OLTC Monitors
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.
OLTC Controllers
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.
Tap sensors
DP Transformer tap sensors can be installed in the transformer changer drive.
These sensors are available in two types of enclosures:
• With dimensions similar to those of the BD404 / BD1404 synchro transmitter;
• 45 x 88 x 62 mm - which is the optimum solution for replacement of resistive sensors based on circular selectors (for example, MZ-2, MZ-2).
The sensors represent both purely resistive sensors and multifunctional sensors with analog (0-5mA, 0-2mA, 4-20mA, 0-5V, 0-24V) and digital outputs (RS-232, RS-485).
