Auto Reclose and Sync Check
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.

Line Injector
J2120A
While the injection transformer is a very wideband adapter, it is not useful for measuring ripple rejection (PSRR) of a power supply or even an opamp. This is because the attributes that make the injection transformer perform so well also result in a transformer that is intolerant of DC current. Even very small DC currents (5mA or less) can greatly reduce the signal capacity or even totally saturate the transformer. For this reason, the Picotest line injector (J2120A) is another essential test adapter.

Power Line Meter
The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

Universal Power Line Carrier
UPLC-ll
As with our previous UPLC power-line carrier design, UPLC-II requires no hardware modifications for most required configurations. UPLC-II is frequency programmable across the entire power-line carrier spectrum (30 to 500 kHz) without changing any hardware components. UPLC-II can be software configured either as an ON/OFF or frequency-shift keyed (FSK) power-line carrier unit without changing any hardware components. This flexibility makes each UPLC-II universally suited for any directional comparison blocking, permissive, phase comparison or transfer trip protective relay application.
