COMPLEE KLY-S72-96-DR-A-B Digital Synchroscope User Manual

Introduction

1. This instrument applies as the synchronizing indicator in between power network and generator. When the voltage, frequency in between generator and power network is nearly consistency within defined time, the LED light roulette will slow down until the light stop at SYNC led (i.e. Synchronizing), and then generator can connect to the power network. Synchroscope can indicate the difference on frequency and phase angle in between generator and power network.
2. The meter is designed competitively by single chip with advanced arithmetic and accurate control.

Application Instruction

Display of front panel

LED indicates the instant phase error Δф,the resolution ratio of red LED is 15º. The resolution ratio of green LED is 3º within the range of synchronized point ±15º. During normal operation period, only one LED lights among the circular bar graph will light, the position of LED is stimulated the actual phase angle difference. Details see below diagram:

Installation Metho

Condition of synchronization for Type D synchroscope

Voltage difference of UBB and UGEN < 10%UN; Frequency difference of Fbus and Fgen < 0.5Hz; Phase angle 345°~15°

All above conditions are satisfied.

Condition of synchronization and predefined table for Type

DR-A synchroscope

1. User mustprecisely set up 3 parameters; voltage difference( △ U), frequency difference( △ F)and deferred time(Time), Each parameter
   is defined by 16 pos rotary DIP switch (from 0 to F), each pos has its corresponding value, see below table for details:

1. When turned on, users can find the code switch failure early through the panel indicating of code switch position. Voltage difference( △ U), frequency difference( △ F)and deferred time(Time) code switch position indicates in turn, each indicates about 3 seconds. The top LED light represents the switch position is 0, the LED lights in clockwise turn represents the switch position plus 1, until The top left three green LEDs light in turn respectively represents the current switch position is voltage difference(△ U), frequency difference( △ F)and deferred time(Time).
2. Condition on synchronized signal release:

Voltage difference of UBB and UGEN < △ U×UN; Frequency difference of Fgen and Fbus < △ F;
The moment before phase angle difference is 0º,and ahead of time = Time.
All above conditions are satisfied, the synchronized signal will be
