When voltage is removed from terminals 85/86 and the coil is de-energised, the magnetic field that has been created around the coil collapses rapidly. This collapse causes a voltage across the coil in the opposite direction to the voltage that created it (+12V), and since the collapse is so rapid the voltages generated can be in the order of several hundred volts (although very low current).
Provides excellent heat transfer and low air resistance for maximum efficiency. Precise circuiting for uniform refrigerant distribution. Lanced fins provide maximum exposure of fin surface to air stream. Rifled tubing provides superior heat transfer. Coil thoroughly
low-voltage dry-type distribution transformers when loaded at 35 percent of their full load capacity, and for oil-based and medium-voltage dry-type transformers at 50 percent loading. Although the labeling on some products may notate “Certified” testing has been

Air conditioners are made of different types of metal. Frequently, plastic and other non-traditional materials are used to reduce weight and cost. Copper or aluminium tubing, critical ingredients in many air conditioner components, provide superior thermal properties and a
15/3/2013 · Electrical isolators separate a part of the system from rest for safe maintenance works. So the definition of isolator can be rewritten as an isolator is a manually operated mechanical switch which separates a part of the electrical power. Isolators are used to open a circuit under no load. Its main purpose is to isolate one portion of the
This explains working principle, operation and types of circuit breakers - Low Voltage Circuit Breakers, Medium Voltage Circuit Breakers, High Voltage Circuit Breakers. During the operation of power system, it is often desirable and necessary to switch on or off the various circuits (e.g., transmission lines, distributors, generating plants etc.) under both normal and abnormal conditions.
Low voltage is defined as 50 volts (V) or less. Common low voltages are 12V, 24V, and 48V. Low voltage is normally used for doorbells, garage door opener controls, heating and cooling thermostats, alarm system sensors and controls, outdoor ground lighting, household and automobile batteries.

29/5/2019 · If either of those fans isn’t working properly– due to a faulty motor, lack of lubrication, worn belts or too much dirt and debris– you end up with poor airflow and air conditioner problems. If you neglect the problem, it can lead to compressor failure, which is often a death sentence for your air conditioner. 5. Leaking ducts.
