Automatic Voltage Regulating Relay, Ee-302/Ee-303
Automatic Voltage Regulating Relay, Ee-302/Ee-303
Emco Electronics offers an Automatic Voltage Regulating Relay, Model EE-302/EE-303. Features: microcontroller-based architecture with analog/digital converter; keyboard entry for parameter settings; linear or inverse time response; two independent timers for first and subsequent pulses; single pulse or continuous pulse operation; readout of prim and sec voltages in kV, volts and % deviation; independent lower and raise settings in % of nominal value; indication for pre-signals, parameter units and relay operations; auto/manual mode of operation; and high speed return action for over voltage condition. The company, established in 1973, is a pioneer manufacturer of a range of Automatic Voltage Regulating Relays, which are successfully working in field all over the country and abroad. Emco’s solid-state automatic voltage regulating relays are designed far maximum operational simplicity for regulating the secondary voltage of power transformer with OLTC. The lower and raise settings allow the deadband to be set as per requirement. The time delay control allows the regulator to respond only to voltage fluctuations lasting for periods greater than the set time delay. A pair of NO contacts is provided for operation of tap-changer. Different models of automatic voltage regulating relays are as follows: regular model EE 301-M; compact model EE 301-E; microcontroller-based model EE 302; integrated model EE 301-T with built-in TPI; and a microcontroller-based model with TPI model EE 303.
