MEMPHASE single-pole phase comparator

The MEMPHASE single-pole phase comparator checks phase correspondence between two medium-voltage three-phase circuits. It also indicates voltage presence on the tested conductors.

The MEMPHASE housing is made of white polycarbonate with excellent mechanical and dielectric properties. An adaptor at its lower end allows connection to insulating sticks with a “ universal ” head or a “ 12 mm hexagonal ”.

Advantages :

• A compact, lightweight unit suitable for outdoor (overhead lines) and indoor (substations) operations, permanently in standby

• Improved optical and audible indications, readily noticeable in most working conditions, for:

– phase synchronisation

– voltage presence

– phase memory status

The indication and control panel includes:

– the test button for the integrated checking device, which checks the electronic circuit, optical and audible signals and battery status;

– audible indication speaker;

– LEDs in different colours ( RED (2+4); BLUE (1); ORANGE (2)) for optical indication.

Technical specifications:

• Voltage presence is indicated by 2 flashing RED LEDs , together with a short audible signal

• Phase memorisation is indicated by a flashing LED BLUE and remains active for 15 seconds

• Phase correspondence is indicated by a continuously lit LED BLUE and 4 other LEDs RED LEDs , together with a continuous audible signal

• A low battery is indicated by an LED ORANGE

On request, MEMPHASE can be supplied with an electrode extension (260, 400, 600 or 900 mm), also enabling testing in indoor switchgear through access openings with a minimum diameter of 40 mm.
