On-load tap changer (OLTC) position monitors indicate position of OLTC drives from various manufacturers and transfer information regarding drive position to SCADA system in digital and analogue view. ANTRAKS OLTC position monitors, which named UP, can work together with a large range of the On-Load Tap Changers.
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.
