Connecting to an Isolated Current Transformer (ISO)

Low current monitoring devices made by Dranetz are called isolated current
Introduction
transformers or ISO boxes. The Dranetz ISO box has a 5 A current range.
The following safety precautions apply to ISO box connections in addition to those
Safety
precautions
safety precautions stated on page E-3.
• Never energize an ISO box with the secondary open.
• Never disconnect the secondary of an ISO box with primary energized.
Physical injury or equipment damage could result if ISO boxes are improperly
WARNING
connected. Do not connect an ISO box between two conductors which are at
different voltage potentials.
ADVERTENCIA Podrían producirse lesiones físicas o daños al equipo si se conectan indebidamente
las cajas del transformador aislado de corriente (ISO). No conecte una caja del
ISO entre dos conductores que tengan distintos potenciales de voltaje.
AVERTISSEMENT Une mauvaise connexion des transformateurs d'intensité isolés (ISO) peut
provoquer des blessures corporelles ou des dégâts matériels. Ne pas relier les
transformateurs ISO entre deux conducteurs de tensions différentes.
Falsch angeschlossene ISO-Kästen (Isolierte Stromumwandler) können zu

with an ac current source. In normal connections, where phasing of current and
voltages are important for power measurements, the X1 terminal is connected towards
the source input line.
