(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-amme-

ter’s built-in, low-burden, toroid sensor.

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.

1. CT Precautions: In normal operation, a 5A current transformer’s secondary circuit

2. CT Connections and Grounding: Some applications require connecting one of the CT’s

3. Installation: CT’s must be installed in a manner that ensures no excessive stresses are

TECHNICAL NOTES

IMPORTANT! To ensure safe and reliable operation, Current Transformers and asso-

ciated 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 cir-

cuit is energized. Contact DATEL if you have any doubts regarding the installation

or operation of any of our ac-mains measurement instruments and accessories.

operates at a relatively low voltage due to its closed-loop, low burden conﬁguration

(essentially zero Ohms when used 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.

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.

applied to the primary conductor that passes through the CT or to the secondary circuit

and its associated instruments. Use plastic tie-wraps and/or other suitable non-conductive

restraining devices to secure the CT.
