1 Introduction

1.1 Notes on operating instructions

This operating manual was created to ensure perfect mounting, start-up, operation and maintenance, and must be read before
carrying out the following procedures. Keep this documentation handy and accessible for consultation by all users, whenever
needed. Pass on this documentation to any future users of the TSRL.

This manual contains descriptions of all necessary settings. Should any problems occur during commissioning or operation,

please do not make any unauthorised modications. By doing so, you could void your warranty. In such cases, please contact

us immediately:

1.2 Explanation of icons and symbols

Danger

Indicates a hazard that could lead to personal injury.

Danger

Indicates a hazard through electric current that could lead to serious or fatal injuries, if disregarded.

Notice

Indicates important information that could lead to e.g. material damage, if disregarded.

1.3 Intended use and foreseeable misuse

The TSRL may only be used to switch transformers with or without load. The TSRL is commonly used for isolating-, control-,

lament- and traction transformers. The TSRL is solely intended for installation in a closed device. Outside mounting is not

allowed. Please ensure correct connection assignment (see chapter 3.2 Connections and operating elements). Please note the
technical datas on the type lable.

1.4 Functions

The TSRL is an electronic device for switching of transformers. It allows inrush-free switching of one or multiple single-phase
transformers with or without load. A smooth switching procedure completely prevents and not only reduces the inrush cur­rent. For this a unipolar phase stage is created with a thyristor. For complete switching on of the transformer, the thyristor is
bypassed by an external bypass relay. The TSRL has a control input which manages on and off switching.
The half-wave-failure recognition allows the TSRL to react to mains interruptions in compliance with DIN EN 61000-4-11. This
prevents power surges during the operation and is available as an option.

1.4.1 Smooth switching procedure

The TSRL premagnetises the transformer before complete switching using unipolar voltage impulses. The strength of the
premagnetisation is the same for all transformers, and its value should amount to on by turning point of the hysteresis curve.
The width of the required voltage impulses must be matched to the different transformer types, such as packet core transfor­mers or toroidal core transformers. The potentiometer (TP1) in the TSRL is used for this purpose setting.
