Description

Tap sensor DP4 is designed to determine actual transformer tap on load. This sensor may be connected to the MZ- 2, MZ-3, MZ-4 type drives. Sensor DP4 is an electronic sensor of drive turn angle with a signal conversion circuit. It can be used instead of a resistive sensor. Sensor DP4 has several interfaces in order to transmit the drive turn angle. These are: interface RS-485 for the transformer tap data transfer to PCS or UP 25 OLTC Position Monitors in digital form via MODBUS protocol. “Current loop” analog current interface 4-20 A, 0-5 mA or 0-20 mA is designed for the transformer tap data transfer to UP 25 OLTC Position Monitors or PCS by additional transmitters.

Analog interface 0-5 V or 0-24 V is used for the transformer tap data transfer to UP 25 or PCS by additional transmitters. When using this interface, sensor DP4 can function as a resistive sensor of MZ-2, MZ-4, EM1, MR and ED-S drives, the sensor can be used to connect Siemens and ABB transformer protection and control automatics to drives..
