Connecting to a Potential Transformer
Safety
Precautions
Follow the safety precautions listed on page E-3 when making all potential transformer
connections.
NOTE
Potential Transformers are not manufactured by Dranetz and are discussed here for
informational purposes only.
Definition
A potential transformer (PT), also referred to as a voltage instrument transformer,
provides the necessary step-down ratio to reduce the high voltage of circuits above
1000 Vrms to a level for safe measurement. A PT also provides isolation and proper
connections for instrument attachment.
Connections
PTs are usually fixed in position and require that the voltage probe(s) be connected to
their terminal connections.
WARNING
Refer to the manufacturer’s instructions, related to the PT, for exact information
for probe connection for voltage monitoring. Do not exceed 1000 Vrms input to the
HDPQ Xplorer voltage inputs.
ADVERTENCIA
Consulte las instrucciones del fabricante referentes a TP (transformador
potencial), para la información exacta de la conexión de sonda a fin de monitorear
el voltaje. No supere la entrada de 1000 Vrms a las entradas de voltaje de HDPQ
Xplorer.
AVERTISSEMENT
Se reporter aux instructions du fabricant relatives au transformateur de tension
(Potential Transformer - PT) pour obtenir les renseignements exacts sur la
connexion de sonde utilisée pour la surveillance du courant. Ne pas dépasser
l’entrée de tension efficace de 1000 RMS dans les entrées de tension de HDPQ
Xplorer volts.
WARNUNG
Genaue Informationen zur Meßfühlerverbindung für die
Spannungsüberwachung entnehmen Sie bitte den Anleitungen des Herstellers
(siehe Spannungsteilertransformator). Die Eingangsspannung von 1000 V
(Effektivwert) in die HDPQ Xplorer Spannungseingänge sollte nicht
überschritten werden.
