Product descriptions from the supplier
※ HGLZ-160A~1600A. The load isolation switch is suitable for the changeover of two sets of low voltage electric circuit or the changeover of 2 sets of load devices or safety isolation.
※ Mode of operation:Direct operation: handle is installed on the switch. Operation outside the board: handle is installed outside the door of power distributing board.
※ Products with observation windows can be provided according to the demand to observe directly the on and off state of contact.
※ The products have three poles, four poles ( three poles+on and off neural pole ).
※ Extended shaft is used for the operation outside the board.
※ Two sets of auxiliary contacts can be assembled acording to the demand.
※ Mechanical performance and electrical performance correspond to the mechanical property of HGLZ-160A~1600A.
※ A bridge can provided to connect the inlet or outlet terminal of the switch.
※ The electric cable insulating cover can be assembled. Note: the bridge connection is chosen, an explanation is needed to indicate the inlet or outlet is connected with it

Why Can't VT Be Shorted & CT Be Opened? ExplainedWe all know that a voltage transformer (VT) must never operate short-circuited, while a current transformer (CT) must never operate open-circuited. Short-circuiting a VT or opening the circuit of a CT will damage the transformer or create hazardous conditions.From a theoretical standpoint, both VTs and CTs are transformers; the difference lies in the parameters they are designed to measure. So why, despite being fundamentally the same type of device, is one prohibited from short-circuit operatioEcho10/22/2025 -
Why Are Voltage Transformers Burning Out? Find the Real CausesIn power circuits, voltage transformers (VTs) are often damaged or burned out. If the root cause is not identified and only the transformer is replaced, the new unit may quickly fail again, disrupting power supply to users. Therefore, the following checks should be performed to determine the cause of VT failure: If the voltage transformer has ruptured and oil residue is found on the silicon steel laminations, the damage was likely caused by ferroresonance. This occurs when unbalanced voltages orFelix Spark10/22/2025 -
Things to Know When Operating Voltage Transformers: De-energizing and Energizing ProceduresQ:What are the Operating Sequence Rules for the Secondary Miniature Circuit Breaker and High-Voltage Power Supply During Voltage Transformer De-energizing and Energizing?A:For busbar voltage transformers, the principle for operating the secondary miniature circuit breaker during de-energizing and energizing is as follows: De-energizing:First, open the secondary miniature circuit breaker, then disconnect the high-voltage power supply of the voltage transformer (VT).

How to Safely Operate & Maintain Current Transformers?I. Permissible Operating Conditions for Current Transformers Rated Output Capacity: Current transformers (CTs) must operate within the rated output capacity specified on their nameplate. Operation beyond this rating reduces accuracy, increases measurement errors, and causes inaccurate meter readings, similar to voltage transformers. Primary Side Current: The primary current may continuously operate up to 1.1 times the rated current. Prolonged overload operation increases measurement errors and mFelix Spark10/22/2025 -
How to Operate & Maintain Voltage Transformers Safely?I. Normal Operation of Voltage Transformers A voltage transformer (VT) may operate long-term at its rated capacity, but under no circumstances should it exceed its maximum capacity. The secondary winding of a VT supplies high-impedance instruments, resulting in a very small secondary current, nearly equal to the magnetizing current. The voltage drops across the leakage impedances of both primary and secondary windings are therefore very small, meaning the VT operates close to no-load under normaEdwiin10/22/2025 -
How to Improve Rectifier Transformer Efficiency? Key TipsOptimization Measures for Rectifier System EfficiencyRectifier systems involve numerous and diverse equipment, so many factors affect their efficiency. Therefore, a comprehensive approach is essential during design. Increase Transmission Voltage for Rectifier LoadsRectifier installations are high-power AC/DC conversion systems requiring substantial power. Transmission losses directly impact rectifier efficiency. Increasing the transmission voltage appropriately reduces line losses and improves rJames10/22/2025
