The Beckwith Electric M-2051/M-2502 Connection Harness, used in conjunction
with the M-2001 Series Digital Tapchanger Control, uses modern electronic
digital design and digital processing circuitry to achieve an overall
stability and resolution unattainable with electromechanical and analog
design tapchanger controls. CMOS semiconductors are used throughout the
design.
Standard Features The M-2051/M-2502 Connection Harness, with the M-2001
Series Digital Tapchanger Control, provides a solid-state voltage control
relay intended for applications involving the control of tapchanging transformers
and regulators. The combination of the Tapchanger Control and Connection
Harness includes the following features:
1. Voltage waveform sampling and digital processing circuitry ensure
accurate rms voltage sensing in the presence of distortion on the input
voltage and current.
2. Accuracy exceeds the ANSI/IEEE C57.15-1986 Class 1 specification over
the temperature range of -40 to + 80 degrees Celsius.
3. Input and output circuits are protected against system transients.
Units pass all requirements of ANSI/IEEE C37.90.1-1989, which defines
surge withstand capability. All input and output terminals will withstand
1500 V ac rms to chassis or instrument ground for one minute with a leakage
current not to exceed 25 mA, for all terminals to ground. Input and output
circuits are electrically isolated from each other, from other circuits
and from ground.
4. A voltage sensing fuse and a spare fuse are provided.
