OLTC Position Monitor UP2x series

OLTC Position Monitor UP2x series
Description

UP2x series

UP2x series designed for drives with resistive sensor:

• MZ-2, MZ-4;
• MR, EM and ED-S;
• SAV1-1600-245/ 245-013;
• PDP-1, PDP-4 with replacement of selsyn sensor by resistant sensor of drive position DP-2;
• PDP-5L and any other drives equipped by resistant sensors with number of taps not more than 99.

UP2 series devices have possibility to compensate electrical resistance of connecting wires and work in configuration mode when the transformer is turned-on and located in the fixed position on one tap.

Universal position monitor UP 25 has all available inputs and otputs integrated in one device. Such “single-device approach” ensures both indication of transformer step data on the control switchboard and transfer of such data to Process Control Systems (PCS) and other automatization systems.

The device can be easily set up for different sensor types; even if you change your drive unit it is not necessary to change the indicator. Versatility and availability of different kinds of outputs allow the device to be integrated with any PC.


UP Monitors family contains a number of devices, form very simple models suitable for solving particular problems to complex multifunctional devices that can be employed anywhere. Using our devices one can receive position information from any type of OLTC and transmit it via digital or analog outputs.

• Alarm of boundary, first and last taps of drive position (UP23, UP25, UP31 and UP41);
• Additional discrete outputs for signals about following events: first or last drive’s tap are reached, tap switching, reaching of boundary tap position (UP23, UP25, UP31 and UP41);
• Digital output RS-485 (RS-232), used by the MODBUS RTU/ASSII Protocol, allows you to transmit information about the position of the OLTC drive to SCADA and configure the device when connected to a computer;
• Additional analogue output “Current loop” (0-5mA, 0-20mA or 4-20mA) for transmission of information on drive to SCADA position (UP23, UP25, UP31 and UP41);
• Possibility to compensate electrical resistance of connecting wires and work in configuration mode when the transformer is turned-on and located in the fixed position on one tap (UP23 and UP25).

UP benefits:

• Wide Range of Products family — one can choose a device that exactly fits to his system or use the same universal modes for different situations;
• Wide range of input types — Synchro transmitter, Current loop output, Resistive sensor, BCD encoder, RS-485;
• Wide range of data outputs — RS-232, RS-485, Analog current loop, Relay outputs, Block output signal;
• Highly configurable;
• Alarm of boundary, first and last taps of drive position;
• Additional discrete outputs for alarms about following events: first or last drive’s tap are reached, tap switching, reaching of boundary tap position;
• Digital output RS-485 (RS-232) used by MODBUS RTU/ASСII protocol that allows transferring the information on position of OLTC’s drive to SCADA system and configuring the device from PC;
• Additional analogue output “Current loop” (for transmission of information on drive to SCADA).
