Figure 3.95 — CT Position for Single-Phase Heaters
Three-phase Heaters
When a 3-phase power supply is used, regardless of the types of connecting
lines, two current transformers (CTs) are required to detect heater burnout and
HS.
1. For Delta connecting power lines:
Refer to the following diagram for
CT installation positions.
Note:
Heater voltage fluctuations are not considered here. Take this into
account when setting the detection current.

2. For Star (Y) connecting power lines:
Refer to the following diagram
for CT installation positions.
Note:
Heater voltage fluctuations are not considered here. Take this into
account when setting the detection current.
