These commercial grade, UL & CSA recognized, “donut

style” AC current-transformers (CT) provide an isolated 0-5A

output that can be used with DATEL’s ACA5 Series of digital

ammeters. Installation is straightforward: simply pass the load-

carrying conductor through the 5A CT’s primary window, and

then route its secondary’s leads through the ACA5-ammeter’s

built-in, low-burden, toroid sensor.

All models feature rugged, fully insulated construction, allow-

ing continuous operation with primary voltages up to 600Vac,

at line frequencies from 50 to 400Hz. Fourteen models are

available to enable accurate measurements from 50A through

2000A. When combined with DATEL’s ACA5 Series ammeters,

secondary lead-extensions may be used for those applications

where the CT cannot be installed in the immediate vicinity of

the ammeter.

with DATEL’s ACA5 series ammeters). However, any CT can generate

potentially lethal voltages if its output current is suddenly interrupted.

For example, loose secondary connections can produce a condition

referred to as “inductive kick.” Inductive kick can generate extremely

high voltages across the open secondary connections.

Therefore, all connections made to a CT’s secondary leads must only

be performed with zero current flowing in the primary circuit. Never

operate a CT with its secondary circuit open and current flowing in

the primary.

2. CT Connections and Grounding:

Some applications require con-

necting one of the CT’s 5A output terminals to earth/chassis ground.

In the USA, consult the latest revision of the National Electrical Code

for more information.

After all mechanical assembly is completed, pass the 5A secondary

leads through the ACA5 ammeter’s built-in toroid, then connect the

two leads together as shown in Figure 1. For this connection, and

for connections involving lead extensions, pressure-style connectors

(commonly called “wire nuts”) are acceptable as long as they are rated

for the currents and voltages involved.

3. Installation:

CT’s must be installed in a manner that ensures no

excessive stresses are applied to the primary conductor that passes

through the CT or to the secondary circuit and its associated instru-

ments. Use plastic tie-wraps and/or other suitable non-conductive

restraining devices to secure the CT.

Basic Lightning Impulse Insulation Level (BIL): The insulation strength refer-

enced to the crest value of an impulse voltage-waveform which rises to a crest

value in 1.2 microseconds, then drops to 1⁄2 the crest value in 50 microseconds.

Tehnical Notes

IMPORTANT! To ensure safe and reliable operation, Current Trans-

formers and associated equipment must be installed and serviced

by qualified technical personnel. Never open the CT’s secondary

connections while the primary is energized. Open CT secondary

wiring can generate potentially lethal voltages when the primary

circuit is energized. Contact DATEL if you have any doubts

regarding the installation or operation of any of our ac-mains

measurement instruments and accessories.

1. CT Precautions:

In normal operation, a 5A current transformer’s

secondary circuit operates at a relatively low voltage due to its closed-

loop, low burden configuration (essentially zero Ohms when used
