DESCRIPTION

'AE' SYNCHROSCOPE is categorized into two types A) Electro-mechanical and B) Electronic.


ELECTRO-MECHANICAL TYPE

It incorporates a POINTER and LED to indicate synchronising condition. If the generator- (II) frequency is higher or lower than that of mains- (I) the pointer rotates in clockwise or anti-clockwise direction respectively. The speed and direction of rotation depends upon difference in frequencies, which guides the operator to speed-up or slow-down the generator. Synchronising condition is determined by dark lamp method, wherein the pointer coincides with synchronising mark and the LED does not glow. The LED glows in accordance with difference in phase, frequency and amplitude of voltages. When the pointer is towards the bright LED, it indicates the antiphase condition.


FEATURES
Rugged construction.
Easy serviceability.
Wide operating voltage range.

CAUTION : The meter is not to be left in circuit after synchronising.

ELETRONIC TYPE

It incorporates circle of LEDs which glows sequentially in either clockwise or anti-clockwise direction at variable speed in accordance with difference in frequencies of mains & generator. Synchronising condition is indicated by the glowing LED of "SYNCHRO ON" position. Antiphase condition is indicated by glowing LED of "SYNCHRO OFF" position at the bottom. This LED glows under following conditions

1) Absence of mains-(l) and presence of generator voltage-(ll)
2) If generator - (Il) voltage crosses 20% When frequencies of both supplies are equal, phase angle between two voltages is indicated by glowing of LED at an approximate angle with respect to "SYNCHRO ON" position.

FEATURES
Continuous operation.
No moving parts.
Low power consumption.
Visible in dark.
