What could be achieved by JUNXY AC load banks ? JUNXY AC load banks could help highlight the potential hidden faults of the power supply systems before they could cause a power disruption. bThe FIRST goal achieved when testing with JUNXY AC load bank is to ensure if your power supply system is reliable or not by validating the power systems’ outputs to its technical specifications, which is the MOST IMPORTANT question that JUNXY series AC load bank could answer you. A wide range of conditions that could threaten a power system could be detected by JUNXY load banks, say defective equipment, design errors, flawed construction, emissions, natural aging, improper settings on system control components and the negative effects of underutilization.

Resistive & reactive load banks are able mimic motor loads and electromagnetic devices within a power system as well as purely resistive loads by offering the ability to set a specific power factor (pf). Many backup generators and turbines are rated at 0.7, 0.8 or 0.85 power factor and need to be commissioned at nameplate capacity using a combination of resistive and reactive load to fully qualify their operating capability. Using a resistive & reactive load bank enables comprehensive testing from a single unit. JUNXY has an extensive range of resistive & reactive load banks to simulate these types of loads on a power source and the transformers, relays, and switches which will distribute the power throughout your facility.

Inductive & capacitive load banks are reactive only and must be used in combination with a resistive load bank to provide the desired load profile to test a power system. Reactive loads banks can provide either a leading power factor (Capacitive) or lagging power factor (Inductive).

Islanding effect is not allowed in the solar photovoltaic power system regarding the power quality and electrical safety, since it will cause potential threat and damage to the electrical equipments. JUNXY RLC load banks are mostly used for inverter anti-islanding preventative test experiments which meets the PV & grid inverter testing requirements for islanding prevention detection, work efficiency test, overload protection test, over current protection test, power factor test, grid current harmonic test, resonance point test, and so on. PV Transformer and battery system maintenance should also be included for Grid-connected photovoltaic power plant operation and maintenance by JUNXY products solutions. JUNXY series DC load bank with load voltage up to DC1200V and desired load capacity to meet your different need for PV applications.
