OLTC Controller UP-100

OLTC Controllers

Description

On-load tap changer (OLTC) controllers are the main part of the power equipment monitoring and control system. They continuously control status of switching devices of transformers with smoothly or sharply changing loads at 35-750 kV substations. Controllers UP100 operates with any type of sensors of OLTC drive position without additional adapters. Additional adapters are not needed. Exploitation of controllers are comfortable for substation personnel due to availability of separate screens displaying information on OLCT drive’s taps and information on transformer’s parameters. They are connected to transformers with nominal secondary voltage 100V and nominal secondary current 1A or 5A.
