What
is an effective or a root mean square value of an alternating current
and of an alternating voltage? |
|
What is average
power of an AC circuit? |
|
What
is the electric power in an electric circuit with a pure resistance? |
|
How can the
electric power of an electric circuit with resistance and inductance
be calculated? |
|
Why is a three-phase
alternating current used often for electric devices? |
|
What is bi-directional
power flow? |
|
Why does phase
difference occur? What is power factor? |
|
Why does waveform
get distorted? |
|
What does the
CT protector (M-System model CTM) that is installed onto the socket
of the transmitter do? |
| |
The display
of the current meter on our control panel differs from that of a
digital indicating tester. The current meter receives the signal
from a CT transmitter. Why does the difference occur? |
| |
What is the
two-wattmeter method that is suitable to unbalanced load in measurement
of three-phase power? |
|
Can we obtain
integrated power with a power transducer? |
|
We want to
measure active power in 3-phase/3-wire, balanced system, with single
current transformer, not two. |
|
Combination
of DCS with power management system |
|
What are the
input waveform requirements when using average sensing VS. RMS sensing
type current/voltage transducers? |
|
M-System's
Power Transducers have no earth ground connection terminal. Why
is this? |
|
I want to measure
electric power with a power transducer to provide a pulse output&.
Do you have a transducer which can correspond to the change of CT
or PT after installed and wired, and the pulse unit (Wh/pulse) of
which can be set on site? |
|
We are planning
to monitor AC current signal 0-5A from a current transformer (CT)
on a PC. Because the scanning time of PC is fast, we are looking
for a fast-response type Power Transducer to meet the feature of
this measurement target. |
|
Bidirectional
current transducer -- What is this transducer used for? How different
from normal AC current (CT) transducers such as model LCE? |
|
How to get
two pulse outputs for bidirenctional power? |
|
Why do we need
to mount a CT protector on plug-in CT transducers? |
|
How to determine
the VT input value for 3-phase/4-wire configuration for M-System's
watt transducers such as the model LTWT? |
|
We have just
integrated two equipment systems together. Now besides the instantaneous
power consumption of each system, we also need to monitor the aggregated
power consumption as well. Do you have any good advice for this? |
