one milliamp. Although the connecting cord is insulated for voltage up to 10kV,
it should always be kept free and clear from you, ground and any other conductors.
WARNING: The phase rotation meter has a range switch and requires add-on resistor
sticks for higher voltage ranges. Always completely remove the phase rotation meter from
the live circuit before changing the range switch position or adding or removing add-on
resistor sticks. Always use add-on resistor sticks in pairs, one on each stick.

PHASE ROTATION METER
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.

OPERATING INSTRUCTIONS
Pre-Use Inspection
WARNING: Before using the instrument be sure to test and inspect the equipment
to insure that it is functioning properly and is in safe, working condition. Failure to do
so may cause serious injury or death and may result in erroneous test measurements.
Before taking any reading, test and inspect the phase rotation meter as follows:
1) Make certain the instrument is clean, dry and waxed to a clear shiny surface.
2) Inspect the cord for cracked insulation.
3) Be sure that you are using hotsticks of the appropriate length, and examine each
hotstick to insure that it is clean, dry and waxed to a clear shiny surface.
4) Attach the appropriate probes for overhead or underground applications
(see page 6) and that the probes are properly installed and tightened.
5) Confirm the range switch is in the proper position.
6) Install add-on resistor sticks if necessary for the range being tested.
7) Test the phase rotation meter with a proof tester such as the HD Electric
PT-5000B (see page 6).

OPERATING INSTRUCTIONS continued
Phasing Measurements
We recommend that two person crews take the readings. Since the operation is occurring
near two energized conductors, the use of two person crews allows each person to operate
one stick and maintain high safety standards.
In order to take a reading, each probe must contact an energized line. Be sure that only
those probes intended for the particular application are used (see page 6). Always keep
the connecting cord free and clear of energized phases and ground.
The phase rotation meter requires three connections for proper operation. Always connect
the ground lead first and only to a known good ground. After testing is complete, be
certain to remove and isolate the main contact probes from all voltage sources prior
to disconnecting the ground lead.
Take the Readings
To determine which of the two phases is leading or lagging, two separate readings
are required.
READING 1: Place one probe (resistor stick) on each of the two phases being
tested and take a reading.
READING 2: Reverse the probes (resistor sticks) so that they contact the same
two phases but in the opposite direction, and take a reading.
FOR EXAMPLE: If in Reading 1 the probe with the meter on it was contacting Phase A
and the probe with the junction box was contacting Phase B, then
reverse them so the probe with the meter on it contacts Phase B and
the probe with the junction box contacts Phase A.
Determining the Results
The resistor stick with the meter on it will show a higher indication when it is in contact
with the leading phase. The meter indicates relative phase rotation. The resistor stick with
the meter on the leading phase will indicate a reading of up to 100 at the maximum
voltage for the range selected. The resistor stick with the meter on the lagging phase
will indicate about 60% of the leading phase reading
For three phases there are three pairs of phases, so any two pairs should
be tested as outlined above. For example, with three Phases A, B and C:
1. Test Phases A and B. A is determined to be leading B.
2. Test Phases A and C. C is determined to be leading A.
Now, A leads B from Step 1. C leads A from Step 2. Therefore, the rotation is
C-A-B. This can also be written as A-B-C. This can be verified by testing the
third pair of phases. Test Phases B and C. B is determined to be leading C.

PROBES AND ACCESSORIES
WARNING: ALWAYS use probes appropriate to your application.
NEVER use overhead probes in underground applications. Failure
to use the correct probe can result in arcing or electrical contact
and may cause serious injury or death. If you are not trained in
the particular operation or are not sure about the appropriate
probe for your application DO NOT PROCEED.

PROOF TESTER
The PT-5000B Proof Tester will produce 5kVDC at the test
leads to confirm proper operation of the phase rotation
meter. The PT-5000B operates from one 9V alkaline battery
and produces approximately 5kVDC at the connecting
leads. To use:
1) Connect both tester leads to the phase rotation meter
probes. Isolate the ground lead from ground or any
other conductor and do not touch it during the test.
2) Press and hold both TEST buttons.
3) Confirm a good battery by checking the red light on the Tester.
If the red light does not come on, replace the battery with a 9V alkaline only.
4) Verify the phase rotation meter reads approximately 5kV.
5) Release the TEST buttons and disconnect the Tester from the phase rotation meter.
WARNING: Do not use the phase rotation meter if proper operation is not confirmed.
WARNING: Do not use this tester except as directed. Do not use to test equipment
other than the phase rotation meter. Do not apply to energized circuits or equipment.
Refer all servicing to the factory. Failure to follow these instructions may lead to
electric shock, severe injury or death.

CARE AND MAINTENANCE
Periodic regular maintenance is required to keep the phase rotation meter in proper
operating condition. Keep the phase rotation meter clean and dry and always store
it in its case. The fiberglass sticks should be kept clean and free of dirt, contamination
and marking. Examine the cord for cracking or other damage prior to each use.
Although we don’t specify a calibration cycle, we recommend you test, measure and
calibrate your instrument annually. The Calibration and Maintenance Log can be used
to record these events. Contact HD Electric Company for details.
