6. Power monitor wiring precautions

Fuse Fuse

This is an example with the UPM100, but the voltage input wiring is also the same on the PR300
and UPM101.
Selecting a fuse
If not using a VT, insert a fuse of 0.5–1.0 A into lines P1 and P3.
Setting the VT and CT ratios
What are the VT and CT ratios?
Generally, when measuring high voltage and high current transformer signals, you use a VT
(voltage transformer) and CT (current transformer). The ratio between the primary and secondary
voltage and current ratings are the VT and CT ratios. With these ratios, a power monitor can
convert the primary voltage and current of the VT and CT and display the electrical quantities.
VT ratio: VT primary/secondary voltage rating
Ex.: VT ratio = 6600 VAC/110 VAC = 60
CT ratio: CT primary/secondary current rating
Ex.: CT ratio = 500 AAC/5 AAC = 100
If not using a VT or CT, each ratio is 1.

CT load rating and wiring length
●CT load rating
For the rated load, use a value within the sum of the wiring loss between the CT and the device
connected to the secondary side, and the input loss to the device connected to the secondary
side. The load rating notation could be, for example, “0.5 VA, 2.5 VA.”
CT
CT rated load ≧wiring loss + input loss of device connected to the secondary side
To calculate wiring loss, see “Checking the wiring distance and material” and
“Detailed example (approximation using the CTW10).”
Wiring distance Connected device
Device input lossWiring loss
●Checking the wiring distance and material
The wiring loss increases in proportion with the wiring distance. The total wiring length is the
round trip distance.
Approximate wiring material resistance (ex.)
 Nominalcrosssection1.25mm=approx.18Ω/km
 Nominalcrosssection2.0mm=approx.10Ω/km
● Detailedexample(approximationusingtheCTW10)
CT: Primary/secondary rated current: 100 A/1A
CT load rating: 0.5 VA
Wiring distance: 15 m, input loss of device connected to secondary side: 0.2 VA
• When using wiring material of nominal cross section 1.25 mm2
 WiringresistanceR=18Ω/km×0.015km×2(roundtrip)=0.54Ω
 Wiringloss≈I2R = (second. rated current)2×wiringresistance=1×1×0.54=0.54VA
 Condition:CTratedload≥wiringloss+inputlossofdevicecnctd.tosecondaryside
   0.5≥0.54+0.2=0.74VA
This does not meet the condition.

TI 77C01H01-01EN Oct. 17, 2018-00
• When using wiring material of nominal cross section 2.00 mm2
 WiringresistanceR=10Ω/km×0.015km×2=0.3Ω
 Wiringloss≈I2R = (secondary rated current)2×wiringresistance=1×1×0.3=0.3VA
 Condition:CTratedload≥wiringloss+inputlossofdevicecnctd.tosecondaryside
   0.5≥0.3+0.2=0.5VA
This does meet the condition.
CT handling precautions
●CT inspection and maintenance precautions
Do not perform work while measuring lines are live. If the secondary side is open while CT
currentisowing,highvoltageoccursonthesecondaryside.Thiscancauseinsulationto
degrade, and if left as-is, can cause burning and accidents and is extremely dangerous.
When maintenance is complete, before turning on the power, you must check the CT’s
secondary side connection (short).
TheCTWseriesofxedwiretypecurrenttransformershavebuilt-inhazardousvoltage
suppressors that function when the secondary side is open. In the unlikely case that the
secondary side is released, it will prevent burns and accidents.
When there is abnormal UPM100 power monitor measured data
Q. Voltage and current measurements on the power monitor are correct, but power integration
either doesn’t occur, or there are small values. What should I check?
A. Check the active power.
If the active power turns negative or extremely small, check the points below. The active
power is negative when the power is regenerating.
Points to check (3 phase 3 wire)
(1) Is the CT installed in the correct orientation?
(2) Is the CT installed to the R and T phases?
(3) Is the R phase side of the CT connected to 1S and 1L, and the T phase side connected to
3S and SL? Also check the CT secondary side polarity (k, l).
(4) Are R, S, and T wired to P1, P2, and P3?
