12-Step RTR Regulator:
A regulator is a device that, by measuring the power factor of the load, introduces the required amount of capacitor into the circuit. In fact, this device determines how much capacitance should be connected to the circuit to achieve the desired power factor.
Principles of Regulator Operation: Step 1) Measuring active and reactive power
Step 2) Calculating power factor using the formula COSQ=P/PS
Step 3) Calculating the reactive power needed to reach the desired power factor
Step 4) Injecting Q kilovars of reactive power into the circuit
Capacitor regulators are divided into two categories: smart and simple. The number of steps in the regulator structure indicates the number of capacitors needed for power factor correction, which ranges from 4 to 12 steps available in the market.
Important notes for setting the network capacitor bank regulator:
1: The voltage considered by the manufacturer for the regulator should be the same as the network voltage.
2: The current transformer for feeding the regulator must be placed at the main power input to measure both capacitor current and load current.
3: The C/K value should not exceed the set value; otherwise, the error rate increases.
4: The C/K value should not be less than the set value; otherwise, although the error decreases, oscillations (continuous on/off) of one step may occur.
Q: Capacity of the smallest step of the capacitor bank in reactive volt-amperes (VAR)
V: Network voltage
K1: Current transformer ratio
K2: Voltage transformer ratio
