Relay Controlled Stabilizer
Relay voltage stabilizers, also known as electronic voltage stabilizers, are devices that automatically switch transformer taps through relays to regulate the output voltage. The automatic tap-changing mechanism selects the appropriate tap based on fluctuations in the input voltage, ensuring the output voltage remains within the desired range. With a simple design and cost-effective construction, relay voltage stabilizers are one of the most common solutions for voltage regulation.

Principle of Operation for Relay Controlled Stabilizer
Detection of Voltage
The voltage at the input is detected through a voltage sensor or a control circuit and compared with the target value of the output voltage.
Relay Switching
If the input voltage shifts away from the set value, then the control system will act to trigger a relay to switch the transformer tap in order to change the output voltage.
Output Voltage Regulation
Tap switching changes the transformer output voltage to become close to the target value.
Gradual Regulation
The regulation of the relay voltage stabilizer is graded, meaning thereby that the output voltage does not change continuously but in fixed steps. This may cause inaccuracies in the output voltage of about ±10% in some cases.
Features of relay voltage stabilizer
Simplicity
The design of the relay voltage stabilizer is simple and of low cost.
Step regulation
Through the relay, the tap is switched step by step. So, in general, the accuracy of regulation is low.
Mechanical action
Relays are mechanical switches. Frequent switching will cause mechanical wear and reduce its service life.
Slow adjustment speed
Due to the mechanical characteristics, the speed of relay action is limited and hence cannot catch up with rapid voltage fluctuation.
