Introduction to BY82J S/480-40/P7 Anti-harmonic Capacitor

This top-of-the-line set of BY82J S/480-40/P7 Series Anti-Harmonic Intelligent Capacitors has been produced by Baoyu Holdings Limited. It is the very best considering its function as a Power Filtering Capacitor for 0.4kV low-voltage power systems (480V rated AC Capacitor Voltage). In the aspect of grid stability and energy efficiency, the capacitors incorporate harmonic suppression and reactive power compensation. Engineered with 7% reactance rate technology, they reduce 5th and higher harmonics hence reducing harmonic distortion and minimizing the risk of resonances in Power Systems in Series Capacitor configurations.

This AC In Capacitor with Anti-Harmonic Intelligent Capacitor technology uses zero-crossing switching enabling inrush currents to be completely eliminated, further providing an exceptionally smooth AC Current Through the Capacitor while increasing equipment longevity. It employs the design of a self-healing capacitor, which automatically heals minor dielectric faults and therefore improves performance against rigorous conditions in industrial and commercial facilities that suffer from excessive harmonic interference.

Action Principle of Each Component: Intelligent Components

Every electronic component in intelligent devices has been styled industrial-grade and applied to operate within very wide temperature ranges, wherein all such components are per se performance in temperature extreme and harsh electromagnetic environments. Extended periods can be counted for the reliability of their functioning without referring to intermittent work.

Zero Crossing Switching Synchronous Switch Technology Based on Mechanical Contacts

The analysis of mechanical contactors, contactless thyristors, and composite switches has been carried out by the company. The development or rather practical operation experience over the years has helped them in developing a technology that is right new generation of microelectronic software and hardware-based effective handling of contacts of mechanical electromagnetic relays independently. Synchronous switching technology for zero crossing and low-voltage power capacitors based on mechanical contacts ensures that their closure occurs when the AC voltage across them is zero, and opening occurs when the AC current is zero. The above-mentioned technique reduces system voltage due to inrush current at the time of capacitor input, equipment losses, and further increased lifespan of capacitors.

Dry Series Reactor

The product dry series reactor uses imports from high magnetic flux materials. Therefore, it is lightweight, compact, and energy-efficient with low temperature rise and minimal noise. It is also equipped with a thermal relay to monitor temperature and signal above the preset temperature threshold.

Micro Current Sampling Transformer

The current sampling for the capacitor employs a micro transformer with a permalloy core that provides highly usable linearity, high-frequency characteristics, and minimal deviation in current measurements and current-type protection to ensure their fidelity and stable output.

Fast Circuit Breaker

This rapid circuit breaker is a molded case circuit breaker that opens to 10 times rated current in 100 ms. It is meant to take care of any speedy current switch-off and is the only protection mechanism incorporated into upstream switch tripping. It also acts as the power connection terminal and the main power switch.

Basic Functions of  Anti Harmonic Capacitor

Harmonic Filtering Function

• Effectively suppresses harmonics and surge currents, forming a low-impedance path for harmonics. This would minimize the overload on capacitors, prevent the aging of the insulation medium, reduce its self-healing capacity, and shorten its life. Adopted an electromagnetic zero-crossing switching device that can accurately switch on zero voltage and switch off at the zero current, causing the least switch-on surge.

Signal function

• Distribution Voltage, Current, Reactive Power Measurement, and Power Factor Measurement .
• Automatic measurement and calibration of CT phase and turns ratios; internal temperature and current measurements per capacitor.Capacitance switching state, over/under compensation status, single-phase under-over voltage signals; signals for protective action type and self-diagnosis fault type.

Communication Function

• The capacitor and controller are connected via RS-485 communication to upload significantly greater amounts of sampled data and information for communication with external monitoring terminals, forming a system for operation.

Network Feature

• Provision as regards network communication and wireless network communication. 

Intelligent networking

• Automatic detection and tracking of reactive power changes in the system and thus the automatic switching of capacitor banks; capacitors of similar capacity would switch in and out in a cyclic order, while capacitors with different capacities would switch based on appropriate compensation principles; they would switch on depending on first-in-first-out and switch off in first-out-first-in order; capacitors with lower operating temperatures would be prioritized for switching on, while those with higher temperatures would be switched off first; upon the state of stability of the compensation condition, capacitors will be switched over at 15 minutes interval all the time so as not to allow a single capacitor too long operation. 

Faults Self-Diagnosis Function 

• The smart control component of the capacitor is capable of self-testing numerous operating parameters of the device itself and, once the self-test finds a fault, it has the systemic rapid response mechanism turning it off.
