Why true-rms?
If you’re
measuring
non-linear
loads like
variable
frequency
drives, solid
state heater
drives, or
electronics,
you need a
true-rms tool
to get accurate
readings.
Average
responding meters will read low,
up to 30 or 40 percent low in some
cases. This application note explains
what true-rms is and when you need
it in your test tool.

Non-linear loads need a true-rms
Why true-rms?
Figure 1. One current—two readings. Which do you trust? The branch circuit above feeds a
non-linear load with distorted current. The true-rms clamp reads correctly but the average
responding clamp reads low by 32 percent.
Introduction
Troubleshooting the electrical
service feeding adjustable
speed motor loads can be diffi-
cult if you don’t have the right
tools. New solid state motor
drives and heating controls
often conduct non-sinusoidal
(distorted) current. In other
words, the current occurs in
short pulses rather than the
smooth sine wave drawn
by a standard induction motor.
The current wave shape can
have a drastic effect on a
current clamp reading.
types of current clamps
commonly available: “average
responding” and “true-rms.”
The average responding units
are widely used and are usually
Basically, there are two
lower cost. They give correct
readings for linear loads such
as standard induction motors,
resistance heaters, and incan-
descent lights. But when loads
are non-linear, containing
semiconductors, the average
responding meters typically
read low. Worst case non-
linear loads include small
adjustable speed drives (5 hp
or less) connected line to line
across two phases of a 480 V,
three-phase system, solid state
heater controls connected
single phase to 240 V, or
computers connected to 120 V.
When troubleshooting a branch
circuit that suffers from circuit
breaker tripping (or fuse blow-
ing), the cause of the trouble
Application Note
can usually be separated into
one of three categories:
1. Too much current.
2. Too much heat in the
3. Faulty circuit breaker
Your first instinct will probably
be to measure the current with
a current clamp while the load
is on. If the current is within
the circuit rating, you may be
tempted to replace the circuit
breaker.
