Metering Cubicles or Panels are indoor versions of the combined Current Transformer and Voltage Transformer (CT-VT) units. These metering cubicles or metering panels as they are popularly called are dry type units and are ideally used for indoor installations although they may be used outdoors subject to certain conditions.
Metering Cubicles consist of a combined structure which is manufactured using high grade steel which could either be hot-rolled mild steel or cold rolled mild steel depending on client requirements. The surface of the cubicle can either be painted or powder coated depending on client specifications. Surface painting can be of various types and are dependent again on client instructions and requirements.
The unit is divided into separate compartments to house the transformers and energy meter inside. It is fitted with dry type epoxy resin cast current transformers and voltage transformers and as such are dry type units. High Voltage Metering Cubicles can be used for both 3 phase 3 wire metering system or for 3 phase 4 wire metering system. In most circumstances they are used for electrical systems of medium voltages upto 33 KV.
In certain high electric systems, it is not possible to install a combined CT-PT metering unit outdoors. It could be due to multiple factors like electricity theft, excess rainfall, moisture or humidity, lack of space amongst various others. In such a situation, a High voltage metering cubicle is preferred.
High Voltage Metering Cubicles are dry type units and are the preferred transformer units for indoor installations. They may be used for outdoor applications also, if required. The outer shell or metering panel box is constructed using hot-rolled or cold rolled steel. The fabricated structure is then cleaned and painted or powder coated as per client requirements.
The structure of the High voltage metering panel are partitioned into different sections. These sections are fitted with epoxy dry type current transformers, voltage transformers and an energy meter separately so that each item is segregated from each other inside the cubicle. High Voltage Metering Cubicles are ideal for indoor use where metering is done in 3 phase 4 wire system employing 3 current transformers and 3 voltage transformers. In most circumstances they are used for electrical systems of 11 KV system voltage.
Macroplast manufactures High Voltage Metering Cubicles up to 33KV. These can be constructed according to client specifications with front door, side door or any other design specification as required by customers.
