  • What is a load bank?

    A load bank is a device designed to provide an electrical load for testing and maintaining the performance of a power source, such as a generator or a battery system. The purpose of a load bank is to apply a controlled and measurable electrical load to the power source, allowing operators to assess its capacity, performance, and reliability under different conditions.
    There are different types of load banks, some common types include: Resistive Load Banks, Reactive Load Banks, Combination Load Banks.
    Load banks are commonly used in industries such as power generation, telecommunications, data centers, and military applications. They play a crucial role in ensuring the reliability and performance of backup power systems, particularly in situations where a reliable power supply is critical.

    ZENITHSUN is certified to the latest quality ISO 9001, Environmental ISO 14001 and National Military Standard Quality Management System Certification GJB9001C-2017 standards. We also utilize a third party calibration services when customer requests.

  • Why test a diesel generator with a resistive reactive load bank?

    Most generating sets are designed and specified at a power factor of 0.8, and the engine is therefore not capable of delivering full kVA at unit power factor.
    Testing a diesel generator with a resistive reactive load bank involves simulating both resistive ( real) and reactive ( imaginary) loads, and it serves specific purposes beyond what resistive-only testing can achieve, includes: Power Factor Correction, Voltage Regulation under Reactive Loads, Load Balancing, Generator Cooling System Testing, Applicability to Inductive Loads, Comprehensive System Testing, Mitigation of Voltage Flicker.
    In summary, using a resistive reactive load bank for diesel generator testing allows for a more realistic assessment of the generator's performance in situations where both resistive and reactive loads are present. This comprehensive testing helps ensure the generator's reliability and efficiency in a variety of operating conditions.
